Abstract Content
Using techniques such Purge and Trap, GC-MS and cryofocused injection, a very sensitive automated system was developed in order to reach a LOD of 100 ppq (with regards to several VOC analytes, in particular 1,2,3 trichloropropane and 1,2 dibromoethane; requested by italian law). The sample is processed via P&T, the trapped analytes will be desorbed into a PTV inlet kept at low temp by means of liquid CO2. The whole amount of every analyte is then transfered by ballistic PTV heating into GC column and detected by single quad in SIM mode.
