Tiger Optics develops new analyzer for moisture detection in ammonia

Latest analyzer reduces the lowest detection limit to 2 parts-per-billion

Gas analyzer manufacturer, Tiger Optics, has developed a new analyzer that, the company says, refines the detection of moisture in ammonia to levels down to 2 parts-per-billion (ppb), achieving five times the sensitivity of incumbent technology.

Just five years ago, Tiger introduced its original ALOHA H2O analyzer for the fast-growing High Brightness Light Emitting Diode (HB LED) market. With that, Tiger met the industry's need to detect moisture in ammonia at levels to 10 ppb, as higher concentrations impair the electroluminescent intensity of HB LEDs and diminish process yields. This directly affects profit margins as brightness determines whether an LED finds use in a flat screen TV or is relegated to the nose of a child's toy.

With the new ALOHA+ H2O analyzer, Tiger Optics continues to address the needs of HB LED makers, tool manufacturers, purifier makers and the gas companies that supply ammonia, the favoured source of nitrogen for the production of gallium nitride (GaN) semiconductor wafers, a core component of HB LEDs.

The compact ALOHA+ H2O analyzer fits two to a 19'-inch rack and features Tiger's laser based technology. Often used in remote locations, where skilled technicians and support services are hard to come by, Tiger's products require little maintenance and are easy to install and to operate.

Founded in 2001, the Pennsylvania-based company has earned its reputation for detecting trace levels of moisture in bulk and specialty gases. "When we entered the moisture in ammonia analysis market back in 2004, we did so with an analyzer that had the lowest detection limit available. Since then, the "˜Lowest Detection Limit' (LDL) is a title that we have maintained," said Lisa Bergson, Tiger Optics' founder and chief executive. "We've developed close relationships with the leading gas manufacturers, purifier makers and end-users of ammonia. When they told us that they needed an analyzer that had limits lower than even our best analyzer, we developed the ALOHA+ H2O analyzer and reduced the LDL to an astonishingly low level of 2 ppb."
