Pneumonia microorganisms: Accelerated identification in clinical setting

Date: Dec 16, 2015

Author: Steve Down

Using MALDI TOFMS to identify the microorganisms in ventilated patients with pneumonia reduced the time before refinement of the antibiotic therapy and also the time spent in the intensive care unit.

Journal Highlight: Electron ionization LC-MS with supersonic molecular beams — the new concept, benefits and applications

Date: Dec 7, 2015

Author: spectroscopyNOW

A new type of electron ionization LC-MS with supersonic molecular beams is based on pneumatic spray formation of the LC liquid flow in a heated spray vaporization chamber, full sample thermal vaporization and subsequent electron ionization of vibrationally cold molecules in supersonic molecular beams.
