- 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…

Don't let a small leak turn into a costly repair—protect your analytical column by using a Restek leak detector. Audible tone indicates the severity of a leak. Redesigned circuitry offers 12 hours of operation between charges. Detects a broad range of gases; Ex rated for use with hydrogen and other explosive gases.

Switch to a Raptor HILIC-Si LC column when you need more retention and resolution of hydrophilic, polar analytes. HILIC silica column designed for increased retention of polar compounds without ion-pairing reagents. 2.7 μm Raptor core-shell particles provide the speed of SPP, with greater efficiency and capacity than 5 μm particles. Ideal for increasing sensitivity and selectivity in LC-MS analyses. Fully compatible with both…

For Shimadzu 17A, 2010, 2014, and 2030 GCs equipped with split/splitless inlets

Rtx-Wax columns are the most inert and efficient PEG columns currently available. The extended operating temperature range allows analysis of compounds having a wide volatility range and ensures low bleed at temperatures as high as 250 °C. Selectivity is comparable to other Carbowax columns for compounds of intermediate to high polarity.

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. This exceptionally stable C1 phase features our least-retentive reversed-phase hydrocarbon packing. Stationary Phase Category: trimethylsilane (L13) Ligan…

Certified reference materials (CRMs) manufactured and QC tested in  ISO-accredited labs  satisfy your ISO requirements.

Whether you need to replace system tubing as part of your troubleshooting or want to reduce the dwell volume of your system as you move to narrower columns, Restek has the quality tubing in the lengths and IDs you need. Each ID is color-coded, so it is easy to identify and replace correctly. Tubing is precision cut, resulting in clean, square-cut ends without ovality.

Extend column lifetime. Excellent inertness—obtain lower detection limits for active compounds. Sharper chromatographic peaks by utilizing retention gap technology. Maximum temperature: 360 °C.

3-IN-1 TECHNOLOGY with Rxi® columns: • Highest Inertness • Lowest Bleed • Exceptional ReproducibilityRxi® columns are more stable at high temperatures than any other manufacturer’s column, resulting in higher system sensitivity. This low-bleed characteristic is the result of superior stabilization achieved by optimizing polymer cross-linking and surface deactivation technologies. Benefits of using ultra-low bleed Rxi® column…

The world’s most advanced multi-detector GPC/SEC system

The most advanced tissue homogenizer

TSKgel Amide-80 and TSKgel NH2-100 HILIC columns from Tosoh Bioscience are first class columns when it comes to separations of hydrophilic compounds like peptides, carbohydrates, polar natural substances, amino acids, oligonucleotides, organic polar acids and bases, even proteins.

HPLC column

Widely considered the premium columns for analyzing biopolymers by GFC, TSKgel G2000SWXL, 5 μm columns are an excellent choice for small proteins and peptide separations.

The TSKgel Alpha-4000 column is packed with rigid, porous polymer beads which show minimal shrinkage or swelling in polar organic solvents (methanol, acetonitrile, DMSO, isopropanol, THF, and HFIP). This column is stable in a wide variety of organic solvents at concentrations up to 100%.

TOYOPEARL HW-55S resin is a hydroxylated methacrylic polymer for size exclusion chromatography

The TSKgel OligoDNA RP and TSKgel TMS-250 columns incorporate 5 μm or 10 μm spherical porous silica with 250Å pores to allow unhindered access by large oligonucleotides and proteins respectively.

TSKgel STAT columns were designed to increase throughput for high efficiency separations of biomolecules. The nonporous, hydrophilic base material provides superior performance at reduced analysis time.

Silica-based columns are stable and efficient but unsuitable for alkaline analyses due to the silica matrix's weakness under high pH. InertSustain C18, with its novel surface-modified silica, overcomes this limitation. It retains Inertsil's benefits—low back pressure, superior inertness, high efficiency, consistent performance, and wide solvent compatibility—while enabling analyses over a broad pH range.
