H2scan Corporation to Display New Hydrogen-Specific In-Line Process Monitor and Senior Scientist Prabhu Soundarrajan to Present at Global Petroleum Show in Calgary, Canada

VALENCIA, CA--(Marketwire - June 3, 2008) - H2scan Corporation, in conjunction with Westech Industrial Ltd. of Canada, announces their participation in The Global Petroleum Show in Calgary, Canada, June 10-12, 2008. Situated in booth # 1885, H2Scan will be giving a live demonstration of their HY-OPTIMA™ 700 hydrogen-specific, real-time, in-line process monitor.

Using a hydrogen-specific sensing element and its patented chip-on-flex technology developed by H2scan, the HY-OPTIMA is the only solid-state sensor technology that accurately measures hydrogen concentrations from 0 to 100% H2 on a volume basis in multiple gas backgrounds -- nitrogen, oxygen, and inert gases. The system operates in process gas temperatures of -20°C to +100°C and in 95% RH environments and handles flow rates of 0.1 to 50slpm and pressures up to 100 psi gauge. An onboard temperature sensor maintains the sensor at a constant temperature to maximize stability. The system offers interface flexibility including 0-5Volt, 4-20mA outputs with optional ASCII, RS-232, and RS-422 serial buses. H2Scan also offers the HY-OPTIMA 1700 series which is both ATEX and cLC "Intrinsically Safe" Certified.

The HY-OPTIMA 700 series, including the 730 and 740, with its cost-effective integration, is ideal for petroleum refineries, hydrogen production and petrochemical applications where real-time measurements can enhance plant efficiency. The system, which is calibrated on-site, offers plants in-line, real-time measurements for petroleum refineries, hydrogen production at petrochemical plants, chlorine producers, gas producers, nuclear and fossil fuel power plants, semiconductor and electronics manufacturers, hydrogen refueling stations, etc. These measurements can include in-line monitoring of H2 feed, process gas, feed-to-stack, recycle gas, and stack gas (vent) H2 concentrations, plus real-time backup to GC/GC-MS/MS, and off-line monitoring of H2 in grab samples.

Prabhu Soundarrajan, Chief Scientist of H2scan, will be presenting a paper on "In-line Hydrogen-Specific Sensors for Operations and Cost Reduction Measures in the Petroleum Industry" on Wednesday, June 11th during the afternoon Operating and Capital Cost Optimization Session.

The H2scan hydrogen-specific technology used in the HY-ALERTA™500 Handheld Leak Detector and the HY-ALERTA™600 Area Monitor will also be demonstrated at booth # 1885. These unique and dependable products are being used by companies worldwide to ensure the safety of their workers and their property.

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.
