The ValcoBond® product line contains columns characterized by high temperature ranges and low bleeding. Vici Valco guarantees high quality, reproducible and reliable results. Examples of this product line include the columns VB-1 from 100% dimethylpolysiloxane, VB-5 from 5% phenylmethylpolysiloxane or VB-Wax, which consist of polyethylene glycol.
The columns of the line ValcoPLOT®, where PLOT stands for "Porous Layer Open Tubular", are characterized by a unique HayeSep phase. This phase reduces the running time and increases the water tolerance, which means that a wide polarity range is available. HayeSep columns consist of different stationary phases and thus offer a wide range of possible applications.
VP-alumina columns serve to analyze C1-C5 hydrocarbon fragments and thus replace the use of cryoscopic methods for their analysis. The stationary phase is deactivated by small salt crystals and is stable up to temperatures of 200 ° C. Potassium chloride produces an apolar phase, while sodium sulfate produces columns that have an increased retention of unsaturated hydrocarbons.
