Ocean Optics has introduced a new substrate for Raman spectroscopy applications. Surface Enhanced Raman Spectroscopy (SERS) substrates are highly sensitive, stable and reliable, delivering precise trace-level Raman spectroscopy measurement in applications ranging from chemical and explosive agent detection, to authentication, contaminant screening and quality control in production environments and the laboratory.
Using precisely controlled gold nanoparticles, Ocean Optics SERS substrates amplify very weak Raman signals by many orders of magnitude. The result is fast, repeatable SERS measurements for the identification and quantification of SERS-active analytes. Detection at the parts per billion and even parts per trillion level are possible.
Ocean Optics’ SERS substrate manufacturing method results in affordable mass production with high repeatability and customisation options. Standard substrates are microscope slide format with a 5mm diameter active area. The company uses optical-grade borosilicate glass and high-performance silicone-based adhesive for compatibility with a wide range of solvents. Customised designs are available on demand with choice of form factor such as swabs and coatings, as well as the ability to impart specificity to particular analytes.
SERS substrates work reliably with the complete range of Ocean Optics Raman instruments, including the IDRaman mini handheld Raman spectrometer.
