As a distributor for Scientific Instrument Services we are able to offer a wide range of Consumables for Gas Cromatography & Mass Spectrometry.  Some examples are shown below but please visit the SIS Website for full details.

-- The only difference is the price.

Individually Tested

Each column receives individual rigorous testing to insure that columns meet the highest quality standards for resolution, retention characteristics, inertness, bleed and reproducibility.

High Temperature Limits

A unique automated processing allows VICI to produce columns exhibiting higher upper temperature limits. These improved upper temperature limits enhance column "bake out," reducing sample carryover and cycle times.

Low Bleed

VICI uses proprietary liquid phase processing to produce low bleed characteristics while maintaining identical retention characteristics to the phases you are used to. These processes combined with proprietary automated deactivation, coating, curing, bonding and crosslinking produce MS-certified bleed characteristics equal to the best. Be wary of competitors’ so-called "virtually identical" phases.

The ValcoBond Guarantee:

A automated process allows VICI to reproducibly manufacture the highest quality capillary columns at the lowest cost. VICI is so sure of it, they offer this no-risk guarantee: ValcoBond columns will exactly replace the equivalent competitors’ column for your application or your column is free!
