  • Ion Mobility Mass Spectrometry – Catch the Excitement!

    Interest in ion mobility mass spectrometry (IMS) technology is growing rapidly. The signs are everywhere. Since the year 2000, the number of abstracts submitted to ASMS mentioning ion mobility has grown more than 10-fold – from 30 to more than 350 in 2015. For most of that time, ion mobility has been available commercially in high-end research instruments or in homemade platforms. Waters ...

  • Feasibility of Soil Dust Source Apportionment by the Pyrolysis-Gas Chromatography/Mass Spectrometry Method

    This study tested the feasibility of using pyrolysis (Py)-gas chromatography (GC)/mass spectrometry (MS) to obtain organic chemical species data suitable for source apportionment modeling of soil-derived coarse particulate matter (PM10) dust on ambient filters. A laboratory resuspension apparatus was used with known soils to generate simulated receptor filter samples loaded with #1;0.4 mg of PM10 ...

  • Detailed characterisation of essential oils by flow-modulated GC×GC and Tandem Ionisation mass spectrometry

    Volatile oils of plants, also known as essential oils, have been used for many years for their flavour, fragrance and medicinal properties. However, their extreme complexity and diversity presents analysts with a significant challenge when it comes to quality control. They are generally composed of monoterpenes and sesquiterpenes, as well as their oxygenated derivatives, such as aliphatic ...

  • Changing the Rules with Mass Detection

    How simplified detectors can provide mass data for every analytical run and speed up method development With access to multiple mass spectrometry systems of varying degrees of sophistication, Davy Guillarme (University of Geneva, Switzerland) wasn’t actively looking for new mass detection solutions. Nevertheless, the Waters ACQUITY QDa mass detector caught his eye. Why? Because it opens a ...

  • Ultra-Pure Proof with Mass Detection

    Before joining the newly formed Reach Separations in February 2012, I spent five years at AstraZeneca in analysis and purification (latterly as group lead in reversed phase and chiral purification). This experience gives me a good perspective of both the needs of “big pharma” and, more recently, the needs of a specialist separation solution provider. My ...

  • Resolution in life and mass spectrometers? It really depends…

    “How few there are who have courage enough to own their faults, or resolution enough to mend them.” Benjamin Franklin As I sat one morning before work staring into my green tea leaves at the bottom of my cup and reflecting on my resolutions achieved and resolutions that evaded me in 2015, I resolved to make 2016 a better year. The ‘missed’ resolutions ...

  • Simon Fraser University Opens Suite of Mass Spectrometers for Natural Products Discovery Research

    As a graduate student at the University of British Columbia, Dr. Roger Linington discovered his future life’s work serendipitously. While studying sponges, it became clear to him that one of the challenges in studying macroorganisms is their limited or slowly replenishing supply. To perform mechanism and mode-of-action studies, he needed a larger, more accessible source of ...

  • Target GC-MS Analysis using Accelerated Column Heating and Interactive Deconvolution Software

    In diverse fields ranging from environmental samples to complex fl avor preparations, high performance, high resolution capillary gas chromatography/mass spectrometry, GC-MS, has become the preferred technique for identifying and quantifying target compounds at trace levels. Many of these samples are characterized by very complex matrices, which provide a substantial challenge for contemporary ...


  • In Beverly, the Shoe Fits for Bioanalysis!

    This past May, many of the nation’s leading bioanalysts gathered in New England to share ideas and explore the latest advances in mass spectrometry, liquid chromatography, and sample preparation for large molecule quantification. At Waters’ semi-annual bioanalysis workshop, scientists from across the U.S. trained on the latest mass spectrometry instrumentation at our demonstration ...

  • Degradation of carbendazim by UV/H 2O 2 investigated by kinetic modelling

    Abstract The transformation of the fungicide carbendazim (methyl-2 benzimidazole carbamate) induced by hydroxyl radical generated by the UV photolysis of H 2O 2 has been studied in dilute aqueous solution. The efficient reaction of hydroxyl radicals with carbendazim led to the rapid degradation of carbendazim. The study of reaction kinetics yielded a second order rate constant of 2.2±0.3 10 9 M ...

  • Innovations in Site Characterization. Case Study: Hanscom Air Force Base, Operable Unit 1 (Sites 1, 2, and 3)

     Executive Summary Field analytical instrumentation and methods were used to support a site characterization study at the Airfield at Hanscom Air Force Base (HAFB) Operable Unit 1. HAFB is located in Middlesex County, Massachusetts, and occupies land in the towns of Bedford, Concord, Lexington, and Lincoln. U.S. Air Force military operations began in 1941 and continued through 1973. With ...

  • Enhanced separation of hop oils by flow-modulated GC×GC–TOF MS with Tandem Ionisation

    Beer contains hundreds of organic ingredients, with concentrations spanning many orders of magnitude, and including monoterpenes (C10) and sesquiterpenes (C15). These are aroma-active hydrocarbons found in the essential oils of various plants, including hops, and provide much of the characteristic ‘bitterness’ of the finished beer. Of the greatest importance for beer is the ...
