Applications

Enhancement of SERS features by electrochemical activation in non-aqueous media.

A good portable Raman spectrometer bridges the gap in performance, capability and size between handheld and benchtop Raman spectroscopy.

Two chemical analyses from one tablet using Raman to identify the major component and SERS for the minor component.

Commercial SERS substrates are readily available, making SERS an accessible technique for low-concentration detection. In this application note, residual phosmet insecticide on apple skin is detected using SERS.

Surface-enhanced resonance Raman scattering is a technique that offers unparalleled sensitivity and specificity in non-destructive spectroscopic detection. It is a combination of surface-enhanced Raman scattering and resonance Raman spectroscopy.

The work shown in this paper suggests that Raman based spectrometers enabled by the High-Throughput Virtual Slit can be useful for in situ real time verification of the inclusion complex formation.

This application note describes detection of trace amounts of potassium ferrocyanate in table salt.

This application note describes the use of the Metrohm Instant SERS Analyzer to provide quick, easy and robust detection of melamine in a complex food matrix.

This application note compares intelligent spectra eXTRaction Raman technology with conventional 785 nm and 1064 nm Raman devices for the analysis of chemicals that are difficult to measure due to their known fluorescent properties.

A hybrid system using holography and Raman spectroscopy offers promise for monitoring microplastics at depths where sea life outnumbers the plastics.

Raman spectroscopy is being used to distinguish between pure varieties and mixtures, and even identify the specific grape varietal.

Raman and XRF microscopies are used to study meteorites.

Fluorescence spectroscopy, Raman microscopy and particle size distribution analysis are used to characterise sunscreens.

Raman and photoluminescence spectral imaging are applied to reveal otherwise invisible spatial variation in chemical/crystal structure.

This application note details how Raman spectroscopy can offer quantitative and qualitative analysis of whisky samples.

This note looks at design options to optimise sensitivity, size and wavelength and how they can stretch the limits of applied Raman spectroscopy.

Hybrid Raman spectroscopy and SERS to detect analytes with low concentrations.

UV Raman allows fluorescence background to be eliminated entirely. This is explored in this application note.

This note describes the considerations in grating selection and how the user may prioritise them.

This paper discusses how and why the spectral resolution required for dispersive Raman microscopy depends on the intended application and the sample material.
