High-Resolution Separations of Explosives and Related Compounds
Purospher® RP-18 HC HPLC column is a non-endcapped stationary phases, designed for high-resolution separations of explosives and related compounds. The column allow the determination of traces of explosives in soil and water samples, in combination with solid-phase extraction. This is of great importance for applications such as hazardous waste site characterization. With the Purospher® RP-18 HC HPLC column, 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) can be easily separated from each other. The columns are also suitable for the separation of piric acid from hexyl, and ethylene glycol dinitrate (EGDN) from diethylene glycol nitrate (DEGN).
Features and Benefits
- High-resolution separations of explosives and related compounds
- Accurate trace analysis of explosives in soil and water samples
