CHNS/O Elemental Analysis
Analysis of gases produced by efficient combustion of compounds containing C, H, N, and S elements in an oxygen stream, followed by gas chromatography of CO₂, H₂O, N₂, and SO₂.
Pyrolytic decomposition of solid and non-volatile liquid samples for oxygen content determination.
Dynamic gas chromatography (N₂, H₂, CO₂, CH₄, H₂O, VOC, etc.).

Determination of gas adsorption/desorption capacity
Determination of the adsorption/desorption capacity of gases bound in materials, expressed in mmol of gas per gram of material.

Determination of diffusion coefficients
Processing of dynamic data allows the determination of how quickly a gas diffuses through a porous material.

Measurement of adsorption/desorption kinetics
Measurement of the rate and amount of gas adsorption on the surface of a material or its release during desorption.

Characterisation of porosity
Based on the interaction of gases with the material, the size, distribution, and volume of pores can be analysed.

Study of transport properties
Dynamic gas chromatography (dGC) is useful for studying membranes and their permeability to various gases.

Analysis of reaction mechanisms
Applied in the study of catalytic reactions occurring in the gas phase on the surface of solid catalysts.

Static gas chromatography GC-FID/TCD with tower and HeadSpace autosamplers
Analysis of volatile organic compounds, water, and non-corrosive gases (H₂, CO, CO₂, N₂, Ar, Kr, Xe, alkanes, alkenes, alkynes, arenes, water, etc.).

HPLC UV-Vis MS and UPLC PDA HRMS
For all analytes soluble in solvents, particularly thermally unstable compounds, pharmaceuticals, vitamins, and industrial chemicals. Possible modes include:

• Adsorption chromatography (normal/reversed phase C8, C18), size exclusion chromatography (SEC/GPC, aqueous solutions), and separation of chiral compounds (cyclodextrin).
• Determination of characteristic retention (retardation) factors (RF).
• Relative determination of compound hydrophobicity/hydrophilicity.
• Accurate molecular ion mass determination (positive/negative).
• Fragmentation experiments – assessment of relative stability of molecular ions and structural information.

Karl Fischer Coulometric Titration
Determination of water content in gaseous, liquid, or solid samples – excluding DMSO, lithium iodide, and nitro- or nitroso-hydrocarbon derivatives.
