The 405P model is perfect for taking samples of water into a beaker and getting a direct measurement of hydrocarbons / oils instantaneously, which have a low to medium API, i.e. < 50 API. It is simple to use and supplied with surfactant to give a homogenous mix for accurate readings. This model is perfect for applications where the expectation is just for lower API oils, i.e. produced water applications.

The 280P model is the preferred model for instant sample measurement of low and high API hydrocarbons (>50API) in water such as condensates, lighter refined hydrocarbons (diesel, naphthalene’s, etc….) and PAH’s. Its excitation wavelength is lower than the 405P and hence capable of measuring the lighter
hydrocarbons.

NOTE: This does not mean the 280P cannot also measure the lower API hydrocarbon; it can!

The 280C model is capable of doing two different measurements, traditional solvent extraction cuvette measurement and surfactant homogenised hydrocarbon measurement. Unlike the 405P and the 280P, the 280C does not use a dipped probe for measurement, it utilises standard quartz laboratory cuvettes. So samples are placed in the cuvette and measurement. Whether you want to use traditional solvent extraction methods, or surfactant homogenised samples, it doesn’t matter, the HT280C can do either.

One feature that all Inov8 Systems products share, is the measurement detector that is used – a spectrometer. A spectrometer can precisely measure the specific wavelengths of light emitted by a fluorescent sample. This is crucial because different compounds fluoresce at different wavelengths, and the ability to detect the emission spectrum helps identify the chemical composition or presence of specific substances. As can be see below, different hydrocarbons will emit different spectra.
