Abstract
Disclosed is a combination of a Fabry-Perot Tunable Filter (FPTF) wavelength selector, an internal reflection element (IRE) capable of measuring Attenuated Total Reflectance (ATR) spectra, and a pressure application element for applying pressure to samples, if needed. The resultant portable and compact device is called an FPTF-ATR spectrometer. The device measures data that can be used to identify chemical species in samples, predict properties of samples, and quantify amounts of chemical species in samples. Also disclosed are methods for using the FPTF-ATR for analyzing samples, especially analyzing compounds containing cannabis, hops, and other chemical species where portable chemical analysis is important.
