The History of Gas-Liquid Chromatography of Steroids,he early reports of gas chromatography [1–3], that this tool would find its primary application in the separation of relatively volatile substances, by 1959 a number of compounds of boiling points nearly equal to steroid molecules had been gas chromatographed successfully. Notable among them are the

Column Practice,on of good analytical columns depends almost entirely upon the skill of the operator and thus it is of the utmost importance that the newcomer to gas chromatography acquire proficiency in making columns.

Decomposition of Steroids During GLC,gh it is entirely feasible to measure steroids as their decomposition products rather than in their original state, it is generally more desirable to do the latter. One of the prime reasons for trying to avoid decomposition during chromatography is the rather hazardous quantitative aspect of such pr

Determination of Urinary Pregnanetriol, formation of pregnanetriol. In turn, 17.-hydroxy progesterone is derived by hydroxylation at the 17.-position of the primary hormone progesterone. As has been discussed earlier, the latter compound has been shown to be produced by the corpus luteum of the ovary, in rather large quantities by the hu
