Free amino acids from the leaves of ten North American conifer species have been analysed by packed-column gas-liquid chromatography as their N(O,S)-heptafluorobutyryl isobutyl esters. The species examined were Balsam fir [A&es balsumea (L.) Mill], douglas fir [Pseudotsuga menzeisii(Mirb.) France],
## Abstract A carefully Standardized technique is described for the preparation of glass capillary columns which can be used successfully for routine quantitative amino acid analysis. Comparison is made between two different modes of sample injection. Preliminary quantitative results from βsplitβ i
