Tiger Optics LLC is busy showcasing four of its newest laser-based products at the Pittcon Conference and Expo in Philadelphia this week.

The company is upgrading its entire line of standard analyzers and with devices like the HALO 3, HALO 3 H2O-500, HALO KA and the LaserTrace 2.5 all successfully on the scene for a number of years now, these four featured products and their upgrades are on show at Pittcon this week.

“With some of the predecessor products going on their sixth or seventh year, we’re thrilled to offer these significant upgrades to existing and new customers alike,” noted Lisa Bergson, Tiger’s founder and chief executive.

“With a detection limit of .3 ppb of H2O in helium, for example, the compact HALO 3 affords a whole new range of detection.”

Introduced in 2006, the original HALO was the brainchild of Dr. Farhang Shadman, the director of the influential Center for Environmentally Benign Semiconductor Manufacturing at the University of Arizona. At a meeting with Tiger, Dr. Shadman proposed a means to greatly reduce its product footprint, and the HALO was born.

Since then, Tiger has expanded this popular platform to include lower range and upper range versions, as well as HALOs for a multitude of molecules and matrices.

Today, the new HALO 3 H2O-500 provides a dynamic range, from 10 ppb to 500 ppm of H2O, traversing four orders of magnitude. For its part, the HALO KA, introduced in 2012, is “unique in its ability, as a compact device, to monitor extremely low levels of contamination in a UHP gas stream,” Bergson said. “Not only can the HALO-KA monitor moisture, but we also have systems available to monitor a wide variety of analytes in both inert and corrosive gases.”

As for the LaserTrace 2.5, which replaces the LaserTrace+, Bergson said the makers and users of ultra-high-purity gas will enjoy an advanced data filtration technique, resulting in a faster speed of response, as well as faster data acquisition and lower detection range in many gases.
