Total Organic Carbon Detector

Biological Aerosol Threat Warning Detector

Measuring the total organic carbon (TOC) in water samples has multiple applications, such as identifying when foreign matter is added. Most inorganic compounds have a detectable level of organic carbon when added to a water system. Current TOC analysis technologies require a combination of hazardous reagents, high temperatures, and compressed gasses. In addition, such devices are highly sensitive to environmental factors, vibration, and user adjustments. OI Analytical developed an inexpensive, online, total organic carbon detector to quantitatively measure all types of organic carbon dissolved or suspended in water. The system can be used in field water or domestic water supply systems to detect contamination with organic substances. The OI Analytical detector provides a novel TOC analysis device packaged in a robust, field-installable, continuous monitoring package. The Environmental Protection Agency tested alpha prototypes of the system and identified hardware and software improvements. Selected water utilities field tested beta prototypes through the end of 2009. For additional information please fill out the Contact Information Form.
