16. 16 Specifications Method Compliance ASTM D5453, D6667, D4629, D5176, ISO 20846 Certifications/Area Classifications ATEX Ex px ia IIC T4 Gb Performance Analytical Range: 200 ppb for Sulfur and 250 ppb for Nitrogen (lower detection limit) to % levels Precision: within <1% of full scale, for most applications Linearity: 1ppm concentrations Analysis Time: 2 minutes; analyses over 1000 ppm may take longer Cycle Time: 2 to 5 minutes, programmable Communication Outputs 4–20 mA isolated at 750 Ω (standard) Discreet digital inputs and outputs for remote control and status indication RS-232, RS-422, RS-485 for Modbus RTU (standard) Modbus TCP/IP and Ethernet (optional) Sampling Injection valve, 2 or 5 µl sample volume; Sampling system available as recommended option Utility Requirements Carrier (Argon, Nitrogen*, Air): 99.975%, 50 psig, 5–15 cc/min Instrument or Plant Air/Oxygen for combustion (application dependent) Combustion gas (Oxygen, Air): 99.75%, 50 psig, 400 cc/min Plant Air (purge): clean, dry, particle-free; 80–100 psig Instrument Air: 80–100 psig, for injection valve operation and for pneumatic output to sample conditioning panel * Nitrogen cannot be used as carrier on a 6200 N Nitrogen system.

17. 17 Sample is introduced into an oxygen rich environment and combusted @ >1000°C. – Sulfur species converted to SO 2 ; – Hydrocarbons are converted to water vapor and CO 2 C x H y -S-N + O 2 (excess) = H 2 O+ CO 2 +O 2 +SO 2 +NO Or R- N + R-S + O 2  CO 2 + H 2 O + NO + SO2 Water vapor removed with membrane dryer – Reverse osmosis Pyro Oxidation of Sample Theory of Operation- Total Sulfur 1

18. 18 Oxidized sample is exposure to UV light – SO 2 Is converted to SO 2 * – On returning to stable state, energy is emitted as a flash of light which is measured by a photomultiplier tube – Amount of energy produces is directly proportional to the number of sulfur atoms in the sample SO 2 + hv = SO 2 * = SO 2 + hv Pyro UV fluorescence of Sulfur Theory of Operation- Total Sulfur 2

19. 19 Oxidized sample is Mixed with Ozone – NO Is converted to NO 2 * – On returning to stable state, energy is emitted as flash of light which is measured by a photomultiplier tube – Amount of energy produces is directly proportional to the number of bound nitrogen atoms in the sample NO + O 3  NO 2 *  NO 2 + hv Pyro Chemiluminescence's of Nitrogen Theory of Operation – Total Nitrogen
