Dmv Multiple Choice Test Flame Ionization Detectors (shortened FID) is a common type detector used in gas chromatography. These detectors are best at detecting organic compounds. The first flame ionization detector was developed in 1957 in Australia. The purpose of a FID is to detect compounds as they exit out of the gas chromatography column.
Gas chromatography was used to separate two similar compounds, methylcyclohexane and methylcyclohexene. A 40.0 cm packed column with OV-1 stationary phase yielded the following results: 11 Retention time Base width air (unretained) 1.9 min methylcyclohexane 10.0 min 0.76 min ...
