Analysis

The Atomic Absorption Spectroscopy (AAS) is used in the laboratory to measure the content of metals in inorganic or organic samples. The AAS can be performed with both flame and electrothermal atomization. The samples are measured in the form of solutions in water or organic phase (methanol, ethanol). In some cases, decomposition methods can be employed. The determination of mercury can be performed also in solid samples.

The following elemental analyses are performed in the laboratory (detection limit in mg/l for flame atomization):

 Ag (0.03)

 Al (0.4)

 As (0.6)

 Au (0.1)

 

 

 B (8)

 Ba (0.2)

 Be (0.02)

 Bi (0.2)

 

 

Ca (0.01)

 Cd (0.005)

 Co (0.05)

 Cr (0.06)

 Cs (0.04)

 Cu (0.04)

 Fe (0.05)

 Ga (0.7)

 Ge (1.5)

 Hg (5)

 In (0.2)

 

 K (0.01)

 La (1)

 Li (0.02)

 Mg (0.003)

 Mn (0.02)

 Mo (0.3)

 Na (0.003)

 Ni (0.05)

 Pb (0.1)

 Pd (0.1)

 Pt (1.5)

 

 Rb (0.03)

 Rh (0.15)

 Sb (0.3)

 Se (0.5)

 Si (1.0)

 

 Sn (1)

 Sr (0.05)

 Ta (11)

 Ti (1.5)

 

 

 Tl (0.3)

 V (0.75)

 W (6)

 Zn (0.05)

 

 

 

For some elements, it is possible to achieve lower detection limits by combination of AAS with electrothermal atomization (Hg) or AAS with hydride technique (As, Se, Sb). These methods have to be discussed individually.

Laboratory of NMR spectroscopy is the part of the Central Laboratories of the University of Chemistry and Technology (ICT) in Prague. The main goal of our laboratory is to measure service NMR samples delivered not only by various school laboratories but also by out-of-school institutions. Apart from basic services we are able to perform more complex non-standard experiments involving their interpretation and evaluation. At the same time our laboratory deals with scientific and teaching activities that involve close cooperation with other departments of ICT.

NMR spectroscopy can be widely used for characterization of organic compounds. In addition to determination of chemical structure of various products and reactions intermediates, NMR is applicable also for mixture component analysis, kinetic and thermodynamic measurements. NMR is also a powerful tool for quantitative and qualitative calculation of geometry of the molecules and their dynamics.

Enormous development of advanced techniques enabled NMR spectroscopy to become the significant method for calculation of the structure of biomacromolecules – proteins and nucleic acids. At present we are solving the spatial geometry of selected proteins of Mason-Pfizer monkey virus.

About thermal analysis

The methods of thermal analysis enable us to offer the following types of sample/material testing:

  • Processes taking place under the heating stress connected with mass change (drying, dehydration, oxidation, …)
  • Heat exchange (melting, crystallization, glass transition,…)
  • Influence of conditions (heating rate, temperature range, atmosphere, …) on thermally-stressed materials
  • Thermal stability (decomposition, oxidation, …)
  • Design and verification of heat treatment procedures for a wide range of materials

 

Principles

Thermogravimetric analysis (TGA)

A sample is subjected to a controlled heating/cooling program (non-isothermal or isothermal) and its weight is measured over time at a range of temperatures.

Differential thermal analysis (DTA)

The sample is heated/cooled at the chosen temperature rate at the same time as a reference, which will remain constant. The temperature difference caused by changes in the sample is recorded and the type of interaction monitored as it takes place. The dependence of the temperature difference on both temperature and time shows the heat aspect of the interaction taking place during the heating or cooling of the sample (exothermic or endothermic effects).

Differential scanning calorimetry (DSC)

DSC monitors heat effects associated with the phase transitions and chemical reactions as a function of temperature. Through appropriate calibration, the results are converted from microvolts to milliwatts. These results show the effects of the interactions and amount of exchanged energy.

Mass spectrometry (MS) combined with thermal analysis (TA)

The quadrupole mass spectrometry analyser enables the detection of chosen masses up to 300 amu. The masses are related to the gases that evolve during the thermal treatment of the sample.

