Product Category
HK-5 Fused Silica Capillary Column
HK-5
- 95% Dimethyl-5% diphenyl polysiloxane, bonded crosslinked phase
- The most versatile and widely used stationary phase in the field of gas chromatography.
- It exhibits characteristic affinity for compounds containing aromatic rings.
- It exhibits excellent thermal stability and chemical inertness, making it suitable for the analysis of both acidic and basic compounds.
- An ideal choice for environmental analysis: dioxins and polychlorinated biphenyls (PCBs) Polychlorinated terphenyls (PCTs), polycyclic aromatic hydrocarbons, phenols, herbicides, organochlorine and organophosphorus pesticides, aromatic hydrocarbons, solvents, pharmaceuticals, oils, and others.
- This chromatographic column meets the requirements of USP G27 and USP G36 standards.
