 CINNAMINSON, N.J., Sept. 2 /PRNewswire/ -- DNA Plant Technology Corporation (NASDAQ: DNAP) today announced that its environmental diagnostics unit, Quantix Systems, is introducing a new version of its biotechnology-based Portable Workstation that provides rapid, on-site detection of contamination in water from diesel fuel, kerosene, home fuel oil and jet fuel. The work station previously detected these contaminants only in soil. The company also announced that it is introducing a new version of the Quantix LabStation that can now detect petroleum contaminants in water and soil samples, and offers laboratories an economical, high volume testing system.
 The water testing capability and new LabStation expand Quantix Systems' product line and are expected to lead to increased sales in the environmental remediation market.
 "The new tests will help regulatory agencies and environmentally responsible companies protect our water supply and the environment in a timely and cost-effective manner," said Steve Ludmerer, president of Quantix Systems. "We believe these new versions of the Portable Workstation and LabStation will help Quantix gain a significant share of the $100 million market for analysis of petroleum contamination in our environment."
 The Quantix (TM) Portable Workstation can analyze five samples in 15 to 30 minutes compared to the standard industry procedure of using off- site laboratories that generally take two weeks for results. The LabStation can test over 40 samples with 45 minutes .
 Both systems use a type of biotechnology called immunoassay technology. Immunoassay tests use antibodies which bind to specific targets, in this case petroleum contaminants. Immunoassay technology has also been used in human and animal health diagnostics since 1959 and is now a several million dollar business.
 The Quantix Portable Workstation product line was first introduced at the end of last year to measure gasoline contamination, detecting Benzene, Toulene, Ethylbenzene, and Xylene (BTEX) in soil and water. In July, the Portable Workstation was upgraded to also detect contamination in soil from polynuclear aromatic hydrocarbons (PAH) found in diesel fuel, kerosene, home fuel oil, and jet fuel. The Quantix LabStation was introduced in 1991 to detect pesticide contamination.
 The Portable Workstation has been used in remediation projects at petroleum distribution terminals, military bases, refineries, pipelines, airports, vehicle maintenance facilities, railroad right-of-ways, soil burning and bioremediation sites, and gasoline tank farms.
 The Portable Workstation and LabStation are the most sensitive immunoassays in the environment market. The Portable Workstation can quantify PAH in soil starting at 700 parts per billion (ppb) and in water at 100 ppb. The LabStation can quantify PAH at 500 ppb in soil and at 75 ppb in water.
 Quantix Systems is the environmental diagnostics unit of DNAP and is based in Cinnaminson, New Jersey. DNAP is a leading agricultural biotechnology company, applying a spectrum of technologies to develop and commercialize plant-based products and environmental diagnostic products for consumer and industrial markets. The company has two major operating joint ventures -- FreshWorld in premium fruits and vegetables and InterMountain Canola Company in special varieties of edible canola oil.
