Petroleum hydrocarbons analyzer AE-2 is designed for continuous automatic monitoring of content of petroleum hydrocarbons in potable, natural, and waste water. The instrument comprises a sample preparation unit and a fluorescence detector. The sample preparation unit provides metered water feed and switching of the water and reagent flows, control of temperature, mixing and mass-exchange processes. The detector (or optical cell) performs the detection of fluorescence of petroleum hydrocarbons extracted by hexane from the sample using a patented chromato membrane technology.

The analyzer is installed stationary and is controlled using a built-in microprocessor or an external PC. In a stand-alone operating mode, the selected reaction sequence can be assigned from a built-in keyboard. A firmware allows assigning any sequence of operation of system components and altering the flow rates from 0.02 to 20 ml/min. The instruments are equipped with a 4-20-mA current loop and RS485 computer interface for customized report output and remote computer control. Concentration measurement results, up to 1000 values, are stored in a built-in memory and are displayed, in milligrams per liter, on a built-in digital LC display. If concentration of petroleum hydrocarbons exceeds a threshold level, the alarm mode is activated and a relay may be triggered following a command from the analyzer.

Typical measurement cycle duration is 5 - 15 min (depending on concentration of the analyzed sample).

Is based on the measurement of fluorescence intensity that is  proportional to the concentration  of the TPH.
