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
The webinar, organised by MIRPHAB, presents the working principles, applications and existing capabilities of MIR chemical sensors in Europe, featuring Adam Piotrowski (VIGO Systems), Ana Gonzalez (EPIC/MIRPHAB) and Fabio Pavanell (Ugent/IMEC).
This webinar, organised by PIXAPP, focuses on the fundamentals of PIC-based devices and packaging, with presentations from Dr Ana Gonzalez (EPIC), and Dr Lee Carroll (Tyndall Institute).
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.
Measuring optical signals in the femtowatt (10-15) to nanowatt (10-9) range can be a daunting task. In order to achieve significant improvements in noise rejection we need to turn to a lock-in amplifier, which can improve noise rejection by 3 orders of magnitude or more.
