Acclaim Explosives LC Column
Acclaim Explosives Columns: A Total Solution for EPA Method 8330
The Thermo Scientific Acclaim? Explosives E1 (5 μm) and E2 (5, 3 and 2.2 μm) silica-based
reversed-phase columns are designed to resolve all 14 explosives listed
in EPA SW-846 Method 8330: Nitroaromatics and Nitramines by HPLC. Their
unique chemistries deliver superior resolution with complementary
selectivities. The E1 is recommended for use as a direct replacement for
ODS columns for the primary analysis.The E2 may be used as either a
primary or a confirmatory column.
-
Two column chemistries, each offering baseline resolution of all 14 compounds targeted by EPA Method 8330
-
Mutually-complementary selectivity
-
Simple, isocratic elution conditions
-
Rugged columns with good lot-to-lot reproducibility
-
Unique selectivities for separating other nitroaromatic molecules
The
Acclaim Explosives stationary phases are based on ultrahigh-purity
spherical silica gel particles, with 120 ? pore size. The Acclaim
Explosives E1 is available in a 5 μm particle size and E2 columns are
available in 5, 3 and 2.2 μm particle sizes. The unique chemistry of
these columns offers exceptional selectivity and stability over the
range of pH 3.0 to 7.0, and their design ensures good column life and
easy cleanup.
While both columns perform reproducibly under their
optimized conditions, separation conditions for the Acclaim Explosives
E2 can be readily changed to accommodate inclusion of additional
explosives compounds.
The manufacturing process is controlled to
ensure that every Explosives column delivers reproducible performance,
lot-to-lot and column-to-column. The columns are tested for baseline
resolution of all 14 explosives.
