Abstract Using the Agilent G1888 Network Headspace/6890N GC/5975 inert MSD system several primary packaging materials for pharmaceuticals were evaluated in a study. In this Application Note results for two of these materials, a labeled HDPE bottle and a soft elastomer liner from the inside of the screw cap are presented. A multiple headspace extraction technique (MHE) was used and the highest attainable amount of extractables that could ever be concentrated in the drug product was calculated. Further, the extraction efficiency of the MHE procedure was studied using benzaldehyde and phenol as target compounds. The analytical results obtained from the inert 5975 headspace-GC/MS provide excellent sensitivity when utilizing SIM/Scan data acquisition with multiple headspace extraction (MHE). The synchronous SIM/Scan feature of the 5975 MSD allows for very low level SIM detection while also searching for unkowns using scan data.
