Answer:DB-624 is a mid-polarity GC stationary phase used for volatile compounds and residual-solvent methods.
Answer:This 30 m × 0.25 mm × 1.40 µm version is wound on a 5-inch cage.
Answer:The listed temperature range is −20 °C to 260 °C.
Agilent J&W DB-624 is a mid-polarity fused-silica GC column used in methods for volatile organic compounds and residual-solvent analysis. This column combines a 30 m length and 0.25 mm internal diameter with a 1.40 µm bonded film and a compact 5-inch cage. Its 624-type phase provides retention and selectivity different from nonpolar DB-1 or HP-1 columns, supporting analysis of volatile mixtures with differing functional groups. The specified operating-temperature range is −20 °C to 260 °C. The 5-inch cage configuration should be matched to the receiving GC oven's physical column mounting requirements.
