Carbazole via 8270
Posted: Thu Sep 08, 2011 6:17 pm
Hello,
we are currently having a problem with Carbazole when running the 8270 method. We can run an initial calibration curve and the compound responds linear over the course of our curve. Our main problem is that when running our continuing calibration we notice that the compound appears to responding in an increasing fashion and is one of the first compounds to fall out of spec.
Has anyone seen this happen with their instrumentation? Any tricks or advice?
We are running with a HP 6890 GC and 5975C Agilent MSD
Thanks,
Jeff
