Silylation Grade Solvents Thermo Scientific™

Use specially manufactured and packaged Thermo Scientific™ Silylation Grade Solvents to meet the exacting needs of silylation and other sensitive derivatization reactions. They are purified, dried, and packaged under nitrogen in convenient Thermo Scientific™ Hypo-Vial™ Sample Storage Vials, and are supplied with elastomer septa to enable immediate access to the sample without exposure to moisture and oxygen. Use polar solvents (acetonitrile, dimethylformamide, dimethylsulfoxide, pyridine, tetrahyrdrofuran) to facilitate reactions; nonpolar organic solvents may be used but will not accelerate the rate of reaction.

BSA Silylation Reagent Thermo Scientific™

Derivatize analytes quickly and quantitatively under mild conditions using Thermo Scientific™ BSA Silylation Reagent. This reagent reacts readily with a wide range of compounds, including alcohols, amines, carboxylic acids, phenols, steroids, biogenic amines, and alkaloids to form volatile, stable TMS derivatives for GC.

Dionex™ 0.5M Sodium Bicarbonate Anion Eluent Concentrate Thermo Scientific™

Designed as an aid to methods development or for changing applications requirements, this ready-to-dilute Thermo Scientific™ Dionex™ 0.5M Bicarbonate Anion Eluent Concentrate enables you to make different sodium carbonate/bicarbonate eluent concentrations, quickly and easily. The concentrate, provided in 500mL quantities, is made with only high purity, reagent grade chemicals and water (18 MO-cm) and quality checked for ionic contamination. You can use this concentrate in conjunction with the Dionex 0.5M Carbonate Eluent Concentrate for custom eluent concentrations.

Dionex™ Trichloroacetic Acid Internal Standard, 1000 mg/L Thermo Scientific™

Simplify the challenge of determining haloacetic acids (HAA) in drinking water with these convenient, pre-prepared standards IC analysis to meet U.S. EPA required minimum contamination levels. Designed to save time and eliminate errors in standards preparation, you can rely on Thermo Scientific™ Dionex™ Haloacetic Acid Internal Standards for purity and quality.

BSTFA Silylation Reagent Thermo Scientific™

Improve GC analysis with Thermo Scientific™ BSTFA Silylation Reagent. The highly volatile byproducts mono(trimethylsilyl)trifluoroacetamide (BSTFA) and trifluoroacetamide elute with the solvent front to ensure excellent chromatographic separations. This silylation reagent reacts with a wide range of polar compounds and is particularly well suited for the GC analyses of some lower boiling TMS-amino acids and TMS Krebs cycle acids.

TMCS Silylation Reagent Thermo Scientific™

Catalyze the derivatization of difficult-to-silylate compounds using Thermo Scientific™ TMCS Silylation Reagent. It is an excellent adjunct for forming TMS ethers for GC determinations. TMCS is also useful for preparing TMS derivatives of organic acids.

BSTFA + 1% TMCS Silylation Reagent Thermo Scientific™

Use Thermo Scientific™ BSTFA + 1% TMCS Silylation Reagent for analytes that are difficult to silylate. Stronger than BSTFA alone, this catalyzed formulation is ideal for derivatizing compounds such as fatty acid amides and slightly hindered hydroxyls for GC analysis.

Dionex™ AS14 Eluent Sodium Carbonate/Bicarbonate Concentrate (100X) Thermo Scientific™

A convenient, ready-to-dilute Thermo Scientific™ Dionex™ AS14 Eluent Concentrate; Sodium Carbonate/Bicarbonate Concentrate for use with Dionex™ IonPac™ AS14 Anion-Exchange Columns, which perform fast analysis of inorganic anions in complex sample matrices. Use this eluent concentrate together with Dionex™ Combined Seven Anion Standard.

Dionex™ MMS Regenerant Concentrates Thermo Scientific™

Increase productivity and provide reliable analyses with Thermo Scientific™ MMS Regenerant Concentrates.

Methylate Reagent (DMFDMA) Thermo Scientific™

For easy, effective preparation of methyl esters from fatty acids and amino acids use Thermo Scientific™ Methylate Reagent (DMFDMA). Reactions are typically complete upon dissolution (except for long-chain solid acids) and quantitative yields are obtained when reagent and sample are injected without prior mixing. No water washing, extraction, or concentration of derivatives is required and no water is formed. Methylate Reagent (DMFDMA) contains 2 mEq/mL in pyridine and is supplied in ready-to-use Thermo Scientific™ Hypo-Vial™ Sample Storage Vials.

Dionex™ DCR Displacement Chemical Regeneration Reagents Thermo Scientific™

Use Thermo Scientific™ Dionex™ DCR Displacement Chemical Regeneration Reagents to prepare regenerants from concentrates when operating your ion chromatography (IC) system in DCR mode. DCR is an easy-to-use mode of operation for chemical suppressors that uses effluent from the conductivity cell to drive the regenerant into the regenerant chamber of the suppressor in a closed bottle configuration. DCR reagents are available as an anion regenerant concentrate (2N H2SO4) and a cation regenerant solution (2.06M TBAOH) in single or 4-pack bottles.

Dionex™ AS22 Eluent Concentrate; Sodium Carbonate/Bicarbonate Concentrate (100X) Thermo Scientific™

For fast, reliable eluent preparation, the ready-to-dilute Thermo Scientific™ Dionex™ AS22 Eluent Concentrate; Sodium Carbonate/Bicarbonate Concentrate will save you time and eliminate potential contamination and preparation error. For use with Dionex™ IonPac™ AS22 columns, simply prepare eluent by dissolving the concentrate in deionized water. The 250mL of 100x concentrate is made with only high purity, reagent grade chemicals and water (18 MO-cm) and quality checked for ionic contamination. Concentrations of 0.45M carbonate and 0.14M bicarbonate are verified.

Dionex™ Eluent Regeneration Consumables Kits Thermo Scientific™

Thermo Scientific™ Dionex™ Eluent Regeneration Consumables Kits are available for both Anion or Cation Reagent-Free IC systems with Eluent Regeneration.

Dionex™ ERD™ 500 Electrolytically Regenerated Desalter Thermo Scientific™

Collect oligosaccharide fractions with less effort and with automated pH reduction and salt removal from high-pH eluents during ion chromatography (IC). The Thermo Scientific™ Dionex™ ERD™ 500 Electrolytically Regenerated Desalter removes sodium ions (Na+) from alkaline sodium acetate effluent in line, such as after high pH anion-exchange chromatography with pulsed amperometric detection (HPAE-PAD).

Dionex™ Kit of Standards for OQ/PQ Measurements Thermo Scientific™

The Thermo Scientific™ Dionex Kit of Standards is used for performance validation in ESI and APCI modes.
