An article titled "Mira: A Raman Analyzer That Could Become an Innovative Tool" published by Metrohm in the G.I.T. Laboratory Journal has been translated into Japanese, discussing the advantages of portable Raman analyzers and orbital horizontal scanning (ORS). It provides a clear explanation of the principles and usage of Raman analyzers, making it recommended content for beginners who want to try using them. It can be downloaded for free from the link below. (PDF, 2 pages)

This application note presents the construction of a library that clearly distinguishes D-galactose, D-glucose, D-maltose, D-mannose, D-sorbitol, fructose, sucrose, and inositol using a handheld Raman analyzer (Raman spectrometer Mira M-3), and introduces a case where rapid non-destructive identification analysis is possible. It was demonstrated that using Mira allows for clear and rapid identification analysis of sugars without the need for sample pretreatment.

It is possible to confirm that competing commercially available cold medicines are not the same using Raman spectroscopy, and to report the effectiveness of comparing representative sample groups using p-values.

The decision to protect life can be made in the palm of your hand. A portable Raman device is the optimal tool for field officers to quickly test illegal drugs. Officers can safely, swiftly, and accurately handle white powders that may have lethal potential. For example: • During the seizure of street drugs • Investigation of residues from illegal laboratories • Investigation of flammable substances No experts in Raman analysis are needed: the Metrohm Raman Mira DS automatically performs optimal measurements and sophisticated analyses. Consider that the best intelligence is in your palm.

The hazardous materials and illegal drugs investigation team receives a call from the police and heads to investigate the foul odor emanating from an abandoned building on the outskirts of town. Even from outside the window, it is evident that the space is littered with garbage and broken glass bottles, suggesting at a glance that it was a secret laboratory contaminated with chemicals. Nevertheless, the field investigator must conduct an investigation to identify the cause while feeling a sense of danger to their safety. The unique tool the investigator possesses is about the size of a slightly larger mobile phone, featuring a zoom lens reminiscent of a camera, which is being sneaked through the broken window to focus on a white powder on a table one meter away. When the investigator presses the button, a red hazard alert is displayed, warning that the substance is sodium bisulfite. Sodium bisulfite is a chemical used in the process of manufacturing TNT explosives. This unique device is the latest portable Raman analyzer, Mira DS, from Metrohm, and the tool features an innovative stand-off attachment that allows for remote measurement from 1.5 meters away. The combination of this powerful tool ensures the investigator's safe operation and enables a reliable investigation.

Surface-enhanced Raman scattering (SERS) is a phenomenon where the Raman intensity is significantly amplified, often by a factor of 10^7, when molecules are adsorbed onto nanoparticles such as gold or silver. While conventional Raman measurements are limited to detection at the order of 0.1%, SERS allows for the detection of very low concentrations in the ppm or ppb range. Metrom Raman has developed an inexpensive P-SERS kit with high stability and excellent sensitivity by printing nanoparticles onto a substrate using inkjet technology. This kit is particularly effective in the fields of forensic science analysis and food safety. This white paper introduces the mechanism of SERS and examples of the use of Metrom Raman's Mira system.

Raman spectroscopy is an established molecular spectroscopic technique for non-invasive and non-destructive chemical analysis. It is used primarily for the identification of organic materials such as carbon nanomaterials, regulated substances, hazardous chemicals, pharmaceutical raw materials, gemstones and minerals, affected tissues, pigments, and paintings. The portable Raman spectrometer STRam from B&W Tek is portable and equipped with software containing a spectral library, allowing it to provide identification results in under one minute.

The Misa Raman spectrometer with a metronome is a dedicated Raman spectrometer for SERS (Surface-Enhanced Raman Scattering) measurements. It enables the detection and identification of analytes at ultra-low concentrations. MISA was developed as a simple, efficient, and environmentally friendly testing method to ensure food safety. It is characterized by its very high sensitivity, rapid analysis capability, and portability, and comes with flexible sampling accessories, advanced software, and user-friendly consumables included in the package.

The Handheld Raman Spectrometer TacticID can identify unknown substances on-site during tactical activities such as those conducted by emergency responders, security personnel, HazMat teams, and military advance teams. TacticID is rugged and suitable for field use, helping to mitigate risks and manage uncertainty and response times without compromising sample integrity or the chain of evidence.

Electrochemical Raman (EC-Raman) spectroscopy is a powerful analytical tool that enhances the understanding of the functioning of energy storage devices by monitoring physicochemical changes. This application note describes insights gained from EC-Raman during simulation experiments of charging and discharging nickel-hydrogen batteries.

Research institutions need to expand their ability to routinely analyze candidate microplastics from environmental samples. Spectroscopic techniques are suitable for identifying polymers, as they assist in origin identification and help predict biological impacts. Laboratory Raman spectroscopy is a method that enables rapid identification of polymer materials, serving as an alternative to confocal Raman microscopy and Fourier-transform infrared (FTIR) microscopy. However, very small samples are not suitable for conventional Raman analysis. This application note discusses the use of Raman microscopy for the identification of very small microplastic particles.

The portable Raman spectrometer MIRA XTR DS can be mounted on the IBEX CBRNE quadruped robot, allowing the robot to go to sites with explosives and hazardous materials in place of a human, safely detecting and identifying various chemical substances remotely.

The B&W Tek portable Raman spectrometer i-Raman series features a compact and lightweight design with unprecedented capabilities and innovative sampling accessories.
