24 LDIR Chemical Imaging System for Microplastics Analysis
The enhanced 8700 LDIR Chemical Imaging System from Agilent Technologies has been further optimised for the analysis of microplastics in environmental samples. This newly improved package includes Clarity 1.5 software - a significant upgrade that advances the speed of analysis, enhances spectral acquisition, transformation, and library matching, and provides automated workflows for direct analysis of microplastics on a filter substrate. An innovative, redesigned sample holder allows the on-filter sample to be presented to the instrument more easily and consistently.
Slow and complex analysis solutions are a major challenge to microplastics analysis and have hindered studies of real-world systems. Additionally, method variability limits the comparability of studies, making trends difficult to assess. Vibrational spectroscopy methods such as FTIR and Raman microscopy provide a useful alternative, but each faces limitations due to the excessive time of analysis and method complexity.
The Agilent 8700 LDIR brings high-speed analysis and ease of use to infrared spectroscopy and has rapidly emerged as the benchmark technique for the analysis of microplastics particles. The development of on-filter analysis for this platform marks another leap forward in speed and throughput. The ability to significantly increase testing volumes will allow a greater understanding of the extent of microplastics contamination in the environment and will help facilitate the development of appropriate standards and regulations.
Geoff Winkett, Vice President and General Manager for Agilent’s Molecular Spectroscopy Division, discussed the announcement’s impact. “When I speak with microplastics researchers, a recurring question is how to make testing faster and easier, as there is a real concern that the limited sample numbers that can be realistically processed may be masking the true nature of the issue,” he said. “The fact is that other currently available techniques are too slow and cannot capture the extent of the microplastics load in drinking and environmental waters. Fast and easy-to-use analysis methods such as the 8700 LDIR provide an essential and much-needed alternative that enables researchers to increase sampling over area or time to address these limitations.”

Waters’ Xevo™ TQ Absolute high-performance mass spectrometer is up to 15X more sensitive for quantifying negatively ionising compounds than its predecessor and is 45% smaller and uses up to 50% less electricity and gas supply than other high-performance tandem quadrupole mass spectrometers available on the market. The Xevo TQ Absolute is designed to help pharmaceutical, food and beverage, and environmental analytical laboratories meet regulations requiring trace-level quantitative mass spectrometry analyses for a broad set of applications.
For optimal performance, Waters pairs the Xevo TQ Absolute mass spectrometer with Waters’ ACQUITY™ Premier UPLC System with MaxPeak™ HPS technology which eliminates non-specific adsorption of compounds containing phosphate and/or carboxylate groups and improves their recovery.
Together, this integrated LC-MS/MS system is designed to drive the limits of quantitation to exceptionally low levels for many applications including: quantifying regulated impurities in drug products; performing oligonucleotide bioanalytical assays; measuring concentrations of endogenous metabolites in large cohort clinical studies; quantifying residues and contaminants in food and environmental samples; measuring low-level drugs and toxicants in physiological matrices; detecting trace-level leachables from food packaging.
The Xevo TQ Absolute incorporates thoughtful design features that enable consistent and reproducible analyses, allowing labs to maintain performance and uptime for longer periods in between routine cleaning and service intervals. This is achieved with new guidance on optimal probe positioning for both sensitivity and robustness and a source shield that helps minimise source contamination by the sample matrix or mobile phase salts.
The Xevo TQ Absolute is optimised for use with the waters_connect™ software platform and is also compatible with Waters MassLynx™ mass spectrometry software. For laboratories painstakingly reviewing the results from large numbers of samples, or those quantifying hundreds of small molecule components and contaminants in a single run, the MS Quan app on waters_connect and its unique Exception Focused Review (XFR) functionality, lets scientists review data in up to half the time it used to take them.

Expanded Range of OES Analysis Tools
Alpha Resources LLC, the leading aftermarket supplier of consumables and reference materials, has recently expanded their product line to include supplies for Optical Emission Spectroscopy (OES) analysis. In-stock OES supplies include: electrodes, syringes, o-rings, filters, vacuum pumps, and more.
Alpha’s new OES products are compatible with OES analysis equipment from several leading OEMs, Thermo Fisher Scientific® with all Alpha products, the high-quality lab supplies are compatible for aftermarket use in the specified analysers.
and Bruker® . As
“Many current Alpha customers are in the metalcasting and cement sectors where use of gas combustible analysis machines for quality checks is accompanied by use of an OES analyser. Adding OES aftermarket product lines will allow our customers the convenience of ordering lab supplies from a trusted vendor,” noted Ken Mantei, Director of Operations, at Alpha Resources. “Customers know that Alpha’s quality is second to none and that they will pay less from an aftermarket supplier like Alpha than they would to an OEM.”
