The HydraMist spray chamber features:
The same outstanding short-term analytical precision and washout as other Glass Expansion cyclonic spray chambers
Fast and complete vapor phase formation of volatile As, Se, Sb, Tl, and Hg species for the best detection limits in hydride generation mode
A unique drain design to eliminate hydrogen build-up and sample reflux that degrades short-term precision
Economic, just replace your current spray chamber and keep your existing nebulizer
Improve productivity by analyzing non-hydride forming elements and cold vapor elements simultaneously, avoiding system shutdowns to change over between the hydride generator accessory and conventional pneumatic nebulization
Simple to setup with fast changeover, the HydraMist Spray chamber can be operated in one of 3 different modes. The simple mode provides (figure 1.) simultaneous hydride and pneumatic nebulization mode with 5 fold improvements for detection limits of the hydride forming elements while maintaining analytical performance for non-hydride elements. With the addition of an extra sample input and t-piece (figure 2.) the HyrdraMist provides a sensitive, simultaneous cold vapor and pneumatic nebulization mode with more than 10 fold improvements in detection limits for the cold vapor elements without compromising the performance of non-hydride forming elements. Finally, it can be used as a conventional cyclonic spray chamber with pneumatic nebulization.
