Gas Phase Analytical Methods for the Study of Steroid Hormones and their Metabolites, detection systems were developed. The “gas density balance” of . and . (1956) had moderately high sensitivity. The response was on a molar basis, and this detector was used extensively at Mill Hill (National Institute for Medical Research, London). Thermal conductivity detection systems (., 1946; .
