Answer:The mid-polarity DB-624 phase is used for separations of volatile organic compounds.
Answer:The fused-silica column is 30 m × 0.53 mm × 3.00 µm on a five-inch cage.
Answer:The published operating range is −20 to 260 °C.
Agilent J&W DB-624 is a mid-polarity fused-silica GC capillary column designed for volatile organic compound separations. A 30 m length, 0.53 mm internal diameter and 3.00 µm stationary-phase film provide a wide-bore format with added retention of volatile components. The column is supplied on a five-inch cage and uses the DB-624 phase associated with USP G43 methods. The listed operating temperature range is −20 to 260 °C. Its thicker film and wide internal diameter differ from narrow-bore or thin-film DB-624 versions, so validated method conditions should match the correct configuration.
