H2scan Corporate Presentation at ISA's 53rd Analysis Division Symposium Selected as One of Three Best Papers


VALENCIA, CA--(Marketwire - April 28, 2008) - H2scan Corporation today announced that a technical presentation detailing capabilities of the company's hydrogen sensor technology was selected as the third best paper at the ISA's 53rd Analysis Division Symposium held in Calgary, Alberta, April 20-24, 2008. The symposium, which focuses on new and innovative analytical solutions for process control & compliance, is attended by industry professionals from around the world, and over 30 pre-screened papers were presented for review and rating by this symposium. The paper was authored by Prabhu Soundarrajan, An Nguyen Le and Dr. Todd Wilke, H2scan's Chief Technical Officer.

Hydrogen is an important gas used in petroleum refining and chemical production, but direct measurement of hydrogen for optimum control has been limited by available sensing technologies. H2scan's hydrogen sensors enable new process monitoring and control applications because they offer both enhanced capabilities and a reduced total cost of ownership. H2scan's sensing technology is fundamentally specific to hydrogen and is therefore not affected by the presence of many background gases such as H2O, hydrocarbons and CO2. H2scan's sensors also have a proprietary coating over the sensing elements that allows for continuous operation in the presence of contaminants such as H2S and CO which negatively affect other sensors. As a solid-state device, H2scan's hydrogen sensor is also a cost effective solution since it has no moving parts or consumables and has a 10 year product life expectancy.

The ISA is a global organization with over 30,000 members worldwide founded in 1945 dedicated to the advancement of instrumentation, systems and automation in all industries and applications.

H2scan is the leading provider of high performance hydrogen specific sensor systems which provide accurate monitoring and control functions for a wide range of applications, including control systems, safety monitoring and alarm systems. H2scan also provides portable, hand-held configurations for easy leak detection and monitoring.

About H2scan (www.h2scan.com)

H2scan is the leading provider of high performance hydrogen specific sensor systems which provide accurate monitoring and control functions for a wide range of applications, including control systems, safety monitoring and alarm systems. H2scan also provides portable, hand-held configurations for easy leak detection and monitoring.

H2scan's hydrogen specific sensing systems based on a patented "Chip on a flex" technology are able to detect and measure hydrogen without false readings or expensive support equipment required. The sensing systems are able to detect hydrogen in air down to 15 ppm concentration over a wide range of temperatures without cross-sensitivities to other gases. The ability to operate in the presence or absence of oxygen with no interference with CO, sulfur, or chlorine separates H2scan from all other in-line measuring technologies.

The company's solid-state technology was developed at the U.S. Department of Energy Sandia National Laboratory and is only available commercially through H2scan.

H2scan Corporation is headquartered in Valencia, California, and was formed in 2002 with capital assistance from the Ravinia Venture Fund and Vancouver-based Chrysalix Energy Limited Partnership, which includes Ballard Power Systems Inc., Shell Hydrogen, The BOC Group, BASF Venture Capital and Mitsubishi Corporation.
