Restek Corp. Products & Reviews

for Agilent GCs with 5971/5972, 5973, 5975, or 5977 GC-MS  

General purpose columns for FAMEs, flavor compounds, essential oils, solvents, xylene isomers, and US EPA Method 603 (acrolein/acrylonitrile). Resistant to oxidative damage. Temperature range: 40°C to 260°C. Equivalent to USP G14, G15, G16, G20, and G39 phases. The polar-deactivated surface tightly binds the Carbowax® polymer and increases thermal stability, relative to competitive columns.

Restek's new line of fused silica capillary GC columns - Rxi® columns - is now available! 

3-IN-1 TECHNOLOGY with Rxi® columns

Rxi® fused silica capillary GC columns were designed specifically to be the best columns available, for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity.

Restek's former Rtx®-17 columns are now manufactured using new Rxi® column technology--for unsurpassed inertness, ultra-low bleed, guaranteed reproducibility, and unmatched performance!

Accessory for Agilent 5972, 5973, 5975, or 5977 GC-MS. EI (electron ionization) filaments meet or exceed original manufacturer's performance. Every filament is subjected to QC tests, including heat, electrical current, and resistance. Samples from each filament manufacturing lot are installed in an MSD for in situ testing.
