Chromatographic Specialties Stainless Steel Packed GC Column, 8 ft x 1/8 in, 20% OV-101 on PAW-DMCS 80/100, Preconditioned, Lot of 2

This lot includes two preconditioned stainless steel packed columns from Chromatographic Specialties Inc., designed for gas chromatography (GC) applications. Each column measures 8 feet in length with a 1/8-inch outer diameter, packed with 20% OV-101 (a non-polar dimethylpolysiloxane stationary phase) on Chromosorb PAW-DMCS support (80/100 mesh), which is acid-washed and silanized for enhanced performance. These columns are ideal for separating non-polar compounds such as hydrocarbons, pesticides, and steroids in industries like pharmaceuticals, environmental testing, and petrochemical analysis. Key features include high thermal stability up to 325°C, excellent inertness due to the DMCS treatment, and preconditioning to minimize bleed and ensure immediate usability. Advantages over similar products include better peak symmetry for polar analytes and durability in high-temperature operations compared to glass columns. Drawbacks may include higher cost than capillary columns and potential for lower resolution in complex mixtures. Based on image analysis, the columns appear new or unused, coiled for compact storage, with no visible damage. For optimal use, pair with compatible GC systems like those from Agilent or Shimadzu.
