How to: Non Volatile Liquid Sample Preparation in a Laboratory CHN OS Analysis. For the analysis of non-volatile liquids a simple approach is to use an inert absorbent such as glass fibre pads or Chromosorb W. Here some Chromosorb W is added to a standard pressed capsule and the liquid pipetted onto it. The Chromosorb soaks up the liquid and prevents it from leaking out when the capsule is closed.
