Rigaku Raman Technologies offers the world's first dual wavelength Raman analyzer; the Xantus-2. The instrument has been developed to meet customers’ specific application needs for quality data analysis. Featuring options of 532 and 1064nm or 785 and 1064nm lasers stabilized for Raman spectroscopy, the Xantus-2 provides an exclusive combination of minimized fluorescence and high sensitivity. The Raman analyzer is portable and meets the needs of today's classrooms and laboratories.
Integrated Software
Xantus-2 uses integrated software that merges open architecture with customizable, user-defined settings for improved sampling parameters. This promotes detailed and actionable data analysis. The analyzer can perform analysis directly through sample containers without changing or destroying the sample. It is fitted with sampling accessories for liquids, solids, and powders. Users can conduct fast quantitative and qualitative analysis and can directly monitor oxidation and reduction reactions via clear/ amber-colored glass vessels.

Xantus-2: Lightweight and Portable
Xantus-2 is lightweight, portable and battery operated. It supports an integrated academic lab-lecture approach to education enabling hands-on lab analysis in the classroom. In addition, the instrument empowers scientists to carry it across multiple laboratories and classrooms for a more collaborative environment.
Customized Solutions
Rigaku Raman Technologies offers sophisticated analytical instruments that are customized to meet specific applications needs of the user. With a choice of laser configuration suitable for material analysis, users can optimize sampling sensitivity. Laser configuration includes:
- 532nm for semi-quantitative applications, where analytical sensitivity is essential and fluorescence is not an issue
- 785nm for non-fluorescent samples that need high sensitivity
- 1064nm for highly fluorescent samples usually found in the biopharmaceutical and pharmaceutical industries
Xantus-2 with Dual Wavelength Advantage
Xantus-2 combines two different detector array options and excitation wavelengths in a single device. It reduces intrinsic fluorescence issues and provides a wide range of materials analysis capabilities.

Figure 2. This image shows the spectra collected from a single sample at both 1064nm and 785nm excitation. With the 785nm excitation a large fluorescence band is seen which obscures all but the strongest Raman bands in the sample. However, when the 1064nm excitation was used, very clear Raman bands are seen, allowing for definitive identification of the sample.
Following are the key features of Xantus-2:
- Cooled detectors -CCD and InGas
- Patented volume phase transmission grating with 95% spectral efficiency
- Variable focal point adjustment
- High Power - 490mW power variable in 1mW increments
- Integrated vial holder
- 21 CFR Part 11 compliant software
