The LCGC Blog: Useful Tips for GC-MS
March 19th 2015There are many aspects of analytical science which abound with myth and legend – but gas chromatography – mass spectrometry (GC-MS), and more specifically the electron ionization (EI) process, stands out as the technique which has given rise to the largest number of ‘urban myths’ and misunderstandings.
Applications of Ultra-high Resolution Mass Spectrometry for Metabolomics
March 19th 2015Ultra high resolution, accurate mass (UHRAM) mass spectrometry is a powerful new approach to high throughput screening and quantitation in complex sample matrices. To learn more about how UHRAM is used in metabolomics, LCGC talked with Jason Locasale, Assistant Professor in the Division of Nutritional Sciences at Cornell University.View the associated whitepaper.
Determining Child Phthalate Exposure
