MARKES UNITY 2 is a cryogen-free two-stage manual thermal desorber for tagged or untagged tubes. It is used for sampling, concentrating, extracting and analysing volatile and semi-volatile organic compounds from a range of real-world sample matrices.

Airborne molecular contaminants (AMC's)Airborne molecular contaminats can be classified as being either acids (HCl, HF, HNO3 H2SO4), bases (NH3, amines, N-methyl pyrollidinone), condensables (organics with boiling points >150°C) or dopants (P, B, As compounds) according to SEMI F21-95. 

Industry standard methods include ASTM F1982-99 (standard test methods for analysing organic contaminants on silicon wafer surfaces by thermal desorption gas chromatography) and ASTM F1227-89 (standard test method for total mass loss of materials and condensation of outgassed volatiles on microrelectronics & related substrates).
