Sample Preparation

 

Neat Preparation

Neat samples were analyzed directly out of the vial or off of the sample, i.e. condoms.

          - DART: The closed end of a micro-capillary tube was dipped into the sample prior to instrument introduction.
          - FTIR: 2 uL of the sample was pipetted onto the ATR crystal for analysis.

 

Extract Preparation

DART-HRMS: 80,000 ppm w/v extracts solutions of each sample was prepared in either methanol or hexane by weight for DART analysis

GC-MS: 1000 ppm w/v solutions of each sample was prepared in either methanol or hexane by weight for GC-MS analysis. All extracts were prepared with a 10 ppm v/v tetrachlorethylene internal standard (IS).

FTIR: 80,000 ppm w/v extracts solutions of each sample was prepared in either methanol or hexane by weight for FTIR analysis
