Mass Spectrometry & Spectroscopy 19 Pyroelectric receiver delivers quick and easy IR detection
Laser Components has launched the second-generation model in its Pyroelectric Receiver series – the PR No2 – offering a plug-and-play solution for fast, accurate measurements in lab environments.
Designed for use in applications such as FTIR, TDLAS, infrared fi bre lasers, and supercontinuum sources, the PR No2 connects easily via standard power and signal outputs, streamlining setup and data acquisition.
This latest receiver combines a high-performance detector with upgraded electronics, allowing it to handle higher light intensities. As a result, users can obtain reliable readings across a broad spectral range, from ultraviolet (UV) through to terahertz (THz) frequencies.
Two models are available: the PR No2 IR, optimised for long-wave infrared with a KBr window, and the PR No2 THz, equipped with an HDPE window for THz measurements. The IR model features an extended 3 dB electronic bandwidth of at least 35 kHz (typically 50 kHz), while the THz version delivers a 3 dB bandwidth of 50 kHz.

High-sensitivity system transforms mass quantitation in complex omics
Advanced fully-fused tablet dissolution fl ow cells
Monolithic all-quartz construction unlocks capabilities impossible with jacketed cells: full immersion cleaning and wide range temperature applications across the entire dissolution fl ow cell portfolio. Where the market offers only selective availability, Starna Scientifi c delivers comprehensive coverage.
All-quartz construction enables full cell immersion in acids and solvents for enhanced cleaning whilst supporting extreme temperature applications beyond jacketed cell limitations. This dual capability expands both cleaning protocols and testing conditions previously unavailable, including autoclavable sterilisation.
Delivering these expanded capabilities across every dissolution geometry draws on six decades of quartz manufacturing expertise and advanced heat-fusion technology, whilst continuing our established jacketed cell production.
Direct heat-fusion creates single-piece, solid quartz bodies without metal components. This design ensures leak-proof performance whilst delivering optical clarity, chemical inertness, and temperature tolerance. Precision-cut internal quartz threads enable secure tubing connections.
Where others provide limited variants, every application now has an all-quartz solution. Precision quartz threading delivers consistent performance across all geometries, eliminating protocol variations.
SCIEX has launched the ZenoTOF 8600 system at ASMS 2025, offering a signifi cant advance in accurate mass quantitation for researchers working across proteomics, metabolomics, and lipidomics. Combining high sensitivity with expanded software capabilities, the new platform enables scientists to confi dently quantify thousands of molecular species from complex biological samples in short acquisition times.
The ZenoTOF 8600 builds on SCIEX’s decades of innovation in mass spectrometry, incorporating new hardware to boost ion generation and transmission. The OptiFlow Pro source, along with DJet and QJet ion guides, improves ion throughput and, when used with the Zeno trap, delivers up to tenfold greater sensitivity compared to the ZenoTOF 7600+. A new optical detector supports higher ion currents, while Mass Guard technology - originally introduced on the SCIEX 7500+ - reduces contamination and improves instrument uptime.
The system also debuts ZT Scan DIA 2.0, an upgraded data acquisition method that expands mass range coverage and enhances performance across all omics disciplines. According to Dr Nicola Zamboni, Principal Investigator at ETH Zurich, “We’re not just detecting more compounds - we’re identifying up to 40% more. ZT Scan DIA 2.0 gives us access to new layers of biological insight, particularly for lipids and complex natural products.”
To support the high data throughput of the ZenoTOF 8600, SCIEX OS 4.0 introduces faster, more automated workfl ows for effi cient processing. The updated software ecosystem also supports third-party integration. New collaborations include MS-Dial, which now supports SCIEX raw data in multiple scan modes, enhancing small molecule identifi cation via spectral deconvolution. In proteomics, SCIEX continues its partnership with Bioinformatics Solutions Inc, whose PEAKS Studio 13 provides expanded peptide and PTM identifi cation, optimised for ZT Scan DIA, SWATH DIA, and DDA data.
“The ZenoTOF 8600 and its supporting tools are already making a real difference in omics research,” said Dr. Jose Castro-Perez, Vice President of Product Management at SCIEX. “We’re excited by the depth of insight our customers are starting to uncover.”

Monitoring disinfection byproducts in drinking water: A sensitive IC-MS/MS approach
While chlorination is essential for controlling pathogens in drinking water, it can produce harmful byproducts, including haloacetic acids (HAAs), dalapon, and bromate, some of which are potentially carcinogenic. Regulatory bodies like the US EPA and the EU have set a maximum contamination limit of 60 µg/L for the sum of five key HAAs (HAA5: MCAA, MBAA, DCAA, DBAA, TCAA).
EPA Method 557 outlines a procedure for quantifying these compounds at trace levels across diverse water types. In this method, a Metrohm ion chromatograph (IC) is paired with an Agilent triple quadrupole mass spectrometer (MS), enabling direct, high-sensitivity analysis without the need for sample extraction. The Metrohm Suppressor Module minimises eluent interference, while the Metrosep A Supp 19 column ensures excellent separation of analytes from matrix components.
Even in complex water samples, matrix spike recoveries at 1 µg/L ranged from 65–115%, and minimum reporting levels (MRLs) fell between 0.025 and 0.25 µg/
L.This robust IC-MS/MS method fully complies with EPA Method 557 and provides a reliable tool for safeguarding drinking water quality.
