Analysis method: The sample is burned or decomposed at high temperature to convert the tested element into gas for analysis. The gas is separated by adsorption analysis method and then detected by three pairs of ultra high sensitivity TCD.
Operation mode: CHNSO,CHNO,CNSO,CHNS,CHN,CNS,CNO,N,S,O.
Combustion temperature: 1800 ℃
Reduction temperature: 600 ℃
Detection range: 100ppm-100%
System sensitivity: ±1uV
Sensitivity analysis: less than 1ug
Automatic sampler: 64 wells,
Calibration: Single point calibration, multi-point calibration, linear to 4-level nonlinear regression, long-term stability.
Analysis time: less than 5 minutes for a single test
Gas:
Helium (He): 99.995% purity; Dosage: less than 500ml per analysis.
Oxygen (O2): 99.995% purity; Dosage: less than 30ml per analysis.
Compliant standards: ASTM D5373-93, ISO/TS 12902, ASTM D5291-91, DIN/ISO 13878, ASBC, AACC, AOAC, etc
The horizontal injection system completely removes the combustion products each time, without introducing systematic errors caused by sample combustion residues
Perfect sealed combustion system, patented technology combining dynamic and static combustion. The greatly improved combustion efficiency results in very low oxygen consumption.
Modular design that can meet the diverse needs of different users from multiple perspectives
