In this equipment roundup, the editors of LCGC International highlight new instruments from Bruker and Shimadzu.
In this equipment roundup, the editors of LCGC International highlight the newest products from instrument manufacturers around the world.
In late May, Shimadzu Scientific Instruments announced the release of the LCMS RX series of triple quadrupole mass spectrometry instruments (1), which are supported by integrated hardware and software technologies to ensure reliable and robust results at lower operating costs.
The company also introduced a suite of new technologies with the RX series including the CoreSpray, which enhances reliability by increasing gas flow and improving nebulizer coaxiality. This improves the heat distribution of the ionization source, ensuring unparalleled sample ionization, significantly enhancing the reliability of analytical data. The IonFocus electrode, once exclusive to the LCMS-8060NX, is now a standard feature across all RX models. It removes matrix contaminants, resulting in lower noise levels, improved data quality and reduced maintenance needs.
Shimadzu’s LCMS includes enhanced software capabilities to autonomously monitor the system, reducing the need for manual intervention. Furthermore, the performance concierge proactively evaluates system performance with a standard solution, troubleshoots problems and notifies operators of maintenance needs, effectively minimizing instrument downtime.
The LCMS RX series also includes an ecology mode function that automatically checks system status and shuts the instrument down after sample queues are completed. This reduction in power consumption minimizes the running cost of the laboratory and consumes less resources.
The RX series consists of the following models:
At the American Society for Mass Spectrometry (ASMS) conference in Anaheim, California, Bruker Corporation announced the launch of a novel, high-performance matrix-assisted laser desorption–ionization-tandem time-of-flight (MALDI-TOF/TOF) system, the neofleX Imaging Profiler for mass spectrometry-based tissue imaging (2). It enables facile OME-TIFF file output via the new SCiLS Scope software. The neofleXMALDI-TOF/TOF imaging mass spectrometry (MSI) system now conveniently fits on a benchtop.
This instrument comes standard with Bruker’s proprietary 10 kHz smartbeam3D laser for true pixel fidelity and with enhanced imaging detectors designed for longitudinal robustness, stability, and reproducibility in linear and reflector modes. neofleX is also available as a TOF/TOF configuration that features a reimagined fragmentation module for significantly improved TOF/TOF sensitivity, speed, and sequence coverage.
In addition to MALDI HiPLEX-IHC MSI immunohistochemistry, neofleX is also compatible with the MALDI-ISH (in situ hybridization) method announced at ASMS 2024 by AmberGen, Inc. MALDI-ISH multiplexes imaging of up to 12 oligomers of interest for multiomic spatial tissue research in neuroscience, infectious disease, and oncology.
According to the manufacturer, the neofleX excels at providing more insight per pixel through multiomic spatial biology data from tissue sections that can positively correlate targeted proteins with glycans, metabolites, lipids, endogenous peptides, xenobiotics, and now RNA/DNA. This additional multiomics context provides important adjacency information about cellular states, function, structure, and protein activity for a range of research areas, such as oncology and neurology.

Characterization and Assessment of Effects of Drying Temperature on Edible Mushrooms with HS-GC–MS
September 6th 2024To gain insight into the effect of drying temperature on its composition, headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC–MS) was used for the identification of volatile organic compounds (VOCs) of 86 mushroom samples that were divided into five groups and dried at different temperatures.
Modern HPLC Strategies: Improving Retention and Peak Shape for Basic Analytes
August 16th 2024In high-performance liquid chromatography (HPLC), it is common for bases and unreacted ionized silanols on silica-based columns to cause irreproducible retention, broad peaks, and peak tailing when working with basic analytes. David S. Bell, Lead Consultant at ASKkPrime LLC offers innovative HPLC strategies that can help mitigate such issues.
Real-Time Measurement of EPA Regulated HON Compounds and Environmental Pollutants Using SIFT-MS
September 6th 2024This application note describes the determination of method detection limits (MDLs) for the newly regulated HON (Hazardous Organic NESHAP) compounds, which validate SIFT-MS as an effective solution for measuring these toxic VOCs and other environmental pollutants in ambient air, whether at the fence line or in a mobile setting.
