Delay between Samples
Delay between Samples

Hi everyone, Our lab own a microGC 990 with aPORAPLOTU column.The software we use is Openlab.I usually run my samples with "sequence" mode.Is there a way to put a "delay time" between samples?

Hi everyone, Our lab recently purchased a microGC 990 (it has a TCD detector) with an OpenLab software.We want to measure CO2 concentration in ambient air (<500 ppm or <0.05%).We have thePORAPLOTU column.Can this very dilute concentration be measured by adjusting some parameters?I tried increasing injection time!that seems to help.
