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…

With Raptor™ LC columns, Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC® technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation. SPP core-shell columns commonly employ traditional phe…

The 1515 Isocratic HPLC Pump is an isocratic pump that offers the same performance as the 1525 Binary HPLC Pump. It features and integrated, high-pressure binary pump with on-board pulse dampening and efficient mixing. Its pulse-free solvent flow with analytical to semi-preparative flow rates are well suited for high sensitivity detectors Designed for use with 2 to 4.6 mm I.D. columns in routine HPLC applications, the pump has…

Protein/Peptide Columns

LC/GC Certified vials are tested by LC/UV for residues of chemicals used in processing and packaging vials. The septa are tested by headspace GC to ensure low levels of low molecular weight polymer. These vials are suited for analyte concentration in the µg/mL concentration; typically detectors like UV and RI.

Most chromatographers have experienced problems retaining and separating polar compounds using conventional reversed-phase chromatography.  These difficult-to-analyze compounds either pass through the column unretained or, if retained at all, co-elute at the beginning of the chromatogram.  Waters AtlantisTM columns are designed for these types of challenging separations and are available in two chemistries: dC18 and HILIC sili…
