Stockholm University scientists used liquid chromatography coupled with high-resolution mass spectrometry (LC-HRMS) to characterize recycled textile products and detect harmful chemicals.
Identifying "Known Unknowns" in Commercial Products by Mass Spectrometry
May 1st 2014The identification of nontargeted species in environmental and commercial samples by mass spectrometry can be very difficult. In this article, authors from Eastman Chemical Company describe their systematic approach for the identification of nontargeted species using nominal and accurate mass data, searching both mass spectral and "spectra-less" databases.
A Convenient Alternative to MALDI and ESI
May 1st 2014Ionization of small, large, volatile, and nonvolatile compounds with charge states nearly identical to electrospray ionization are produced from a solid matrix or solution with high sensitivity utilizing the vacuum inherent with any mass spectrometer. With the proper matrix, analytes can be analyzed from ambient conditions or by direct introduction into vacuum.
Analysis of Pharmaceuticals and Personal Care Products in River Water Samples by UHPLC–TOF-MS
October 1st 2012A study of pharmaceuticals and personal care products in river water samples is presented from northeastern United States using ultrahigh-pressure liquid chromatography (UHPLC) coupled with TOF-MS for both targeted and nontargeted analytes
Identification of Novel Psychoactive Substances Using Hyphenated Mass Spectrometric Techniques
March 1st 2012Gas chromatography–mass spectrometry (GC–MS) and liquid chromatography–mass spectrometry (LC–MS) techniques offer advantages in separating and confirming the identity of constituents in novel psychoactive substances.
Matrix-Assisted Laser Desorption-Ionization Imaging Mass Spectrometry for Direct Tissue Analysis
A summary of the most recent advances in sample preparation, instrumentation, and data-processing techniques for MALDI-IMS
