A Trident in-line guard cartridge holder can be used with almost any HPLC column by connecting it with a short piece of 1/16" tubing, appropriate nuts and ferrules, or finger-tight fittings. The system can be used with Restek columns, or with columns from other manufacturers. Holders are...

Use this aluminum oxide powder to clean surfaces that contact the sample or ion beam when you encounter poor sensitivity and inadequate abundances at high masses.

low-polarity phase; Crossbond diphenyl dimethyl polysiloxane General purpose columns for drugs, solvent impurities, pesticides, hydrocarbons, PCB congeners (e.g., Aroclor mixes), essential oils, semivolatiles. Column specifically tested for low-bleed performance. Temperature range: -60°C to...

Universal PEEK connectors allow easy installation of all 1/16" tubing, including stainless steel, up to 5,000 psi.

Unique 3D radial design is not prone to face velocity effects and delivers higher uptake rates than standard 2D flat axial devices. Higher uptake rates give excellent low-level sensitivity, even for short sampling periods (down to 15 min). Higher capacity allows you to sample accurately up to 30...
