Electronic nose in alcohol applications

Among the pattern recognition methods of electronic noses, principal component analysis (PCA) is one of the commonly used methods. However, principal component analysis eliminates the correlation between variables (corresponding to the measurement sensors of the electronic nose) in the calculation p---

FT-IR and Raman Microscopy on a United Platform

The laser Raman spectrometer and the FT-IR infrared Raman spectrometer are organically integrated into the same system, so that complete spectral information can be obtained, and the size and cost of the instrument are reduced. In particular, because the system uses a "co-point" technique,---
