Application
Nukol capillary GC column may be used for quantitative determination of free volatile fatty acids (FVFA) from dairy products. It may also be used for the determination of the free concentration of valproic acid in human plasma by equilibrium dialysis followed by solid-phase microextraction (SPME) and capillary gas chromatography.
The Nukol column is used for the analysis ofvolatile short-chain fatty acids (SCFAs). The Nukol column is specificallydesigned for volatile acids, allowing for the effective separation andquantification of these compounds in fecal samples. The GC system with theNukol column facilitates the measurement of SCFA concentrations, which are important metabolic products of gut microbial fermentation.
