July 18, 2007 - Tiger Optics LLC has unveiled at SEMICON West the HALO+, a mini-cavity ring-down spectroscopy (CRDS) analyzer capable of measuring at parts-per-trillion (PPT) levels. Sibling to Tiger's HALO, the new HALO+ is a compact CRDS tool that can analyze moisture in gases down to ultra-low levels.

The HALO+ addresses the heretofore-unmet need for fast, accurate, calibration-free measurement of moisture in the parts-per-trillion (PPT) to parts-per-million (PPM) range. The HALO+ is suited to many challenging processes where accurate moisture measurement is particularly critical, including fixed bulk gas continuous quality control, portable mobile analytical carts, process tool monitoring, air separation and gas cylinder quality control.

Designated as a transfer standard by many of the world's leading national laboratories, and addressing over 400 points worldwide, Tiger's analyzers are based on an absolute principle -- the Beer-Lambert Law, where the analyzers do not require costly and frequent calibration. Plus, they require no consumables and are robust and durable, as well as easier to operate than most measurement solutions
