Tiger Optics is deploying more gas analyzers from its HALO product line, amid increasing demand for its devices to monitor gas mixtures.
The HALO range of analyzers from Tiger Optics is distinguished by a number of key features, including fast response, high accuracy, wide detection range, and the capacity to evaluate many base gases.
The first HALO, introduced in 2006, was designed to offer the speed, specificity and reliability of the original Tiger tools at approximately half the price and one-quarter the size.
In 2007, Tiger unveiled the HALO+, designed to analyze moisture in gases down to ultra-low levels (0.4 ppb to 20 ppm) required in semiconductor fabrication plants.
This latest development, demonstrated at SEMICON West in July, signals yet another milestone for Tiger Optics, which holds exclusive rights to multiple, broad-based patents from Princeton University on Continuous Wave Cavity Ring-Down Spectroscopy (CW CRDS).
The latest addition, the HALO-500-H2O, permits a facility’s quality control lab to evaluate moisture levels over a very wide 20 ppb-500 ppm range, encompassing expected moisture values in most gas mixtures. Even under conditions where high moisture samples are followed by sub ppm level samples, the HALO-H2O and HALO-500-H2O can achieve 95% of a reading in less than three minutes, thereby assuring fast, highly accurate measurements and outstanding sample throughput in the lab.
Tiger analyzers detect the presence of fugitive components down to the low parts-per-trillion level in a variety of gases. Over the past decade, CW CRDS has advanced the analysis of many packaged pure gases, including inert gases, reactive gases (toxic gases, corrosives, and hydrides), and rare gases.
Lisa Bergson, founder and Chief Executive of Tiger Optics, said, “Water vapour is a common contaminant that can shorten the useful lifetime of packaged gas mixtures. Our HALO product line is a perfect fit for trace moisture analysis in quality control.”
A standard HALO analyzer includes a family ofsix base gases (argon, helium, hydrogen, oxygen, nitrogen, and clean dry air). The HALO gas menu can be enhanced with other base gases, such as carbon monoxide, carbon dioxide, fluorocarbons and sulfur hexafluoride, as well as gas mixtures. Options are also available for gas mixture samples that require compatible cell material (such as corrosion-resistant alloys) or specific operation settings (such as such as high/low flow or custom pressure range).
