Identification of Synthetic Colorants Using HPLC-DAD and Chemometrics
April 20th 2016A team of researchers from the State Laboratory of Chemo/Biosensing and Chemometrics in China has developed a novel high performance liquid chromatography-diode array detection (HPLC-DAD) method for the identification of six synthetic colours in five beverages.
Tips & Tricks GPC/SEC: Flow Marker — An Easy Concept to Increase Reproducibility
April 11th 2016Experienced gel permeation chromatography/size-exclusion chromatography (GPC/SEC) users know that equilibration of the columns takes much longer than the time needed by the pump to produce a constant flow. An analysis in this phase would clearly yield different results from those achieved after complete equilibration of GPC/SEC columns. Furthermore, false but constant flow rates affect the molar masses derived from a GPC/SEC calibration curve. An internal flow marker can help to increase reproducibility and accuracy of GPC/SEC results.
Trajan Scientific Acquires LEAP Technologies
April 11th 2016Trajan Scientific (Melbourne, Australia), which develops medical devices as well as analytical systems such as gas and liquid chromatography columns and sample preparation systems, has acquired the business of LEAP Technologies (Carrboro, North Carolina).
Low-Pressure GC and UHPLC Analysis of Environmental Contaminants in Meats
April 11th 2016A team of researchers has developed a high‑throughput analysis method for 192 diverse pesticides and 51 environmental contaminants in cattle, swine, and poultry meats. The team used a combination of low-pressure gas chromatography coupled to tandem mass spectrometry (LP)GC–MS–MS and ultrahigh-pressure liquid chromatography coupled to tandem MS in the analysis.
Characterizing New Psychoactive Substances
April 11th 2016Researchers from the Joint Research Centre of the European Commission have published a case study detailing the characterization of new psychoactive substances using gas chromatography–mass spectrometry, nuclear magnetic resonance, high‑resolution tandem mass-spectrometry, and Raman spectroscopy.
