Split/Splitless Gas Chromatography Injection

and so this is the most sensitive the method can be: a splitless injection. Finally, you might ask what’s going on with the septum purge: note that in this example is it 2 mL/min in whatever mode the analyst uses (splitless or split). The constant septum sends clean, carrier gas past the bottom on the septum and out to waste.

Gas Chromatography-Mass Spectroscopy

splitless mode. All the analyte mass in a 1 µl injection goes onto the column, it is not split. Finally, the septum purge outlet prevents septum bleed components from entering the column. The constant septum purge flow sends clean, carrier gas past the …
