Applications

Metrohm has shaped moisture analysis for more than half a century. Find out about new developments in water analysis and learn how near-infrared spectroscopy in combination with Karl Fischer titration can increase your sample throughput and boost your productivity.

This white paper differentiates between methods for identification of unknowns and verification of known materials. The goal of this publication is, ultimately, to inform the user of the capabilities of the handheld Metrohm Raman Mira P system. Best practices for building robust training sets for materials verification with Mira P can also be found here.

Surface Enhanced Raman Scattering or SERS is an anomalous enhancement of Raman scattering when molecules are adsorbed to gold or silver nanoparticles – this enhancement can be as large as 107. The advantage of SERS for the analytical chemist lies in its ability to detect analyte concentrations of parts per million and even parts per billion levels, while classical Raman is limited to parts per thousand. Metrohm Raman produces P-SERS assays in the form of nanoparticles printed onto substrates using inkjet technology. This method produces inexpensive test strips that exhibit exceptional stability and sensitivity. There are two markets that can be easily addressed with P-SERS: forensic analysisand food safety. This white paper explains the mechanism of SERS and how it can be applied to handheld Raman analysis with Metrohm Raman Mira systems.

An analytic chemist in your back pocket. A forensic laboratory in a suitcase. A HazMat team in the trunk of your car. First responders need all the help they can get when faced with potentially dangerous substances. Mira DS from Metrohm Raman is a sophisticated chemical analyzer that replaces the specialist with automation. The push of a button initiates proprietary Smart Acquire routines to optimize acquisition parameters and collect the highest quality spectra. These spectra are automatically subjected to library search and Mixture Matching routines capable of identifying up to three components of a mixture. When hazardous substances are detected, the user is alerted to immediate action with color-coded warnings.

Metrohm Raman presents a unique handheld materials identification system designed to meet the needs of defense and security professionals. Meet Mira DS, the most adaptable Raman analyzer available today. Mira DS was developed directly in response to requests from first responders in the field for a small, rugged, automated materialsidentification system that ensures the safety of the user in any situation.

Near-Infrared spectroscopy (NIRS) is a widely used analytical technique for quantitative analysis of various products in research and industrial applications. This white paper summarizes the workflow of the development of quantitative methods according to ASTM E1655.

Near-infrared spectroscopy (NIRS) is a widely used analytical technique for qualitative and quantitative analysis of various products in research and industrial applications. Because of different reasons it might be necessary to transfer analytical methods from one NIR analyzer to another one. This white paper summarizes the workflow of such method transfer.

Chemometrics is a powerful tool widely used for method development in the pharmaceutical industry. This whitepaper describes the lifecycle of multivariate models and summarizes the workflow of the development of chemometrical models according to the new USP chapter <1039>.

Detection of threatening materials requires robust and sophisticated instruments capable of safe, instantaneous field-analysis of unknowns. In an environment where there is an ever-evolving threat of explosives made from commonlyavailable chemicals, explosive libraries must be customized constantly to include newly targeted materials. Mira DS from Metrohm Raman is the perfect solution for detection of explosives in the field. This handheld Raman instrument is equipped with sophisticated analysis algorithms and a suite of safety features for first responders who need the identity of a potential hazard... NOW! Mira DS and its software can be customized to respond to emerging hazards: this note describes procedures for creating custom libraries of binary explosive precursors to be used in library comparison and mixture matching routines on Mira DS. With these tools, unknown substances can be identified with color-coded warnings for fast action in critical situations.

A person suspected of possessing a narcotic can be charged with a crime only after the identity of the illicit substanceis confirmed. This confirmation is typically provided by analytical chemists in forensic laboratories and requires highly technical separation and detection methods. Unfortunately, such labs often have deep caseloads that lead to delays in testing. Handheld Raman analyzers bring the reliability and accuracy of lab analysis to first responders in the field, allowing for rapid and accurate identification of street drugs with a white powder appearance. With such tools, demand for forensic analysis can be reduced and enforcement agencies can enforce drug policies with greater safety, speed, and precision.
