Separations Products & Reviews

Separate a wide variety of polar analytes with a novel hybrid stationary phase

The Ultra line represents Restek’s broadest selection of stationary phases on a single silica support. Made of high-purity, type-B silica that minimizes activity and creates high-density bonding, these columns are designed for selective and reliable HPLC applications.

Include the most common consumable GC supplies and tools

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.

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

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!

Simplifies Clean-Up and Degassing of Mobile Phase Solvents and Other Solutions

Acrodisc PSF syringe filters are available in many membrane types, sizes, and packaging configurations to fit all applications.

Genius NM32LA Nitrogen Gas Generator for LC/MS applications.

YMC-Triart: Robust and reproducible (U)HPLC columns with a wide range of stability towards pH (1-12), temperature and 100% aqueous eluents.

Coated and immobilized CHIRAL ART polysaccharide columns by YMC offer wide selectivity range, high stability and attractive pricing.

Capillary columns available with every fully porous RP/NP/HILIC phase from YMC for high sensitivity analyses. Compatible with nearly all Nano-/MicroLC/MS systems due to two different connection sizes (1/16" and 1/32").  

Highly robust (U)HPLC columns for BioLC which are stable towards pH and temperature. Different pore sizes are available for the analysis of peptides, proteins, antibodies and oligonucleotides. 

A Complete Solution for Monitoring LC and MS Instrument Quality Control and Performance. In combination with an accompanying software tool, the 6 × 5 LC-MS/MS Peptide Reference Mix provides a convenient way to assess LC column performance and MS instrument parameters, including sensitivity and dynamic range. Consists of 30 peptides; 6 sets of 5 isotopologues of the same peptide sequence, differing only in the number o…

The ecTOF is the world’s first GC-HRMS with simultaneous acquisition of EI (Electron Ionization) and CI (Chemical Ionization) information in a single injection. While using EI as the gold-standard GC/MS ionization, the ecTOF in parallel operates a novel CI source. This way it simultaneously provides perfectly aligned accurate mass structural and molecular ion information within a single GC run.
