Partial flame ionization detection

Fig. 5.3. Partial gas chromatography (GC) profile of ethyl esters of (a) a "2 isomer type" and (b) a "4 isomer type" CLA supplement, using a 100-m CP Sil 88 fused silica capillary column and flame ionization detection (FID). Product (a) is identical to product No. 14 and product (b) is identical to No.17 in Table 5.1. Note co-elution of 8-trans, 0-cis and 9-c/s,11 -trans. Fig. 5.3.

With the FID, the substances to be detected are burned (oxydized) in a hydrogen flame and are thus partially ionized (Table 2.33). The FID is a mass-flow-dependent detector. The signal is dependent on the rate at which analyte molecules enter the detector from the analytical column. The response of the FID is not affected by the makeup gas flow rate. [Pg.192]
