Have I selected the right laser for my Raman experiments?

This article is brought to you by: 

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

Scaling spectroscopy

Matthew Dale discovers how scaling spectrometers down to the chip level enables them to be mass-produced in standard MEMS foundries, making spectroscopy more affordable for various new applications

Challenging the Limit of Detection of Compact Spectrometers

This article is brought to you by: 

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.
