Advances in Non-Targeted and Suspect Screening to Identify Unknowns Using Mass Spectrometry
March 18th 2019This morning session, chaired by Ann Knolhoff of the Food and Drug Administration, starts at 8:30 am and will cover different approaches for developing and implementing non-targeted and suspect screening workflows using high-resolution mass spectrometry to identify unknowns.
The LCGC Blog: Have We Forgotten the Advantages of Core–Shell Particles?
March 12th 2019In the late “noughties” we couldn’t avoid the webinars, seminars and online calculators which were being released by HPLC column manufacturers to extol the virtues of the “new” core-shell particle morphology that promised high performance at lower back pressures.
Recent Advances in Solid-Phase Microextraction, Part 1: New Tricks for an Old Dog
March 1st 2019Solid-phase microextraction (SPME) was introduced nearly 30 years ago and since that time has matured into a widely used tool in the arsenal of sample preparation techniques. Simultaneously, it has spawned a host of related techniques where sorbent coatings are placed on stir bars, magnetic particles, vial walls, and so on. Over the past few years, several advances in SPME have been developed, including increasing the sorbent surface area available for extraction, accommodating direct analysis by mass spectrometry (MS), and sorbent overcoating to resist fouling by sugars, lipids, and other macromolecules present in some sample types. These advances are discussed in this month’s instalment. The use of SPME for microsampling of biological systems, so-called bio-SPME, will be the focus of Part 2.
Perspectives on the Adoption and Utility of 1.0-mm Internal Diameter Liquid Chromatography Columns
March 1st 2019One millimetre internal diameter liquid chromatography columns are available from many manufacturers. In this article, the utility of 1.0-mm internal diameter (i.d.) columns, and the arenas in which they play a relatively strong role, are investigated. Further, the advantages and disadvantages of 1.0 mm diameter columns are contrasted with both larger- and smaller-bore formats.
