Contact SupplierInstrument Principal :
CHNS+O Analyzer is a new product, and it is used for oxygen,nitrogen, hydrogen, Carbon, Sulfur determination in ferrous and non-ferrous metals, rare earth materials, alloy, semiconductors, electronic materials, ores, ceramics, coal, graphite, and some organic / inorganic materials.
Instrument Specification :
1. Structure : Modular Structure, including electronic balance, computer, printer, high-frequency infrared carbon & sulfur analyzer, tubular resistance furnace, vacuum cleaners, water circulate chillers.
2. Detection System :
(i) Solid state Infrared detector is used for Oxygen. Thermo-conductivity detector is used for Nitrogen & Hydrogen.
(ii) IR Cell: Standard configuration of measure scope is composed of low carbon, high carbon and low sulfur. For specially required scope for sulfur, high sulfur can be added.
(iii) Detector: Solid-state pyroelectric detector.
(iv) Motor: Synchronous motor made in Swiss, continuously working.
(v) IR Emitter: Anti-oxide, stable IR emitter.
(vi) Temperature control: Keep constant temperature in the whole infrared unit to make sure the temperature of detected gas to be stable and the results to be accurate.
(vii) Protective gas: Controlled gas flow to purify and protect IR emitters and detectors, avoiding the influence of ambient to improve the stability and accuracy.
(viii) Thermo-conductivity (TCD) detecting unit: Anti-oxide NTC thermistor (ix) Signal processing: Small current control technique is developed to make sure the thermistors can be used without carrier gas (x) Reference gas circuit: Low flow control technique is used.
3. Gas flow control: High sensitive and accurate electric flow control technique based on the low pressure difference is applied, and Anti-Overshoot System is applied.
4. Catalyst unit : a) Catalyst heater: Convert CO to CO2 and SO2 to SO3. b) Filter: SO3 is removed by a filter, to ensure the tail gas reach the requirement of atmospheric environment protection.
5. Dust filter : Made of powdered metal technique, can be reused by washing in ultrasonic cleaner periodically. Cleaning filter and combustion chamber twice during one analysis by special design of the furnace, which reduce the difficulty of daily maintenance.
6. Weighing: Sample mass can be transfer from balance into computer automatically, If necessary, the mass can also be manual input.
7. Analysis time : A typical analysis using induction furnace requires 30-40 seconds.
8. Crucible Ceramic crucible using in induction furnace is 25mm in diameter.
9. Furnace: High frequency induction furnace, 18MHz, Max 2.7KVA, (Temperature: Max.3000o C)
10. Calibration: 1) Fast calibration 2) Normal calibration
11. Power: 220VAC 10%, 50/60Hz, current max. 50A.
