With working range that covers total nitrogen/sulfur/chlorine (NSX) from low-ppb to high-ppm concentrations, TITAN 4000 uses combustion method that caters to range of applications in refinery and chemical samples. Operation is in real-time, with TN/TS samples analyzed within 2 min and TX samples under 4 min, and requires minimal handling. Also included, chromium-plated copper spray injection design can inject high-boiling point component samples without blocking injection system.
