Ocean Optics Surface-enhanced Raman spectroscopy (SERS) substrates let you make fast, repeatable measurements for the identification and quantification of SERS-active analytes. Typical applications include trace level detection of narcotics, pesticides and taggants. Now, new improved SERS substrates offer extended shelf life of eight months, a significant improvement over the previous 30-day or six-week limits. This change greatly reduces time pressure for users.
Product Overview
Reproducible: Repeatable substrates allow for confidence in detection and quantification with concentration regressions.
Stable: Long shelf life relieves pressure on test scheduling. Each slide offers four large active SERS chips with clear serialization.
Robust: Signal Enhancing Heat Sink allows wide range of laser power without compromising substrates.
Specifications:
Raman Laser Excitation Wavelength Range: 671 / 785 / 830 / 1064 nm
Key Applications:
Detection of narcotics. Fast identification of drugs in the field is a real boon for those combating drug-related crime. Often only small residues of a sample can be collected from a crime scene. SERS also opens up a potential route for fast roadside drug screening of drivers using saliva samples.
Food safety. Certain additives such as melamine found in milk powder can be extremely harmful even at very low concentrations. Using SERS, we can qualify and quantify the level of dangerous trace elements in our food supply chain.
Anti-counterfeit tagging. High value products that are subject to duties and taxes — petrol is one example — are often the target of piracy and fraud. By adding a small amount of a SERS-active taggant to the unadulterated product, detecting the taggant becomes an instant indicator of authenticity.
