Breaking the Mass Spec Logjam

August 28, 2013 8:07 am | Award Winners

Mass spectrometers offer an accurate way to profile the metabolites of biological reactions, but current technologies rely on time-consuming chromatography techniques for sample preparation, and are costly for large-scale screens. Lawrence Berkeley National Laboratory scientists have removed this barrier with HT-NIMS Screening technology, which simplifies sample preparation and boosts machine throughput a hundred-fold.

New Configuration for ICP-MS

August 28, 2013 8:06 am | Agilent Technologies Inc. | Award Winners

When inductively coupled plasma mass spectrometry (ICP-MS) was first developed, it was expected to provide highly sensitive, interference-free spectroscopic element analysis. However, chemists quickly noticed that ICP-MS suffers from numerous interferences resulting from matrix and plasma ions of matching masses. To address these sufferings, Agilent Technologies International Japan Ltd. developed the Agilent 8800 Triple Quadrupole ICP-MS (ICP-QQQ), which is the first ICP-MS with a tandem mass spectrometer, or MS/MS, configuration.

Innovation in Biomolecular Quantitation
