AMS Transitions From Research to Practice

February 19, 2015 2:00 pm | by Tim Studt, Editor-in-Chief, R&D Magazine | Articles | Comments

Accelerator mass spectrometry (AMS) is an analytical technique for measuring isotope ratios with high selectivity, sensitivity and precision. Initially developed more than 75 years ago by Robert Cornog and Luis Alvarez at the Univ. of California, Berkeley, there are now more than 110 AMS systems in 28 countries around the world, mostly at government and university labs, but a few at private companies as well.

Using TLC to Choose an HPLC Column

December 10, 2014 11:55 am | by Fred Rabel, Owner, ChromHELP, LLC, Woodbury, N.J. | Articles | Comments

Because of the high cost of HPLC columns, there are numerous ways to find out which column(s) might best be of use for an intended but new separation. If some of the components are known, then the literature or manufacturers’ websites can be consulted. This might take some time, but the research of others can save both time and money in your own work.

pH Gradient Speeds Separation of Antibodies

December 10, 2014 11:47 am | by Ken Cook, Frank Steiner, Mauro De Pra, Thermo Fisher Scientific, Inc. | Articles | Comments

Soft Ionization Drives Future GCMS Technology

December 10, 2014 11:37 am | by Laura McGregor, Nick Bukowski and David Barden, Markes International, UK | Articles | Comments

Soft ionization remains a relatively underused technique for GCMS, despite its ability to provide improved confidence in the identification of a range of challenging analytes. But there is now a new approach that makes it possible to lower the energy of electron ionization to achieve soft ionization, without the disadvantages with which it has historically been associated.

Higher Performance, Smaller Sizes Define Future Mass Spec

December 10, 2014 11:23 am | by Sarah Smith, Global Market Manager, Analytical, Bal Seal Engineering Inc., Foothill Ranch, Calif. | Articles | Comments
