S and N with ASTM D-5453, ASTM D-4629 and ISO 20846

The international regulations for low sulfur content in refined petroleum products such as gasoline or diesel are more and more demanding, and the levels are always pushing lower. HORIBA Jobin Yvon, a member of the HORIBA Group, offers the appropriate solution with the introduction of the SLFAUV21A series.

This new model SLFA-UV21 ANS is based on the principle of combustion of a fixed volume of sample in a tubular resistance furnace at 1100 °C. UV
Fluorescence is used to analyze the SO2 gas produced during combustion, and nitrogen is measured by chemiluminescence.

The SLFA-UV21 ANS, a Sulfur & Nitrogen in oil analyzer achieves a detection limit of 0.03 ppm S and 0.1 ppm N.
