Very recently we have acquired SERS substrate from SERSitive for our research work on detection and analysis of gaseous compounds through detection of Raman signals from the samples. Our preliminary investigation with standard Raman active samples reveal that the SERS substrates are highly reproducible. Furthermore, it provides acceptably high enhancement factor (˜106). The technical team of SERSitive are very supportive and always ready to extend its support whenever required. I strongly recommend SERS substrate from SERSitive which offer its products at a very competitive price.
