Environmental Methods High Performance GC-TOFMS E-Seminar
On Thursday, March 16, LECO Corporation will host a complimentary e-seminar for the mass spectrometry community at 12:00 pm EST. This e-seminar will be presented by LECO applications chemist Jonathan Byer, PhD, and is titled, “”Exceed the Requirements of Standard Environmental Methods: Perform Target and Non-Target Analysis in a Single Run Using a High Performance GC-TOFMS”.
The e-seminar will evaluate the advantages of full scan data at near SIM detection limits for standard environmental methods and will demonstrate how high performance GC-TOFMS can be used to exceed the specifications of these method requirements. Unique attributes such as spectral deconvolution, target and non-target analysis in a single sample injection, and better-than-nominal mass accuracy will be highlighted. In particular, limits of detection were determined for semi-volatile organic compounds by EPA Method 8270, in drinking water by EPA Method 525.5, and in food commodities for pesticide residue analysis.

Raw Cat Food Could Spread Antibiotic-Resistant BacteriaNews
Scientists have found that raw cat food was associated with contamination of cats' feces with Enterobacteria that contained the enzyme beta-lactamase. This particular enzyme is important because it can break down a chemical structure called the lactam ring. This is important because it forms a part of numerous antibiotics - no lactam ring, no antibiotic activity.READ MORE
Physicists Develop Faster Way to Make Bose-Einstein CondensatesNews
Physicists have invented a new technique to cool atoms into condensates, which is faster than the conventional method and conserves a large fraction of the original atoms. The team used a new process of laser cooling to cool a cloud of rubidium atoms all the way from room temperature to 1 microkelvin, or less than one-millionth of a degree above absolute zero.READ MORE
