INFRARED SPECTROSCOPY | Sample Presentation

摘要: Mid-infrared spectroscopy is a very important and widely used sample characterisation analytical technique, whether the in form of gas, liquid, paste-like, or solid. The technique extensively applications involving qualitative analysis, providing either functional group structural information about its composition fingerprint spectrum (identification) material. This article covers preparation presentation methods, both traditional many more recently developed practiced, analyses by mid-infrared spectroscopy. It transmission, reflection (both internal external), photoacoustic, emission sampling methods.
