Hi,
Currently, my company is interested to analyse IPA, Acetone and PGMEA liquid impurities and check the purity content using GCMSD. The solvent purity involved are 99.99% pure. Has anybody done the analysis or may i know where to get the application info?? Pls assist me in this matter. Thank you very much
Best wishes,
Steven

99,99% pure means, that there is 0,01% to be analysed. This equals 100ppm(roughly speking). An average GC/MS system should not have problems with that concentration range - as far as the 100 ppm are volatile enough to become gaseous in the injector. Check the regulations of your industry if there are any.
