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

Designed specifically for semivolatiles (SVOC) analysis, Restek’s new Rxi-SVOCms columns are designed to provide consistent performance that will keep calibrations passing longer so more samples can be run before needing to recalibrate the instrument or replace the column.

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. The bonding mechanisms produce a col…

Restek's new line of fused silica capillary GC columns - Rxi® columns - is now available!  The columns are designed specifically to be the best columns available, for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity. In addition to outstanding performance, this combination of column characteristics assures Rxi® columns will have long lifetimes. The Restek chemists also have developed a sta…

- Optimized column selectivities guarantee resolution of ethanol, internal standards, and frequently encountered interferences. - Robust and reproducible column chemistry ensures longer column lifetime and consistent results. - 2 minute analysis time increases lab productivity. - Stable to 260 °C Don’t forget: Blood alcohol analysis requires dual column confirmation when using GC/FID.

Accurate boiling point determination for medium and heavy fractions using GC simulated distillation requires columns and phase polymers that are robust enough to withstand high temperatures without significant degradation. Metal columns are a better alternative than fused silica, and the MXT®-1HT SimDist columns are the lowest bleed, highest efficiency columns available, outperforming other metal columns for critical method p…
