Gas chromatography (GC) of barbiturates is currently carried out mostly on the bis-N,N'-alkyl derivatives. Free barbiturates, even on apolar or medium polar phases, adsorb irreversibly, rendering GC difficult or impossible [ l ] . This behaviour is observed both for
sample patterns 8, 14, and 22, respectively, require about 1.5, 2.0, and 2.5 men per day. The assay takes a little longer than a mouse convulsion test, but is many times moreaccurate. Since we were not assaying serum insulin we were able to increase volumes, standard concentrations, and I1al-insuli
## Abstract Preβchromatographic reactions are no longer a necessary evil. Equipment such as the microrefluxer now allows reproducible 7βΞΌlβreactions to be carried out in a short time. Thus multiple derivatisations can be used together with glass capillary GC for routine identifications. The method
