detection limit) to % levels
• Precision: within <1% of full scale, for most applications
• Linearity: <1% of full scale at >1ppm concentrations
• Analysis Time: 2 minutes; analyses over 1000 ppm may take longer
• Cycle Time: 2 to 5 minutes, programmable
• 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)

•
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.

Theory of Operation- Total Sulfur 1
Pyro Oxidation of Sample
•
Sample is introduced into an oxygen rich environment and combusted @ >1000°C.
– Sulfur species converted to SO2;
– Hydrocarbons are converted to water vapor and CO2
CxHy-S-N + O2 (excess) = H2O+ CO2+O2+SO2+NO
Or
R- N + R-S + O2  CO2 + H2 O + NO + SO2
•
Water vapor removed with membrane dryer
– Reverse osmosis
17
Theory of Operation- Total Sulfur 2
Pyro UV fluorescence of Sulfur
•
Oxidized sample is exposure to UV light
– SO2 Is converted to SO2*
– 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
SO2 + hv = SO2* = SO2 + hv
18
Theory of Operation – Total Nitrogen
Pyro Chemiluminescence's of Nitrogen
•
Oxidized sample is Mixed with Ozone
– NO Is converted to NO2*
– 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 + O3  NO2*  NO2 + hv
