ValcoBond and ValcoPLOT capillary columns meet the highest quality standards for resolution, retention characteristics, inertness, bleed, and reproducibility. The ValcoPLOT line includes our unique HayeSep PLOT columns.
Our PDD (pulsed discharge detector) utilizes a stable, low-powered, pulsed DC discharge in helium as the ionization source, which yields performance equal to or better than conventional radioactive sources.
The microvolume, dual filament TCD is a stand-alone unit optimized for capillary chromatography and enhanced sensitivity at low flow rates.
The VICI column heating unit for fast GC is designed for precise temperature programming with rapid heating and cooling of a low mass nickel-clad or nickel-wire column. The column is resistively-heated by applying a low-voltage current to the column coating or wire.
The heating unit and column are included in our fast GC conversion kit for HP6890s and Agilent 7890s.
Contaminant traps and gas purifiers for specific gases dramatically reduce the levels of contaminants, enhance the purity of lower grade helium, and help ensure instrument stability and reproducibility while lowering maintenance costs.
