7. Video: Waters REIMS™ Research System with iKnife™ Technology Advances Food Fraud Testing
The Rapid Evaporative Ionization Mass Spectrometry™ (REIMS™) Research System with iKnife™ Sampling combines direct-from-sample ionization with high performance time-of-flight mass spectrometry and powerful, intuitive analytics. The system eliminates the need for sample preparation and chromatographic separation, providing food, microbiology and tissue researchers with near-instantaneous data acquisition. Watch now
8. Product news: Phenomenex Enhances Kinetex Core-Shell Family with pH 1-12 Stable 2.6µm and 1.7µm EVO C18 Columns
The Kinetex EVO C18 columns provide a unique C18 selectivity, offering excellent peak shape for bases, 100% aqueous stability and rugged pH stability from 1 to 12 by incorporating a patented organo-silica grafting process that utilizes uniform stabilizing ethane cross-linking. The new, smaller particle sizes extend the versatility and scalability of this media, introduced initially in 5µm particles for HPLC and preparative HPLC work. Read more
9. Application note: Enhanced Separation and Identification of Fungicides in Wine by Headspace SPME–GC×GC–TOF MS
This application note describes how the enhanced separation offered by GC×GC can be coupled with the exceptionally sensitive BenchTOF-HD mass spectrometer to enable the screening of wine for trace-level fungicides, as well as compounds giving rise to organoleptic faults. Trace levels of fungicides are difficult to detect using conventional quadrupole GC–MS, without resorting to selected ion monitoring mode. Download here
10. Application note: Screening and Verifying Mycotoxins in Food with Q-TOF LCMS and an Accurate Mass Library
This application note describes the creation of an accurate mass library for mycotoxins and related metabolites and its application for the screening of mycotoxins in food. An Agilent 1290 Infinity LC coupled to an Agilent 6550 iFunnel Q-TOF LC/MS was operated in positive and negative electrospray with dual-spray Agilent Jet Stream Technology. Accurate mass spectra were acquired for a large collection of mycotoxins and related metabolites in one or both ionization modes and for all relevant ion species. Download here

FastPrep-24™ 5G
MP BiomedicalsThe FastPrep-24™ 5G Instrument is quite simply the most advanced sample preparation system ever! The only high-speed benchtop homogenizer featuring microprocessor-controlled, Hi-Def Touch Screen Programming makes the 5G the ultimate in ease, speed and performance for sample preparation applications where it is necessary to grind, lyse, or homogenize difficult and routine samples, allowing easy and reproducible isolation of stable RNA, active proteins and full-length genomic DNA. Applications include but are not limited to: biological tissues, fluids and excretions cell cultures environmental sample other inorganic solid matrices. The FastPrep-24™ 5G Instrument uses a unique, optimized motion to disrupt cells through the multidirectional, simultaneous beating of specialized Lysing Matrix beads on the sample material. Samples and buffers are added to Lysing Matrix Tubes containing specialized Lysing Matrix beads, supplied ready-to-use, certified nuclease-free and in a variety of sample type specific compositions. The sample tubes remain securely sealed during the processing and the single use design eliminates cross-contamination. Program parameters are easily set using the touch screen user interface, or choose from many Recommended Programs stored on the 5G's onboard computer. With a simple touch of the "run" button, in less than a minute your samples are completely lysed, super fast, every time! The highest power settings available ensure that DNA, RNA and proteins, even from difficult samples, are quickly liberated into the protective buffer, thus preserving their biological function.
