Acclaim ExplosivesChapter 8: Acclaim ExplosivesE1 and E2 ColumnsFor the separation of the 14 explosives targeted byEPA SW-846 Method 8330The novel and unique chemistries of these columns providesuperior resolution to other commercially available columns. TheAcclaim Explosives columns provide a "Total Solution" to EPAMethod 8330; two columns each of which provides baseline resolutionof all 14 explosives. The Acclaim Explosives E1 providesselectivity similar to conventional C18 columns. The Acclaim E2column provides selectivity that is complementary to that obtainedusing the Acclaim E1 and is recommended for the confirmatoryanalysis. With their complementary selectivities, the E1 and E2provide both primary and confirmatory columns.EXPLOSIVESAcclaim Explosives ColumnsThe Acclaim Explosives E1 and E2 are specialty reversedphase columns that have been optimized and application testedfor the separation of the 14 explosives targeted by EPA SW-846Method 8330, “Nitr<strong>oa</strong>romatics and Ntramines by HPLC.”Fourteen Target Explosives Listed in EPA Method 8330CH 3NO 2O 2 N NO 2NO 2 N N N NO 2NNO 2NO 2TNTHMXNO 2 N2-NT 4-NT 3-NTNO 2NRDXNNO 2NO 2 NO 2NO 2NH 2CH 3NO 2CH 3CH 3NO 2CH 3CH 3NO 2O 2 N NO 2NO 2NO 22,6-DNT 2,4-DNT1,3-DNB NBCH 3CH 3 NO 2O 2 NO 2 N NO 2NO 2 NH 2O 2 N NO 22-A-4,6-DNT4-A-2,6-DNT 1,3,5-TNBH 3 C NO 2NO 2 N NO 2NO 2Tetryl22770AUBaseline Separation of 14 Target Explosive CompoundsListed in EPA SW-846 Method 8330Peaks: 1.
