Flame Spectroscopy
Flame spectroscopy is defined as an analytical technique that utilizes a flame to excite analytes, allowing for the determination of their concentration by measuring the emitted light at specific wavelengths.
Infrared Spectroscopy
Infrared Spectroscopy is the analysis of infrared light interacting with a molecule. This can be analyzed in three ways by measuring absorption, emission and reflection.
