Metrohm has developed the Misa, a handheld Raman spectrometer solution to detect and identify trace level food contamination in the field. Misa delivers rapid analysis of food samples in a few seconds, helping quickly identify threats to food safety.
The Misa enables enhanced analysis of a wide range of applications such as prohibited dyes, pesticide residues on fruits and vegetables, illicit pharmaceuticals mimicking traditional herbal medicines, and protein additives to diluted milk.
Traditionally, GM-MS and HPLC technologies have been used for food contamination analysis, however, the time, skill, and cost requirements limit their usage to the confines of well-equipped laboratories. Food analysis with Surface Enhanced Raman Scattering (SERS) is fast, convenient, and inexpensive. SERS combines nanotechnology with Raman spectroscopy to enable trace detection of contaminant molecules.
