Have I selected the right laser for my Raman experiments?
November 20th 2019Thanks 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. Improvements in laser technology, detectors (CCDs and InGaAs arrays), and spectral filters (VBG-based notch filters), along with developments of new schemes for signal generation and detection, have aided Raman instrument manufacturers in overcoming the challenge of weak signals which has accelerated instrument development and market growth. In this white paper, we discuss important performance parameters to consider when selecting the laser for Raman spectroscopy experiments.
HydraMist – Simultaneous Cold Vapor-Pneumatic Nebulization Spray Chamber
November 14th 2019Glass Expansion’s new HydraMist spray chamber can be simultaneously used to determine As, Se, Sb and Hg via hydride generation, in addition to the determination of non-hydride forming elements using conventional pneumatic nebulization. The performance of the HydraMist was evaluated on an Agilent 5100 SVDV ICP-OES, and, when paired with a SeaSpray nebulizer, the detection limits for the hydride forming elements were improved between 15- and 50-fold without compromising the analytical performance of the non-hydride forming elements.
