Described as offering ultra-low detection at a compelling price, Tiger Optics has introduced the new powerful HALO-KATM analyzer, capable of detecting traces of contaminants to 200 parts-per-trillion in an ultra-high-purity (UHP) gas stream.

Not just small in price, the HALO-KA features the smallest footprint of any high-purity analyzer in the market, the company claims, and thereby providing additional savings.

With a low detection limit of 500 ppt H2O in nitrogen (200 ppt in helium), two of the new instruments will fit in a 19-inch rack. Moreover, its powerful, patented principle of operation, Continuous Wave Cavity Ring-Down Spectroscopy (CW CRDS), requires no moving parts or calibration, saving on downtime, labor, and consumables. With such environmentally friendly features, the HALO-KA offers another advantage to fabs concerned with their overall carbon footprint.

The HALO-KA is the latest addition to a platform that debuted in 2006 as the HALO, a ‘mini’ device measuring moisture in a range from 2 ppb to 20 ppm, offering the speed, specificity and reliability of the original Tiger tools at approximately half the price and one-quarter the size. Notably, the original HALO was conceptualized by Dr. Farhang Shadman, the respected director of the NSF/SRC Engineering Research Center for Environmentally Benign Semiconductor Manufacturing at the University of Arizona.
