Thanks to rapid technology advancements in recent years, Raman spectroscopy has become a routine, cost-efficient, and much appreciated analytical tool with applications in material science and in-line process control for pharmaceutical, food & beverage, chemical and agricultural industries. This white paper discusses important performance parameters to consider when selecting a laser for Raman spectroscopy experiments

Traditional thinking is that compact spectrometers do not offer the sensitivity or speed needed to compete with benchtop fluorimeters for many fluorescence measurements. We explain how limit of detection (LOD) and limit of quantitation (LOQ) are defined and measured, and challenge that preconception by demonstrating picomolar LOD for fluorescein with a compact, cost-effective spectrometer capable of capturing 50 ms scans with ease.

Fluorescence spectroscopy has been used to characterise natural organic matter (NOM) in water. Excitation-Emission maps reveal the nature and concentration of NOM in river water and can be used as a routine analysis technique in water treatment facilities.
