Every batch of e-liquid produced by Virgin Vapor is run through our state of the art GCMS machine.  GCMS stands for gas chromatography–mass spectrometry, a sophisticated analytical method for analyzing compounds present in a given sample.  GCMS machines are commonly used in forensic science as well as at airport security check points and are known for their extreme accuracy in detecting even trace elements in a given sample.  Our GCMS machine gives us detailed data on every batch of e-liquid, creating a unique picture of each sample, much like a finger print.  Virgin Vapor uses this data to ensure that the nicotine level is correctly identified and the flavor profile is consistent from batch to batch.  We also use our GCMS to perform ongoing testing for diacetyl, pentanedione and other diacetyl analogues.  In addition, we test for DEG in our vegetable glycerin and are constantly expanding our testing protocols.
