- ... The derivatization of organoarsenic compounds by different reagents like thioglycolates or dithiols and the subsequent analysis by GC–MS as a molecular specific technique was investigated and described. The possible derivatization reagents methyl- and ethylthioglycolate (TGM and TGE), 1,3-propane- and 1,5-pentanedithiol (PDT and PeDT), which transfer the polar and nonvolatile analytes dimethylarse ...
