The humble blowfly could lead to better detection of methamphetamine (MA) in decomposing tissue. Research has explored the effect of MA on the development, growth rates and survival of the blowfly in relation to estimating post-mortem intervals.
A new study identified specific phenolic compounds found in the petals of indigenous rose species and compared them with the phenolic profiles of modern rose cultivars to determine differences in the makeup of roses traditionally used for medicinal purposes and those varieties cherished for aesthetic qualities.
Years after the 2010 Deepwater Horizon Oil spill, as oil continues to wash ashore as "sand patties" and persists in salt marshes abutting the Gulf of Mexico, questions remain about how much oil has really been deposited on the seafloor.
Surface catalysts are notoriously difficult to study mechanistically, but scientists have shown how to get real-time reaction information from Ag nanocatalysts that have long frustrated attempts to describe their kinetic behavior in detail.
New research reveals how the algae behind red tide thoroughly disables– but doesn’t kill– other species of algae. The study shows how chemical signaling between algae can trigger big changes in the marine ecosystem.
New research shows that enormous lakes that existed in the western U.S. during the peak of the last Ice Age grew large because of a cooler climate and a reduced evaporation rate. The finding could help improve computer simulations of climate change.
Torrey Pines Scientific’s EchoTherm Model CO50 Programmable HPLC Column Chiller/Heater has a temperature range of 4.0 to 100.0 C readable and is settable to 0.1 C. The PID control software regulates temperatures to ±0.2C, even at ambient.
Thermo Fisher Scientific’s SOLAµ solid phase extraction (SPE) micro elution plates meet the growing trend in bioanalysis toward higher levels of sensitivity and reproducibility with decreasing sample volumes. Using SOLA SPE technology, the plates are designed to deliver robust, reproducible processing at elution volumes as low as 25 µL.
SGD’s high capacity gas purifier housing Model 8000A features a rated operating pressure of 1500 psig. It is constructed of a machined aluminum shell that accepts a high-capacity replaceable cartridge.
Restek has expanded its comprehensive selection of cannabinoid-related reference standards by adding cannabidiolic acid (CBDA, cat no. 34094). This diluted standard is DEA-exempt, so there's no need to purchase costly neat materials or make your own standards, and it is prepared in acetonitrile, which helps maintain stability by preventing methylation of the carboxylic acid group on the molecule.
Molex has developed a Polymicro Technologies Capillary Configurator design program for the selection of simple to complex capillary tubing products. The free, online program guides users in identifying and submitting product specifications and application parameters, which are reviewed by the technical team.
Markes International has improved its SafeLok TD sampling tubes. The tubes can be used interchangeably with standard tubes. They have the same external dimensions and sorbent masses, but are protected with diffusion-locking technology at both ends, which stops contaminants getting in and analytes getting out.
JM Science’s Tri-Fitt fittings for high pressure UHPLC and HPLC applications require no leaks at pressures at or above 20,000 psi. The fittings kit is designed with three separate parts—a black carbon-PEEK ferrule, a stainless steel triangular ferrule and a stainless steel nut.
The INFICON CMS5000 Monitoring System provides continuous, unattended remote monitoring of water or air. Using GC technology, the systemn analyzes and quantifies volatile organic compounds (VOCs) and toxic industrial chemicals (TICs)—such as 4-methylcyclohexane methanol, BTEX, methyl tert-butyl ether, trichloroethylene, and trihalomethanes—on-site for accurate results in min.
DataApex has released a control driver for Symbiosis Technology Components manufactured by Spark Holland BV. Symbiosis sample preparation components include: SPARK HPD (high pressure dispenser), SPARK ACE (automatic cartridge exchanger), SPARK U HPLC SPH1240 (HPG pumpset), SPARK Mistral (column oven) and SPARK Alias (autosampler) instruments.
BUCHI’s PrepChrom C-700 chromatography system combines flash chromatography with preparative HPLC. Bridging the gap between them, the system sets a new standard for purification of synthesis mixtures or complex natural extracts.
Waters Corp. has expanded its family of CORTECS Columns with 2.7-um silica-based, solid-core particle columns for HPLC column performance. Designed for analytical scientists who need to maximize performance on their existing LC systems, the 2.7-um columns run at lower pressures while delivering high efficiencies.
Diamond Analytics’ vFLARE columns offer unique selectivity and expand the existing range of analytical capabilities in separation science using diamond-based technology, which allows for research into new areas of HPLC methods development. The columns are based on a porous nano-diamond core shell support.
Phenomenex’s Kinetex Core-Shell Biphenyl HPLC/UHPLC columns give researchers the ideal orthogonal selectivity to traditional C18 phases. This phase is suited for a broad range of complex-mixture analyses in clinical research and forensic toxicology, food and environmental testing, and pharmaceutical, bioanalytical and DMPK studies.
W. R. Grace & Co.’s ProVance pre-packed Protein A columns are a high-performance disposable chromatography solution to help meet the growing demand for downstream purification. Increasingly, biopharmaceutical companies are shifting to single-use manufacturing for greater portability, scalability and rapid deployment of biologics.
