Overview
Capillary Column is a high-efficiency separation device featuring an internal diameter typically under 0.53 mm, fabricated from fused silica or stainless steel with a stationary phase coating applied to the inner wall.
Application
- Chemical Analysis: Gas chromatographs for petrochemical and environmental testing.
- Pharmaceuticals: HPLC systems for purity verification of active ingredients.
- Food Safety: GC-MS units detecting pesticide residues in processing lines.
Precautions
- Operate strictly within temperature limits of -60°C to 450°C and pressure below 10 bar.
- Avoid mechanical bending or thermal shock during installation.
- Perform regular conditioning cycles to remove contaminants and extend service life.
