Mini-Z Sulfur


Inspect petroleum fuels for ultra-low sulphur levels (ULSD)


  • Direct measurement without sample preparation
  • Established method: ASTM D-2622
  • Very low limit-of-detection (LLD): 0.26 ppm
  • Wide analysis range (LOQ): 0.78 ppm to 4 wt%
  • Standard deviation of 0.18 ppm at 10 ppm
  • Fast measurement time: 300 seconds
  • High throughput: 6-position autosampler
  • No combustible gases required
  • Built-in computer, keypad, and display
  • Extremely low maintenance


The compact benchtop Mini-Z Sulfur analyzer is meant for non-technical employees to operate and is specifically built for rapid batch testing of low and ultra-low sulphur diesel (ULSD) and gasoline fuel samples. The rugged design is hardened for industrial operation with little maintenance, whether at petroleum pipeline terminals, refineries, or testing facilities.

Sulfur analysis without gas using regular power

The Mini-Z Sulfur analyzer has several advantages over competing products and technologies, including an unrivalled lower limit-of-detection, a wide analysis range, and the greatest repeatability in the market. It runs on regular 110 VAC (USA) wall power and does not require combustible gases (other voltages and frequencies are supported too).

ASTM D-2622, ISO 20884 and JIS K 2541-7 compliance

With a range of 0.26 ppm to 4 wt percent, the Mini-Z Sulfur analyzer meets the most common international standards for low sulphur readings, including ASTM D-2622, ISO 20884, and JIS K 2541-7.
