Surface-Enhanced Raman Scattering (SERS) expands the capabilities of Raman spectroscopy
SERS measurements permit detection and identification of analytes at very low concentrations. It is a technique that is cross-compatible, with no system modifications, with all Raman instruments from Metrohm. Not only does SERS enable trace detection of analytes at very low levels, it can also be used to overcome fluorescence, for detection of multiple analytes in complex samples, and even quantitation using chemometrics.
SERS: The benefits
- Results in seconds
- Flexible choice of testing formats
- Easy-to-use format and step-by-step instructions for sample testing
- Customizable applications for your area of concern
- Automated workflows are available that collect the highest quality data and perform library matching
Complete trace detection solution
Detection of analytes present as a minority component in a mixture – whether at 10% or 10-7% – can be a complex, expensive, time-consuming, and technical laboratory-based task. SERS permits detection and identification of analytes in concentrations as low as parts-per-billion.
Trace analysis with SERS can be fast, convenient, and inexpensive. Metrohm delivers complete solutions for SERS measurements including instruments, sampling accessories, SERS materials, analysis software, libraries, method development, and support. Use your existing Raman system or assemble your own customized SERS solution.
The possibilities are boundless
SERS can be used with a variety of samples for many different applications:
- Narcotics detection: Fast, simple on-site sampling for instant identification of minor components.
- Pesticide testing: Detection of trace agricultural chemicals like pesticides, insecticides and herbicides.
- Food & Beverages: Authentication of foodstuffs including honey, olive oil, and saffron.
- Research & Development: Cost-effective, flexible tool that enables more accurate, faster, and less expensive measurements.
- Quality control: Fast and accurate results reduce downtime and increase productivity.
- Point of care: Instant detection of target samples in complex biological samples.
What is SERS and when is it applied?
The free white paper "Surface Enhanced Raman Scattering (SERS) – Expanding the Limits of Conventional Raman Analysis" explains the mechanism of SERS and how it can be applied to handheld Raman analysis with Metrohm Raman MIRA systems.
