Sensitivity experiment of gas chromatograph

The standard gas we used was methane. How many milliliters of standard gas is generally appropriate to use? Our gas flow rate is 2.5 ml/s, which is 150 ml/min when converted to minutes. Is that too high? Last question. . . Generally, what level of sensitivity can your TCD detectors achieve?

The chromatography conditions for chromatographs from different manufacturers, especially the flow rate of the carrier gas, are not necessarily the same. Moreover, the carrier gas flow rate is related to factors such as the type of chromatography column, the type of detector, and the analysis conditions. The kind of issue you’re referring to is something that needs to be adjusted by you directly while using the chromatograph; it’s difficult for others to provide any accurate advice on it. Why not ask those around you who are familiar with your equipment and work? It’s not that the relationship with colleagues is poor, is it?
