DIR operates without wet chemistry and requires no solvents; only one drop of oil is needed for analysis. In addition, the unit’s patented flip-top design speeds test preparation and cleanup. The route-based capability of the FluidScan Q1100’s operation allows the device to virtually eliminate mislabeled samples and long wait times for laboratory analysis. The results highly correlate to TAN and TBN laboratory tests conducted with ASTM D664 and D4739 titration methods and water tests with the ASTM D6304 Karl Fischer Titration method.
