SEC-MALS Detector
Based on Wyatt Technology’s legacy of multi-angle light scattering (MALS) detectors, the DAWN HELEOS-II is the MALS detector with the greatest sensitivity for absolute molecular weight and size determinations of polymers and biopolymers in solution. The DAWN may be connected in series to any chromatographic system in order to determine absolute molar masses without the use of reference standards or column calibration.  Learn more |

Gulf of Mexico Research Initiative Grant Competition
The Gulf of Mexico Research Initiative (GoMRI) has announced plans to invest up to $105 million between 2015 and 2017 to support research consortia investigating the effect and impacts of hydrocarbon release into the environment. The funding will be awarded to four or more institutions over two years, under the programme known as RFP–IV. GoMRI report that each team will be funded between $1 million and $7.5 million each year.

Methamphetamine Analogue Found in Dietary Supplement
Potentially dangerous levels of the methamphetamine analogue, N, α ‑diethyl‑phenylethylamine (N, α -DEPEA), have been detected in a widely available dietary supplement using ultrahigh-pressure liquid chromatography coupled to mass spectrometry (UHPLC–MS). The supplement, Craze, can be bought in the USA and from on-line retailers. The findings have been published in the journal Drug Testing and Analysis by a team of scientists from Harvard Medical School (Massachusetts, USA), NSF International (Missouri, USA), and the National Institute for Public Health and the Environment Health Protection Center (Bilthoven, The Netherlands).1 More... |
