Application Note: Total Chlorine by Modified ASTM D7536 with Accu-flow
19 February 2019

X-ray Fluorescence (XRF) spectrometry, while widely used for total sulfur testing, has traditionally been an ineffective tool for the direct measurement of total chlorides in crude oil due to the settling effects of inorganic chloride salts during the measurement process. This settling leads to poor precision and an industry preference for other measurement or sample extraction techniques.
