The Wyatt Technology ViscoStar viscometer is an online chromatography detector for determining specific and intrinsic viscosities. The ViscoStar is claimed to have at least two times the signal-to-noise of products available on the market as well as a proprietary Transducer Protection System (TPS) that prevents accidental damage to sensitive transducer membranes.
The TEI 5805 II air analyser is a portable organic vapour meter with photo ionisation detection for broad spectrum gas detection and measurement. It can measure a wide variety of chemicals: process equipment leak detection; leaking underground storage tanks; head space measurement; and detection of contaminated soil and water.
The toxicity of trace elements in the environment is in many cases dependent on the chemical form in which they occur. Total element concentrations no longer provide sufficient information to allow risk-based toxicity assessments
The Coulter LH 500 haematology analyser is designed for mid- to high-volume clinical laboratories. It provides complete blood counts (CBC) with five-part differential analysis, including white blood cell, red blood cell, platelet and reticulocyte counts.
Using sophisticated computer algorithms running on standard desktop computers, researchers have designed and constructed a novel functional protein that is not found in nature. The achievement should enable researchers to explore larger questions about how proteins evolved and why nature 'chose' certain protein folds over others.
Due to the presence of residual acidic silanol groups in most commercial packings, secondary chromatographic effects are common and are usually troublesome. As a result, efficiency and peak shape for some analytes are usually unacceptable at neutral pH
A complete molecular-scale picture of how plants convert sunlight to chemical energy has been obtained at Purdue University in the US, offering potential new insights into animal metabolism as well.
Manufacturing processes of pharmaceutical tablets may change the morphology of the crystalline state of the active pharmaceutical ingredients (API) or the excipients
A University at Buffalo chemist has developed a new, high-throughput method for obtaining nuclear magnetic resonance data that can potentially performing orders of magnitude faster than conventional methods
Small, irregularly shaped samples can present difficulties for the established methods of metal analysis. Laser-ablation ICP-MS offers accuracy and precision independent of sample form
Alltech ELSD 800 is an evaporative light scattering detector that can add universal HPLC detection to any LC system to replace or complement existing detectors. The ELSD's universal response gives a closer representation of sample mass than UV detectors, making quantification more accurate when standards are not available. It can be used in parallel with MS to obtain maximum structural and concentration information for each sample. Unlike RI detectors, the ELSD offers high sensitivity, equilibrates quickly and is gradient compatible.
The Scentograph Plus II portable gas chromatograph features dual detectors, dual sequential column, internal carrier gas and calibration tanks and capillary injection port. Accessories including the dual sampling purge and trap or stack gas sampler allow the instrument to produce laboratory quality results at on-site locations.
