The present disclosure describes a unique, two-part, water-soluble polymer matrix material and a method of application that immobilizes a wide variety of loose powder or crystalline hazardous materials and renders them 'safe' or at least “safer” for handling and transport. The polymer matrix material is a two-part polymer material comprising a liquid cross-linking polymer and a cross-linking agent, initiator, or biocide contained in a solution. The cross-linking agent functions to cross-link the polymer and cause it to harden in place.

The present disclosure describes an improved sample preparation technique and adapter device for the removal of trace materials from swabs and delivery of the trace materials into a mass spectrometer (MS) or an ion mobility spectrometer (IMS). The adapter device and technique aids the delivery of the analyte into the instrument inlet and concurrently serves as an ionization source. The technique includes the steps of positioning or shaping the swab so that a pointed analyte release corner or tip is directed toward the inlet of the MS or IMS, adding a solvent to the swab and charging the swab to create an ionized analyte spray pointed at or positioned within the inlet of the detection instrument.
