“…Transistors may also function as the sensor in a TCD at temperatures <200 °C, although they are also flow sensitive (660). The development of an AC or square wave TCD was continued by Ediz, van Swaay, and McBride (237).…”

This review surveys developments in the field of gas chromatography since publication of the last review in this series (178) and covers the years 1972-73. Gas chromatography continues to be one of the most active areas in analytical chemistry. In the 1973 Directory of Membership of the ACS Division of Analytical Chemistry (356), those listing their research specialty as "gas chromatography" were second in numbers only to those listing the drugs compiled by the editorial staff (423) and articles on applications of GC in alcohol analysis (417), hallucinogenic drugs ( 818), the analysis of narcotic analgesics and amphetamines (622), barbiturates (446), and phenothiazine drugs (158).
