Key WordIndustryApplication TitleDescription
APHAPetroleumOn-Line Monitoring of APHA ColorAPHA is sometimes referred to as the Platinum- Cobalt (Pt/Co) or Hazen scale. Also referred to as a “yellowness index”, the APHA color scale is a common method of comparison of the intensity of yellow-tinted samples to assess the quality of liquids that are clear to yellowish in color. Discover how real-time monitoring of APHA color either on-line or in a laboratory setting using a photometer can improve your process.

PetroleumMonitoring the Percent Aromatics in Gasoline by NIRThe aromatic content of gasoline determines many of its combustion properties. Since it also impacts the environmental characteristics of the fuel it is desirable to have accurate measurements of this parameter. The traditional analytical method for measuring aromatics is either gas chromatography (GC) or an older method entitled fluorescent indicator adsorption (FIA), both of which are time and labor intensive. Learn how Guided Wave hardware and software can provide real-time measurement of % aromatics in fuel products using fiber optic-based, Near-Infrared (NIR) spectroscopy.
ASTM Color / D1500 / D1524
