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 challenging 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. MISA is a dedicated SERS analyzer that retains all of the appealing features of Raman – portable equipment, multi-analyte detection capabilities, and rapid analysis.
Simple and effective
Anyone can use MISA. A simple guided workflow gives you immediate answers when every minute counts:
- Prepare the sample with simple, target-specific methods
- Apply the sample to dedicated SERS test materials from Metrohm Raman
- Acquire the data with fully automated analyses
- Read and share results immediately
Food safety is just the start
Metrohm Raman has an established group of applications, which illustrate the practical application of the MISA platform for the analysis of common pesticides, food additives, artificial dyes and illicit materials found in everyday foods. The Application Notes provide recommendations for selection of material type (gold or silver), for a particular analyte as well as detailed step-by-step procedure for performing a test. MISA, in combination with the ID Kit and the SERS Library of Illicit Materials, can be used in the search for powerful hard-to-detect illicit drugs such as fentanyl. Look for new R&D opportunities with MISA in the near future.
MISA Cal and MISA Cal M
MISA can be operated using a computer, tablet, or mobile phone at the benchtop or at the scene.
Our MISA Cal software provides intuitive interface for easy SERS and Raman operating procedure and library building, as well as results viewing and reprocessing.
The MISA Cal M mobile platform provides wireless operation and results sharing, and can give MISA users immediate information about potentially dangerous substances to support immediate action.

Specific Smart Tips for SERS analysis
For sampling flexibility, MISA is equipped with Smart Tip attachments that are designed specifically for Metrohm’s SERS consumables.
- MISA Vial Smart Tip: accommodates glass vials for use with gold or silver colloids
- P-SERS Smart Tip: holds Metrohm P-SERS strips at optimal focal distance
SERS substrates for trace detection
SERS utilizes nanotechnology with Raman spectroscopy to enable trace detection of adsorbed molecules, this requires a SERS substrate. SERS substrates contain nanoparticles that enhance Raman scattering so that trace detection is readily achievable.
- High level of SERS enhancement, enabling detection of analytes down to ppb levels
- Highly reproducible SERS materials, which ensure consistent performance
- Easy to use format with step-by-step instructions for sample testing
- Adsorption of target compounds to the substrate offers some potential for sample separation
