igaku Raman Technologies has added two compact and easy-to-
use fibre optic probe accessories for its Xantus-2 785nm and 532nm portable Raman analysers.
Designed for pharmaceutical, research, analytical and industrial applications, the new Raman Probe II and Economy Probe will enable customers to significantly improve routine laboratory Raman spectroscopy and support true in situ analysis of an even broader range of materials.

“As our customers look to improve analysis capabilities and explore new applications with Raman spectroscopy, we will continue to enhance our products to provide valuable solutions to fit their needs,” said Bree Allen, general manager at Rigaku Raman. “Te addition of these two lightweight and easy- to-use probe accessories enables customers to broaden their use of lab-based Raman spectroscopy
and truly improve workflow efficiency.”
Using the new probes, Xantus-2 customers will be able to perform analysis on a variety of materials, including dark or turbid solutions, and fulfil applications such as immersion analysis that standard spectroscopic platforms cannot achieve. In addition, both probe options are lightweight and small enough to fit inside typical laboratory-scale vessels, enabling customers to transport them to any location and share among multiple departments.
Rigaku says Xantus-2 is the world’s first dual wavelength Raman analyser designed to provide customers with application-specific solutions for quality data analysis. It is equipped with options of 785 and 1064nm or 532 and 1064nm lasers stabilised for Raman spectroscopy, providing a novel combination of high sensitivity and minimised fluorescence.
Te analyser uses integrated software combining open architecture with customisable, user-defined settings for optimised sampling parameters that result in comprehensive and actionable data analysis. Equipped with sampling accessories for solids, liquids and powders, the Xantus-2 can perform analysis directly through sample containers without altering or destroying the sample. Users are able to perform rapid quantitative and qualitative analysis and monitor reactions such as oxidation and reduction directly through clear/amber- coloured glass vessels.
Te company has also announced software enhancements to Xantus-2 that are designed to improve customer efficiency and ensure high levels of standards compliance. Te new Xantus-2 version 3.0.0.0 software includes a redesigned account management user interface for stronger instrument security and data protection for enhanced compliance with 21 CFR Part 11 guidelines. Simplified data management and storage functions enable easier management of multiple libraries, while automatic naming convention and file saving features eliminate inconsistent storage locations and file names by multiple users.
New from Shimadzu is the IRTracer-100 Fourier Transform Infrared (FTIR) spectrophotometer that combines high speed, sensitivity, and resolution with enhanced expandability and easy-to-use software. It obtains high-quality data for samples in fields such as pharmaceuticals, foods, chemicals and electronics.
