Purospher® RP-18 HC
Purospher® RP-18 HC is a non-endcapped stationary phase providing high resolution for the separation of explosives and related compounds.
The determination of traces of explosives in soil and water samples in combination with solid-phase extraction is of great importance for scenarios like hazardous waste site characterization. With this HPLC column, also microbial transformation products of TNT (2-amino-4,6-dinitrotoluene [2-Am-DNT] and 4-amino-2,6-dinitrotoluene [4-Am-DNT]) and manufacturing impurities of TNT (2,4-DNT, 2,6-DNT, and 1,3-DNB) could easily be separated from each other. Purospher® RP-18 HC is also suitable for the separation of picric acid from hexyl and ethylene glycol dinitrate (EGDN) from diethylene glycol nitrate (DEGN).