Fourier transform infrared spectroscopy (FTIR) combined with thermogravimetric analysis (TGA)

The infrared spectrometer enables the analysis of the gases that evolve from the thermal analyser during sample analysis.

Laboratory of X-ray diffractometry and spectrometry is part of the Central Laboratories at the University of Chemical Technology in Prague. Its main mission is the determination of phase composition using X-ray diffraction analysis(XRD) involving the measurement and evaluation of diffraction patterns and elemental composition by X-ray fluorescence analysis (XRF) of samples supplied from university departments but also from outside the university. In addition to the basic service, specialized or complex experiments, including evaluation can be performed.

X-ray powder diffraction analysis (XRPD, mineralogical analysis, phase analysis) could be used to measure solid samples in the form of powders or flat compacts to determine amorphous or crystalline state of samples. The determination of crystalline phases is performed on the base of comparison  measured d, I values with d,I values in databases PDF-4+(Powder diffraction file, inorganic measured and calculated data) or PDF-4/Organics (organic calculated data). Database PDF-4+ includes cards (reference 04-) with x,y,z coordinates of atoms, which could be used for quantitative Rietveld`s analysis.

XRD analysis is mainly used to characterise solid samples, inorganic and organic. Laboratory deals with all chemical problems having relation to solid phase, solid state reactions and heterogeneous systems. It can provide information about progress of solid state reaction, about qualitative and quantitative phase composition of solids, crystalline polymorphism, crystallite size (1-500nm), degree of crystallinity, structural perfection, texture. Special area is molecular and crystal structure of organic or inorganic compounds from single crystals, high-temperature  measurement of powders in the range 20-1400°C.

XRD became an indispensable method for studies of corrosion processes, catalytic reactions, synthesis of ceramic materials and pharmaceutic substances(API), research of semiconductors. XRD is not a trace analysis,  0.1 hm.%. is the Limit of Detection(LOD). Recommended quantity of sample for XRD is in section Service. XRD measurement is non-destructive and sample can be used for another analysis.

MicroXRD deals with spot analysis in range 0.1-2 mm. The main advantage is possibility to analyse no-plane compacts in different shapes (e.g. pipes, wires).

X-Ray fluorescent analysis is used to determine elements in range Be-U in powders or compact samples. It is possible to measure liquids as well with restriction to range F-U and worse detection limits for F-Si. Liquids are measured in cups, bottom of the cup is foil, usually 6 micrometer mylar or 4 micrometer polypropylene. Measured liquid must not react with foil, preferably having pH in range 5-7(F-Mg are measured with WD spectrometers). Thera are almost no restriction on pH and reactivity of liquid when ED spectrometer is used, but only Al-U elements can be measured. XRF is suitable for determination of more elements simultaneously (standard F-U), limit of detection generally  improves with growing atomic (proton) number, advantage is low overlap among elements, light elements Be-Si should be measured on samples with  smooth surface.  This is really necessary for Be-O. Recommended quantity of sample for XRD is in section Service. The measurement is mostly non-destructive (warning-glass may darkened). The element composition of glass, cements, ashes, clays, alloys is the main application.

X-ray single crystals diffraction is used for determination of molecular and crystal structure of organic or inorganic moleculs(up to 100 nonH atoms in asymmetric part of cell). Single crystal with size in range 100-1000microns is necessary. Growing of single crystals from solutions can be performed in laboratory, at least 50mg of sample and knowledge about solubility in different solvents is necessary.

Laboratory of Molecular Spectroscopy is the part of the Central Laboratories of the University of Chemistry and Technology (UCT) in Prague. We are mainly focused on analysis of unknown substances, identifying their functional groups, verifying the purity of substances and determination of mixtures composition using Infrared (FT-IR) and Raman spectroscopy.

Infrared and Raman Spectrometry can be used in many fields, such as structural analysis of organic and inorganic materials, analysis of foreign substances in the environment, analysis of combustion gases, polymers, sorbents, fillers and adhesives of paper and resins, adhesives for denture, analysis of dyes, fillers and emails used in art and historical works.

