J.U.M.'s FPM 605 reliably detects diesel oil, jet fuel and all other PAH-containing oils in water. The FPM 605 is a continuous, on-line, process or field monitor which provides the reliable measurement of low to medium ppm concentrations of dissolved or emulsified oil in water. It is used for applications which require oil monitoring in treated and untreated water streams. This could be from industrial wastewater, groundwater, process water, produced water and storm/rain water run-off.

Continuous monitoring of oils as PAH (Poly- Aromatic Hydro- carbons) is a reliable, effective, and well recognized method to improve the process management for treating, discharging and detecting oils in water. Compared to the laboratory grab sample analysis method, the technique of continuous on-line monitoring provides cost effective, remote and operator unattended measurement of poly aromatic hydrocarbons in water.

The FPM 605 is based on the chemical principle that poly aromatic hydrocarbons absorb light energy at one UV- wavelength (called exication) and emit light energy at some longer UV- wavelength (called emission). This process is named UV fluorescence. Such fluorometer only detects hydrocarbons (and other materials) which fluoresce with the selected pair of exication and emission wavelengths. The fluorometeric detection of PAH's is a sensitive, selective and specific method, which is nearly immune to air bubbles and suspended solids that are often present in the water to be measured.

With our proprietary open cuvette flow cell, the FPM 605 does not use a glass flow cell. The hydrocarbons are detected in a stream of water which smoothly overflows our flow cell. The water stream cannot contact, contaminate or foul the optical windows which are used for the detection. No chemicals, no pretreatment and no manual manipulation of the water sample are required to monitor poly aromatic hydrocarbons.

Major Applications to be found in:

• Cooling Water
• Oil Coolers
• Oil Separators
• Condensers
• Heat Exchanger leak detection
• Fluorescin Tracer Detection in Cooling Water

• Continuous monitoring means uninterrupted real time measurement of PAH's in contaminated water
• Direct measurement does not require any sample pretreatment like extraction prior to measurement. The FPM 605 does not require the use of solvents to monitor oil in water
• Monitoring process is more selective for the detection of oils in the presence of physical and chemical interference in contaminated water
• Non-contact flow cell minimizes routine cleaning procedures of the optical circuit
