Chromatography & Spectroscopy Reagents

Spectrum obtained by splitting of white light through glass prism

Analytical reagents are chemical compounds or mixtures intended for qualitative and quantitative analytical testing. They must comply with the highest international standards and show maximum purity and minimum impurities. We offer a wide selection of analytical reagents for different techniques such as wet chemistry, chromatography, spectroscopy, electrochemistry, titration, and water quality control. Our selection, includes high-purity acids, bases, solvents, and specialty reagents, such as ionophores and derivatization reagents for a wide spectrum of analytical applications. Our reagents have purity grades ranging from ACS Reagent Grade to high purity, for ultra-trace analysis.

Reagents for ion pair chromatography

Our selection of ion-pair reagents includes tailor-made compounds for the determination of cationic and anionic analytes.

  • Quaternary ammonium salts with alkyl substituents of different chain lengths for the analysis of acids or anions.
  • Strong acids such as straight-chain alkyl sulfonic acids for base or cation analysis

Our reagents are subjected to rigorous quality control testing, including UV-absorption testing, filter testing, redox testing, and HPLC gradient grade testing to guarantee their quality and performance in your application.

Derivatization Reagents

Derivatization is used in chemical analysis to convert an analyte into a product that improves separation and enhances method sensitivity. This technique enables the analysis of compounds that are otherwise not volatile or stable enough for analysis by GC, GC-MS, HPLC, or LC-MS.

We offer a comprehensive portfolio of derivatization agents for various chromatography applications, including reagents for silylation, acylation, alkylation, and esterification suitable for GC, HPLC, and TLC chromatography and accessories.

Reagents for Electrochemistry

Our Selectophore™ product line can be used to prepare sensor membranes for ion-selective and optical devices.

We also offer accessories, additives, buffers, chromoionophores, electrolytes, ion standard solutions, ionic strength adjustor solutions (ISA), ionophore cocktails, plasticizers, polymers, ready-to-use membranes, silanizing agents, and solvents for ion-selective electrode preparation.

Reagents for Spectroscopy

Analytical spectra are influenced by the purity of solvents and reagents used in sample preparation. Our high-purity reagents are designed to offer reliable and accurate results, while eliminating the need for repeat analyses.

  • Optical and chemical purity with batch-to-batch reproducibility
  • Produced using premium-quality raw materials and subjected to stringent purification procedures
  • No trace of UV, IR, or fluorescence active components

Our comprehensive portfolio of spectroscopy materials includes reagents for analyses by different techniques such as fluorescence/luminescence spectroscopy, nuclear magnetic resonance spectroscopy, infrared (IR) spectroscopy, and UV/Visible (UV/Vis) spectroscopy.
