We analyzed effluent samples via our GCMS system paired with an ATOMX purge and trap. All of a sudden, we have noticed a big increase in certain compounds concentrations and can't explain why.

Typically, we make three standards: gases, solvent liquid mix, and liquid mix and combine them together. We are noticing the third mix (in red) are producing results higher and higher than what we are target. Any recommendations on troubleshooting or what is going on? THANKS!
