Using visible-near infrared (Vis-NIR) spectroscopy, we determined several chemical and physical parameters in lubricating oil, including acid value (AN), kinematic viscosity at 40°C, moisture content, and color. This application note presents an example of how these parameters were measured quickly and simultaneously using Metrohm's near-infrared analyzer (Vis-NIRS).

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.

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.
