The LCGC Blog: The Heat is On! Insights into a More Logical Approach to GC Temperature Program Development
When the goal is to improve the effectiveness of GC method development, a little help can go a long way. In the latest installment of The LCGC Blog, Tony Taylor offers expert advice on GC temperature program development, highlighting the thinking behind establishing the major parameters with the GC temperature program. More...
Convert from Helium to Hydrogen as a GC Carrier Gas
Learn how to convert from Helium to Hydrogen as a GC carrier gas, Hydrogen is much less expensive, can provide more rapid separations at lower temperatures than Helium, and provides longer column life. Hydrogen gas is obtained by the electrolysis of water and many laboratories supply it to the GC via an in-house H2 generator. DOWNLOAD this easy to use STEP by STEP Guide.

Biotage Opens New Manufacturing Plant in South Wales
Biotage (Uppsala, Sweden) has opened a new manufacturing unit in Ystrad Mynach, South Wales, with the support of the Welsh Government. As part of the expansion at the South Wales site, an instrument-manufacturing unit has been moved from Boston, USA. Thanks to a grant from the Welsh Government, the company secured the use of a 825 square meter facility near to their existing premises and converted the area into a manufacturing line and offices.

Mummified Snacks
The ancient Egyptians embalmed meat mummies as an afterlife snack in the same way as their dead, according to the findings of a gas chromatography–mass spectrometry (GC–MS) analysis. The team from the University of Bristol (Bristol, UK) and the American University in Cairo (Cairo, Egypt) collaborated to analyze the chemical compositions of samples and tissues from meat mummies excavated by the Cairo Museum and the British Museum.

Designer Cannabinoids
The variance in the toxic effects of designer cannabis drugs marketed throughout Europe and the USA as “K2” or “Spice” could be the result of stereoselective metabolism of enantiomers by lung and liver enzymes, according to a study published in Analytical Chemistry. Chiral liquid chromatography–tandem mass spectrometry (LC–MS–MS) was applied to the analysis of JWH–018 and AM2201 metabolites in human urine. More...
Waters introduces the ACQUITY QDa Detector
The future is now separated from the past. Imagine a lab where all analytical scientists can acquire high-quality mass spectral data. On their own. Within their existing workflows. Across every sample. Without training. Waters imagined just that and introduces the ACQUITY QDa Detector. Click Here
Early Use of Chili in Mexico
Residues of chili pepper (Capsicum) have been found on pottery dating back 2000 years in southern Mexico, according to a study published in PLOS ONE.1 The New World Archeological Foundation (NWAF) first excavated the pottery (thought to date from 400 BCE–300 CE) from Chiapa de Corzo between 1955 and 1963. Ultrahigh-pressure liquid chromatography coupled to tandem mass spectrometry (UHPLC–MS–MS) was performed on residues collected from the pottery. More...

Featured Product
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.

Improving GPC Reproducibility and Resolution in Polymer Characterization
Tuesday, January 14, 2014, 1:00 PM EST
Increasing challenges in polymer characterization may require methods that provide more detail on the polymers as well as greater accuracy and reproducibility. Selecting the best GPC solution – column, detector and method – can be difficult. This presentation will review column and instrument technologies that provide potential solutions to increase resolution, reduce variability in chromatographic results, and provide enhanced detail in every analysis.
