Derivatization reagents for GC, alkylation, methylation, TMSH Other - ICP-MS Calibration Standard 19-100-5ANTMSH is used for methylation of fatty acids, because it is just necessary to add the reagent (0. 2 M in methanol) to the sample solution. Removal of excess reagent is not required, since in the injector of the gas chromatograph at 250 C pyrolysis to volatile methanol and dimethylsulfide will occur. Due to the high reactivity, complete derivatization is often obtained at ambient temperature. However, heating (e. g., 10 min at 100 C) in a closed sample
