Method for methane/CO2 analysis using HP-PLOT U

You can pick any column temp from 60 to 120 and run it isothermal with a column flow of 2-10 depending on the column ID.  2 ml for  250 column. 4 for a 320 column and 10 for a 530 column.

Thank you for your answer. What temperatures of the injection port and TCD would you recommend? I have seen 150C for injection, 250C for TCD and split ratio of 10-30:1 for other analysis methods but am not sure for my case.

Hi,

Here's few links that may help you out. In first presentation there's reference to Application Note 228-387 where they have used PLOT Q.

Hi khemmathini,

Please provide your system details also so according solution will provide.

If in your sample CO2 is greater then 20 ppm then without methanizer you can got the response or if want lower detection then you want methanizer.

Oven- 40 C ----- 6 min then 20 C upto 200C final hold 1 min.
