Mass Spectrometry & Spectroscopy 13 Tailored SWIR lens supports high-accuracy plastics sorting
Manufacturers of plastic sorting and inspection systems are increasingly turning to application-optimised SWIR (Short Wavelength Infrared) lenses to improve the effi ciency and accuracy of recycled plastics recovery.
SWIR spectroscopy enables rapid identifi cation of plastic types such as LDPE, HDPE, polypropylene, PTFE, polystyrene, and PVC - critical for automated sorting in automotive, electronic and household waste streams. However, not all lenses are suited to the high-resolution InGaAs detectors used in these systems.
Rob Watkinson, Sales Manager at Resolve Optics, explained: “Many so-called SWIR lenses are simply visible-range optics with a SWIR-specifi c AR coating. These don’t account for how glass behaves in the SWIR region, leading to compromised image quality - especially when paired with high- resolution sensors. “While off-the-shelf lenses may seem cost-effective, they often result in lower performance, reduced resolution, and bulkier designs. These trade-offs can ultimately limit the effectiveness and appeal of recycled plastics sorting systems. That’s why demand for our instrument-optimised Model 363 SWIR lens has grown signifi cantly in this sector.”
Resolve Optics’ 16 mm focal length Model 363 is specifi cally engineered for SWIR imaging, using selected glass types and coatings to deliver maximum transmission, colour correction, and image clarity across the SWIR spectrum. The lens offers an f/1.6 aperture and less than 2% geometric distortion, producing a sharp 12.8 mm diameter image ideal for modern sorting applications.
With over 20 years of experience in optical design for inspection and sorting systems, Resolve Optics continues to support innovation in the recycling industry with custom and off-the-shelf lens solutions. More information online:

Accelerating polymer and chemical QC with FTIR technology
Anton Paar’s Lyza 7000 FTIR spectrometer is a compact, standalone instrument that delivers fast, reliable ATR FTIR analysis for quality control in polymer and chemical manufacturing.
FTIR spectroscopy with attenuated total refl ectance (ATR) is a well-established method for polymer and chemical identifi cation. Fast, non-destructive, and sample-preparation-free measurement allows reliable identifi cation of polymers, additives, and fi llers within 30 seconds.
FTIR spectroscopy can be used to confi rm material identity, quantify additives, and detect blend deviations. With Lyza 7000, spectral acquisition, comparison, interpretation, and reporting is automated. This reduces QC cycle times to around one minute per sample – enabling fast decision-making on raw materials, blend accuracy, and fi nal product integrity.
Operating the Lyza 7000 FTIR spectrometer is simple and straightforward. With no external PC or complex setup required, lab personnel simply place the sample on the ATR crystal and tap ‘Start’. The device acquires the spectrum in less than 30 seconds, compares it to a validated reference, computes a correlation, and delivers a defi nitive pass/fail report.
Modular cells support a variety of sample types, with module detection enabling rapid cell swaps with no downtime. Internal diagnostics and a status display help ensure stable operation and immediate issue identifi cation, while the touchscreen interface with guided workfl ows enables consistent results with no specialised training.
From raw material verifi cation to fi nal product release, Lyza 7000 delivers fast, reliable results – bringing the capabilities of ATR FTIR into an effi cient, compact system optimised for effective quality control.

High-sensitivity system transforms mass quantitation in complex omics
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.”
