Recent field developments and new applications led to the introduction of an additional optical channel for the existing very successful TD-500. The dual-channel design makes the TD-500D applicable to a wide range of hydrocarbon types and concentrations. Channel "A" has the same optics as the original TD-500 and the new Channel "B" is for heavy crude oils or applications that require an increased measurement range without solvent dilution. The new channel "B" eliminates the need for sample dilution even with crude oil concentrations over 1000ppm. Channel A can be used for gas condensates and refined oils and fuel such as diesel from over 1000ppm to below 1ppm.
The TD-500D handheld oil in water analyzer was initially developed for offshore oil applications including produced water, deck drains, and bilge water and is now being used for oil spill response and many other oil in water analysis applications. In the recent months the TD-500 was deployed at four major oil spills in the US and Canada. Special very simple field sampling methods are being developed by Turner Designs Hydrocarbon Instruments for the TD-500D for enforcement of international oily bilge water discharge laws. The United States Coast Guard (USCG) was one of the first customers.
The TD-500D is compatible with all popular solvents used for solvent extraction and evaporation is not required. In addition, Turner Designs Hydrocarbon Instruments is developing a new environmentally friendly solvent free method.
