Application Specific GC Columns: Select FAME is tuned for optimal cis/trans separations of FAMEs, especially the C18 isomers. This low-bleed, bonded column has an isothermal maximum operation temperature of 275 °C and a programmed temperature of 290 °C—a dramatic improvement of 50 °C compared to nonbonded columns. Even though this is a very polar column, its efficiency is extremely high. Columns up to 200 m are available for detailed analysis of the C18:1 isomer cluster. This column also offers three times greater loadability, further improving the shape and separation for FAME isomers, especially if one component is present at a higher concentration.
P-Wax for Volatile Amines and Diamines GC column
CP-Wax 51 for Amines is designed for the analysis of C4–C10 amines, diamines, and aromatic amines. The column conforms to EPA method 607.
Select Permanent Gases/CO2 is a set of two parallel columns that combines CP-Molsieve 5Å for permanent gas analysis and CP-PoraBOND Q for CO2 analysis. Column dimensions meet the need for fast separation, lowest level analysis, and quantification of argon/oxygen. This column separates permanent gases and CO2 in a single run. Columns are coupled and tested.
Application Specific GC Columns: Select Al2O3 MAPD is an aluminum oxide PLOT column for the analysis of reactive hydrocarbons, specially targeted towards methyl acetylene and propadiene (MAPD). The column is stable up to 200 °C for hydrocarbons up to C10. Adsorption and nonstable response for reactive hydrocarbons are greatly improved; the column delivers up to a two-fold higher response for MAPD, which is particularly important when running impurity analyses.
VF-1301ms ultra-low-bleed columns have a similar selectivity to VF-624ms and are suitable for the analysis of semivolatile organic solvents, as well as PCBs and pesticides. Enhanced selectivity for USP 467 eliminates co-elution of benzene and 1,2-dichloroethane.
VF-1701 Pesticide Column is a highly inert and ultra-low bleed column, specially designed for the determination of trace levels of pesticide residues with ECD or MS detection. Every column is individually tested before shipment with key pesticides, including endrin and aldrin, ensuring optimal performance and consistency of results.
Application Specific GC Columns: • Specially designed for the determination of trace levels of pesticide residue • Highly inert for enhanced ECD and MS detection • Tested with key pesticides, including endrin and aldrin, for optimal performance and consistency of results • Low bleed • Tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency • Performance Summary shipped with each column
Select biodiesel GC column for glycerides UltiMetal,with retention gap
Application Specific GC Columns: • Complete set of biodiesel columns for full compliance and ease-of-use • UltiMetal deactivation technology for stainless steel tubing provides high accuracy and longevity • Pre-tested for complete confidence in results • Good column lifetime when operating at temperatures up to 400 °C • UltiMetal deactivated stainless steel column with ultra stable stationary phase • Convenient pre-coupled retention gap that is leak tested • Tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency • Performance Summary shipped with each column

VF-5ht Ultimetal improves the analysis of high-boiling compounds through low-bleed performance, even at high temperatures. Based on ultra-low-bleed technology, VF-5ht provides unmatched selectivity, sensitivity, and accuracy for the analysis of high molecular weight compounds. This column has temperature limits of –60 to 450 °C.
These configurations include a 2m UltiMetal retention gap that is pre-connected to the VF-5ht UltiMetal column with a high temperature column connector upon delivery.
Low Bleed GC/MS Columns. VF-624ms (along with VF-1301ms) is the world's first ultralow-bleed mid-polar 6% cyanopropyl/phenyl, 94% polydimethylsiloxane GC column. It eliminates co-elution of benzene and 1,2-dichloroethane and is designed to provide more accurate trace analysis of semivolatile organic solvents according to EPA methods 524, 624, and 8260, as well as USP 467.
VF-1701ms is an ultra-low bleed, 14% cyanopropyl/phenyl, 86% PDMS column for pesticides, PCBs, and semivolatile organic compounds (SVOCs). Improved phase technology delivers increased inertness and reduced bleed, resulting in more accurate trace analysis. High inertness makes it ideal for difficult analytes such as p,p’-DDT.
