Parker Balston introduces the SOURCE LCMS-5000 LC–MS gas generation system, which produces nitrogen, zero air, and exhaust pump gases. It combines a compressor with coalescing filters, catalysts, and hollow-fiber membranes to produce these gases. Parker Hannifin Corporation, Haverhill, MA; www.parker.com
Two ICP-MS instruments from Varian are designed for elemental analysis of complex samples. The model 810-MS and 820-MS instruments contain high-efficiency 90-degree ion optics and a double off axis quadrupole designed to provide low background noise and gigahertz sensitivity. The model 820-MS also includes the company's collision reaction interface, which reportedly enables the use of collision and reaction gases such as helium, allowing lower detection limits and more accurate quantitation for difficult elements in complex samples.

BURLE Electro-Optics' 5905 MAGNUM detector is designed to provide high dynamic range, increased gain stability, and near elimination of feedback noise. A proprietary glass formulation reportedly facilitates long detector life. The detector is designed specifically for Thermo Finnigan mass spectrometers; the electron multiplier cartridge is a plug-in replacement that fits directly in to the Thermo Finnigan mounting assembly. Its one piece construction eliminates fastener and connection problems. BURLE Electro-Optics, Sturbridge, MA; www.burle.com
High-Speed Laser MS for Precise, Prep-Free Environmental Particle Tracking
April 21st 2025Scientists at Oak Ridge National Laboratory have demonstrated that a fast, laser-based mass spectrometry method—LA-ICP-TOF-MS—can accurately detect and identify airborne environmental particles, including toxic metal particles like ruthenium, without the need for complex sample preparation. The work offers a breakthrough in rapid, high-resolution analysis of environmental pollutants.
