Below is a chromatogram observed from chemical separation of chlorinated pesticides using gas chromatography. Water samples were pre-treated using solvent extraction technique prior to injection into GC. Complete the statements below so that the sentences will be accurate and logical. Gas chromatography coupled with __________ __________ detector is suitable for chlorinated pesticide analysis. ii. Peaks that emerge first will represent compounds that are the most __________.Those compounds will also likely have low boiling points and show the least interactions with the stationary phase. iii. Major peaks start to emerge after 24 minutes. Heating the GC oven containing the column will likely __________ the time of chromatographic separation. iv. The peak height or area of an analyte is used to determine its __________ in quantitative analysis.
