Cold injection techniques and low temperatures can be used to minimize that. To prevent polar analytes from getting lost or stuck in GC, the system must be well-maintained and the analytes must be derivatized. Issues One of the major problems with gas chromatography is leakage. As the mobile ...
The sample passes through a sample line to the sample conditioning system (SCS) where it is filtered or otherwise conditioned. After conditioning, the sample flows to the analyzer assembly for separation and detection of the gas components. Figure 1: Gas Chromatography Process Model A. Process ...
Gas chromatography 气相色谱Introduction Gaschromatography- specifically gas-liquid chromatography - involves a sample beingvapourisedand injected onto the head of the chromatographic column. The sample is transported through the column by the flow of inert, gaseous mobile phase. The column itself ...
