Please click here to know about some of the Agilent J&W GC Column Test Standards. You can compare your column's performance to the test chromatogram shipped with your J&W column from Agilent. The column test standard contains components that test the column for resolution characteristics, efficiency, and inertness. The test mixes are supplied at a concentration of 250 ng/μL in 2 mL vials. Match the phase and column diameter in the chart mentioned to find the test mix for your column.
Please contact your local Agilent Technologies representative if you need more information.
