Product news

Dionex Corporation is pleased to announce the addition of new Acclaim® Carbamate columns designed for analysis of carbamates specified in United States Environmental Protection Agency (US EPA) Method 531.2, using LC-postcolumn derivatization-fluorescence or LC-MS methods.

Carbamates are widely used as pesticides for food crops worldwide. The residual carbamates can pollute drinking water sources, thus causing environmental and health concerns. Under the Clean Water Act, the US EPA requires that drinking water and raw surface water be monitored for the presence of carbamate pesticides and related compounds as described in US EPA Method 531.2 using HPLC with postcolumn derivatization. Detection of regulated compounds, at ever decreasing levels, is a challenge faced by many water testing laboratories. Very often, LC-MS is required for higher sensitivity and identification.

Dionex Acclaim Carbamate columns have the following features:

• Baseline separation of carbamate pesticides in EPA Method 531.2
• Compatible with postcolumn derivatization and LC/MS methods
• High column efficiency
• Rugged column packing

The Acclaim Carbamate columns include 3 μm particle size in 2.1 x 150 mm, 3.0 x 150 mm, and 4.6 x 150 mm formats, and 5 μm particle size in a 4.6 x 250 mm format.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems. Find the best UHPLC and HPLC equipment in our peer reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.
