Measured Parameters

One of the advantages of the FluidScan over laboratory FTIR is its ability to report absolute quantitative results for critical properties such as TAN and water contaminations for industrial lubricants or TBN, water, glycol, and soot for engine oils. Below table specifies different parameters provided by FluidScan depending on the oil type. 
Application Categories Properties Measured by FluidScan
Transmission  Water (PPM), Oxidation (Abs/0.1mm), Fluid Integrity (unit)
Hydraulic - Fire resistant (Phosphate Ester) Water (PPM), TAN (mg KOH/g)
Hydraulic - Aerospace (Synthetic Hydraulic Fluid) Water (PPM), Oxidation (Abs/0.1 mm), Alien Fluid mineral based (MIL-H-2304) (%), and Alien Fluid engine oil (ML-H-23699) (%)
Heat Transfer (Quenching Oil)  Water (PPM), Oxidation (Abs/0.1 mm)
Industrial (Steam and CCGT Turbine, Hydraulic, Compressor, Chiller, Gear, etc.) Water (PPM), Oxidation (Abs/0.1 mm), TAN (mg KOH/g)

Multivariate Calibration

The FluidScan® classifies fluids into groups called families based on their chemical makeup, usage and spectral signature. The spectrum of all fluids in each family changes in a similar way with a given amount of degradation or contamination. Family-specific algorithms are assigned that accurately quantify these amounts. These algorithms yield quantitative results for the most critical properties of the most common oil types. Multivariate calibrations are applied so that quantitative readings can be obtained, even with complex, contaminated samples.
