Detailed explanation-1: -One way to optimize your GC analysis is by using retention gaps and guard columns. Although similar, they can serve different purposes. A guard column/retention gap is a short (1-5 m) piece of uncoated deactivated fused silica tubing which is placed in-line between the GC injection port and the capillary column.
Detailed explanation-2: -It is critical that the GC outputs accurate, repeatable results to ensure differences between two sample injections are only due to differences in chemical composition. It is therefore imperative to keep the flow rate of the carrier gas constant, as deviations disrupt the detection of chemical compounds.
Detailed explanation-3: -For capillary GC, split/splitless injection is used.
