500 g, cation exchange resin, sodium form, 1% crosslinkage, 50–100 dry mesh size, 300–1,180 µm wet bead size, ~3,500 MW limit

Measure trace bromate and other oxyhalides in drinking water, ground water, wastewater, and other diverse sample matrices with the Thermo Scientific™ Dionex™ IonPac™ AS23 carbonate eluent anion-exchange column.

The Ceres Nanosciences Nanotrap® Protein particles utilize affinity capture and size exclusion to attract and bind low abundance proteins, while excluding unwanted high abundance and high molecular weight interfering molecules.

An automatic polarimeter ideal for food, beverage, university and contract laboratories

Advantage Pre-Scored Round Well Cap Mats with Molded Silicone/PTFE Liner for Standard 96 Position Collection Plates

An ODS column with Anion and Cation Exchange. Weak ionic ligands adequately bonded to this material optimized for the separation of basic/acidic compounds at neutral pH.

A Rapid Solid Phase Extraction (SPE) Solution

In HPLC analysis, especially in gradient elution, some unexpected peaks, which are usually called Ghost peaks, may appear in a chromatogram. Ghost peaks my appear for many reasons, including residual in injection valve, water pollution impurities and unknown components in sample. Generally, they are caused by impurities from mobile phase. Welch Ghost-Buster Column can solve this problem easily! Welch Ghost-Buster colu…

The only high-purity gas that guarantees minimal impurities.

High-end imaging and documentation system for white light and UV fluorescence detection

Application of up to 75 samples as bands onto HPTLC glass plates (20 x 10 cm).

The visionCATS software organizes the workflow of the HPTLC analysis, controls the CAMAG instruments, and manages data evaluation.

Integrated FAST valve and precision micro peristaltic pump

At-line cell culture media analysis. Results on 30+ components in under 10 minutes. When and where is your call. With the REBEL, now is always on the table.

Immunoaffinity Columns for the Aflatoxins B1, B2, G1 and G2

Inlet base seals for Agilent gas chromatography.

Valco GC valves have been in almost all commercially-produced gas chromatographs from the time that valves originally began to replace other injection methods. New designs are smaller and easier to service, but still exhibit the quality and value that made them the industry standard. Medium temperature GC valves have a rotor made of Valco E, a polyaryletherketone/PTFE composite. High temperature GC valves use a polyimide/PT…

This Snap-N-Spike® reference solution is suitable for use in urine drug testing, clinical toxicology, or forensic analysis by LC-MS/MS or GC/MS.

NANOCHEM® WK-Series (White Knight™) purifiers offer the highest lifetimes and the best impurity removal efficiencies in a very economical design. The in-line design enables a very compact footprint and allows drop-in replacement of competing hardware designs.  WK-Series are available in a number of sizes ranging from 55-ml for point-ofuse applications to 9-liters for bulk gas purification. Flow rates range from 3 slpm (0.2 NM3…

The Alliance™ HPLC System is the flexible and reliable workhorse that meets your fundamental HPLC separation requirements.

Coupling TLC plates with mass spectrometry (TLC-MS) is a new field of high interest in planar chromatography. One particular advantage of TLC-MS is the flexibility it offers in the choice of mobile phases for separations. In comparison, HPLC-MS coupling does not allow the use of certain mobile phases, such as inorganic buffers.

Count on the Waters Arc™ HPLC System for high-efficiency separations and quality data to help meet your regulatory requirements with confidence.  The Arc HPLC system allows you to easily replicate and improve the performance of existing LC methods without compromising data quality.
