Gas Chromatography Columns. Two types of columns are used in gas chromatography: packed columns and capillary columns. Short, thick columns made of glass or stainless steel tubes, packed columns have been used since the early stages of gas chromatography.

DB-624 Ultra Inert (UI) column is optimal for the fast & accurate analysis of volatile organic compounds (VOCs) in pharmaceutical, environmental, food, and industrial chemical applications by GC and GC/MS.

Abstract. High performance liquid chromatography (HPLC) is an important qualitative and quantitative technique, generally used for the estimation of pharmaceutical and biological samples. It is the most versatile, safest, dependable and fastest chromatographic technique for the quality control of drug components.

GC columns contain a stationary phase, typically a polymeric material. It is through the interaction between the analytes and this stationary phase within the column that separation of the analyte into their molecular components can occur. There are two types of GC columns: packed columns and capillary columns.

Rtx-624 Columns Temperature range: -20 °C to 240 °C. Equivalent to USP G43 phase.

Conventional LC columns are 100?300 mm long with outer diameter of 6.4 mm (1/4 inch) and internal diameter of 3.0?4.6 mm. For applications involving LC?MS, the length of chromatography columns can be shorter (30?50 mm) with 3?5 ?m diameter packing particles.

DB-1 GC Columns J&W DB-1 is nonpolar and low-bleed GC column that operates under high temperature limits. DB-1 is an excellent choice for general purpose use in a wide variety of applications. Precision-engineered DB-1 is bonded, crosslinked and solvent rinseable, and is equivalent to USP phase G2.
