GC Sensitivity Test

Hi Sergio,

Can you let us know the model of GC you are working with as well as the method parameters?

Hi James,

We are working on a GC 7890B. The method parameters are as per the Agilent 7890 A/B Maintenance and Troubleshooting manual.

HP5 Column 19091J-413 30 m X 0.32mm X 0.25um, 6.5 mL/min, constant flow

Inlet: 250 C, splitless, purge flow 60 mL/min, purge time 0.75 mL/min, septum purge 3 mL/min

Detector: 300 C, H2 30 mL/min, air 400 mL/min, Make up 25 mL/min

Oven initial 40 C, ramp 1 rate 25 C/min, ramp 2 rate 15 C/min hold 2 minutes, run time 9.33 minutes

Oven parameters differ a little bit from the parameter in the manual

I will mark this as assumed answered due to its age, feel free to update us with what you found or post again if this is still an issue.

Regards

James