Infrared Spectrometry is also used in food analysis (determination of sugars or ethanol in alcoholic drinks, analysis of wines and honey), in medicine (bladder stones), in ecology (determination of petrochemical substances in air and soil, determination of respirable silica in the air, detection of allergenic pollen) and in industrial analysis (determination of additives in oils).

The scientific activity of the laboratory is focused on the development and improvement of measurement methods and on combining of the results obtained by various measurement techniques, which lead to a more reliable solution of the analytical problem.

The elemental analyses are focused on the determination of following elements – carbon, hydrogen, nitrogen, sulfur, chlorine, bromine, iodine and phosphorus. Analytical methods are based on a sample high-temperature burning in oxygen atmosphere and with a subsequent detection of selected burning products.
Solid or liquid samples can be analysed, e.g. pure chemicals, fuels, coal, heavy oils, plant materials, wood, cellulose etc. Some soils, sands, clays, sediments and other samples being partially or predominantly inorganic can be analyzed. The samples are always destroyed by burning (analyses are destructive).

Analyses

1. Simultaneous determination of carbon, hydrogen, nitrogen and sulfur from one sample
Vario EL Cube analyzer is used for this determination. The analyzer is equipped with a TCD detector and additionally IR detector which is used for determination of the low sulfur content ( below 100 ppm).

Simultaneous C, H, N, S determination is based on high-temperature (up to 1200°C) combustion of the sample in the oxygen stream. Gaseous products of combustion (N2, CO2, H2O a SO2) are purified, separated and finally determined by TCD. Typical samples are organic chemicals but lot of inorganic matters can be  analyzed as well.

If your sample contains fluorine in any form and quantity, then the sulfur content cannot be determined. Fluorine containing samples can be analyzed only by the Vario EL III analyzer. In the case of flourinated samples, we can only do the determination of carbon, hydrogen and nitrogen content.

2. Trace and semi-trace determination of halogens and sulfur
We are able to determine even very low content of halogens (not fluorine) and sulfur. These analyses are carried out by the Mitsubishi TOX – 100 analyzer.

Trace and semi-trace determination of halogens:
The sample is burnt in the oxygen-argon atmosphere. Hydrogen chloride produced by sample burning flows into the titration cell where the microcoulometric titration by Ag+ ions takes place. Ag+ ions are automatically generated by Ag - electrode.


Trace and semi-trace determination of sulfur:
The sample is burnt in the oxygen-argon atmosphere. Sulfur dioxide produced by sample burning flows into the titration cell where the microcoulometric titration by I3- ions takes place.

Trace determination of sulfur is disturbed by nitrogen and halogens. If the determination has to be done, your samples cannot contain nitrogen and halogens.
Trace determination of halogens (not fluorine) is disturbed by high sulfur and nitrogen content. If the determination has to be done, your samples can contain sulfur and nitrogen up to 10 %wt. In the case of samples of unknown chemical composition, we have to do the simultaneous C, H, N, S determination at first.

3. Determination of chlorine-, bromine- and iodine content
Methods of classical argentometry are used for the determination of the halogens content. However methods are slightly modified to be able to analyse low quantity of halogens. The sample weight needed for the analysis is depended on the expected halogen content.

The sample is burnt in the oxygen atmosphere inside of the Erlenmeyer flask. Gaseous products of burning are absorbed into the working solution of hydrogen peroxide that is subsequently transfered into the titration flask. The halogen content is determined by potentiometric titration using silver nitrate as titrant.

Your sample has to be a solid and easy burnable matter.
If the estimated halogen content is bellow 5 wt% then the sample mass needed for one analysis is at least 100 mg. If the estimated halogen content is above 5 wt% then the sample amount needed for one analysis is 20 mg.

4. Phosphorus determination
The sample is burnt in the oxygen atmosphere and mineralized. The phosphorus content is determined by a modified complexometric titration.

The sample must not contain alkali earth metals.
If the estimated phosphorus content is low (approx. 0.1 wt%) then the sample amount must be at least 800 mg in one analysis!
