SMT-TNT columns are specially designed C18 column for use in the reversed-phase separation of nitroaromatic and nitroamine derivatives. The isomeric nature of these explosive compounds is the reason for the difficulty in their separation.
The standard test method for the analysis of seven nitroaromatic and nitroamine explosives in soil by HPLC specifies the use of two reversed-phase columns [C18 and CN] in series.
A new HPLC method developed using SMT TNT1 is very simple and results in separation of six nitroaromatic explosives in fifteen minutes or less with a single column using a simple isocratic elution.
Unique features of SMT-TNT columns:
- Highly reproducible mixed bonded phase; consistent separation of analytes, Increased longevity provided through Total Coverage?
- The column also offers enhanced separation for pesticides, herbicides, pharmaceutical metabolites, polar natural products and other polar biomolecules.
