RX-620SA determines total sulfur in petroleum products, such as gas oil, fuel oil, crude oil and naphtha, using energy dispersive X-ray fluorescence(EDXRF) method, which is an accurate, non-destructive, economical and yet quick method prescribed in ISO 8754 and ASTM D4294-03. Once a sample is set, the total sulfur is determined automatically in 300 seconds(typical).
The model RX-620SA is a 12-sample carousel model. After its successful predecessors, this fourth generation has been developed to further improve the accuracy and ease of use.
