What reagent can be used to stabilize a mixture of benzene, toluene, ethylbenzene and xylene?

13 May 2024 0 7K Report

I am plotting a calibration curve of benzene, toluene, ethylbenzene, and xylene (BTEX) in water. I have been struggling to get a good straight-line calibration curve because of the volatile nature of xylene and benzene. Do I need to add a stabilizing agent to the mix?
