For determination of composition
The determination of qualitative and quantitative composition
Liquid chromatograph
Waters ACQUITY UPLC H-Class Core System ar Column Heater 30-A, TUV, ELS, Fluorescence Detectors
- UV detector: wavelength 190 up to 700 nm.
- Fluorescence detector: excitation wavelength 200 up to 890 nm, emission wavelenght 210 up to 900 nm.
- Light scattering detector: gas – nitrogen, nebuliser – heating 0 till 100 %, cooling, temperature of the evaporating tube from 5 till 100 oC.
X-ray diffractometer
For the identification of the composition of solid, crystalline substances (powders and monoliths – determine crystalline phases (eg. minerals), sensitivity of impurities of ~ 2 – 5%, it is possible to compare the crystallinity of the samples. Can be a non-destructive analytical method, the sample can be returned intact. Briefly about the method (in English).
Scanning electron microscope
It is possible to determine the homogeneity of the sample composition (result – image), it is possible to determine the chemical composition in a specific area (eg. 1×1 µm), to perform identification of point inclusions – determine the chemical elements present in the sample and their proportion. Pore dispersion and distribution can be assessed visually, measure pores, crystals, etc. object sizes. Can be a non-destructive analytical method, the sample can be returned intact. See more in microscopes.
FT-IS spectrometer
Fourier Transform Infrared spectrometer. Method of analysis of solids, determine functional groups or chemical bonds, eg., detached P-O from P=O.
