The INVALCO HSS 1036 Hydro Surveillance System is a filter fluorescence photometer with a fixed excitation bandpass source (365 nm) and an emission bandpass filter (460 nm). It is designed specifically for the quantitation of low ppm concentration measurements of aromatic hydrocarbons (oil) in water.
The HSS 1036 uses a UV fluorescence technique to target the aromatic component of the oil contamination. Through a site calibration this aromatic tag provides an indication relative to total oil. The sample vial is placed into the sample well. A non-contacting UV light source targets the sample with filtered light energy. The soluble and emulsified oils in the water will excite from this light energy and fluoresce light energy back out of the water at a signature wavelength. The intensity of light energy at this wavelength is measured to provide an indication of the ppm concentration.
Features and Benefits
Solvent extraction qualifies sample to ISO and EPA methods
Fast sample preparation and immediate readings
Controlled and safe use of solvents
Easy calibration and instrument set-up
Reading printout serial port
Bright backlit display of ppm readings
Long life lamp

Performance
The performance is based on the site calibration to a known hydrocarbon concentration in stable background water. Changes in hydrocarbon make-up and background stability may affect the output. Through a simple calibration, this unit correlates well with laboratory ISO and EPA methods.
