In this post, I will provide suggestions to help you reproduce the results of the QA test chromatogram that was included with your column set.
D3606 Column Sets (cat.# 83606-)
Thoroughly review the instruction sheet for this column set:
Verify the temperature of your GC oven is 135 °C by using an accurate thermometer or digital thermocouple thermometer. Do not simply rely on the instrument temperature display.
Verify the carrier gas flow rate (of helium or nitrogen) is 20 mL/min by using a high-quality digital flow meter (cat.# 22656). Head pressure will be approximately 65 psi.
Carefully follow the instructions listed in ASTM D3606 for setting the correct backflush time for your particular instrument (approximately 2.4 minutes).
Make sure columns are correctly installed (oriented) to your inlet and valve (see our instruction sheet for details).
Using a high-quality electronic leak detector (cat.# 28500), thoroughly check each connection to verify it is leak free.
I hope you have found this information helpful. If you have any questions, please email us at technical service.
