Technical characteristics and parameters
1.Device characteristics and components
| Parameter | Description |
| Defined elements | Joint determination of carbon and sulfur |
| Principle of analysis | High Frequency Induction Furnace Combustion - Infrared Absorption Detection |
| Measuring range (quad cell detector) | Low carbon: 0.0001% – 0.2% High Carbon: 0.2000% – 10.0000% (expandable to 99.999%) Low sulfur: 0.0001% – 0.3% High sulfur: 0.3000% – 10.000% (expandable to 99.999%) |
| Sample weighing (standard steel sample) | Standard 0.5 g |
| Analysis accuracy | Complies with GB/T 20123-2006 standard Complies with ISO 15350:2000 standard Low carbon: ±1 ppm or ±0.5%; high carbon: ±10 ppm or ±0.5% Low sulfur: ±1 ppm or ±0.5%; high sulfur: ±30 ppm or ±0.5% |
| Sensitivity (minimum reading) | C/S: 0.1 ppm |
| Analysis time | 20 to 100 s (adjustable), typically 35 s |
| Operating mode | Continuous operation 24 h |
| High Frequency Induction Furnace | 1. Output power: 2500 W; oven temperature up to 2000 °C 2. Automatic leak test, alarm when time and current are exceeded 3. Adjustment of oven temperature by current/voltage/power/selected mode for different types of samples 4. Gas line: high-precision flow regulator to stabilize the gas flow; imported gas system |
| Dust filter | Metal filter with ultra-small pores of 0.4 microns, ensuring complete separation of dust from gas |
| Furnace head system | Automatic furnace head cleaning Heating the furnace head increases sulfur conversion, ensuring consistency of sulfur analysis results |
| Dust removal system | Automatic dust removal to reduce interference with analysis results High pressure dust removal - complete cleaning of pipelines |
| Detection system | 1. Circuit design: dual-processor modular design (upper and lower levels); the lower level uses the Atmega162 microcontroller; highly integrated electronic components ensuring reliability 2. Signal digitization: 24-bit ADS1224 ADC with high sampling accuracy 3. Layer-to-layer communication: USB 2.0 interface, providing high data transfer speed 4. Connection: Agilent 1521/2521 high-speed fiber optic cable (first used in China) is used between the IR detector and the high-frequency furnace, with multi-level shielding circuit to eliminate high-frequency interference 5. Power: Industrial linear modular power supply, providing stable output voltage without interruption 6. Radiation source: special platinum-iridium infrared lamp with constant heat dissipation and high radiation efficiency 7. Analytical cells: gold-plated cells for C and S with highly sensitive pyroelectric IR detectors 8. Motor: Stepper motor with high thermal stability and service life of 100,000 hours continuous operation |
2.Analytical software
| Parameter | Description |
| Operating software | Developed in Delphi; Full featured software in Chinese running Windows XP |
| Analytical channels | Channel management: ability to add, delete and edit channels for C and S without restrictions; presence of two channels for C and two for S (four detector cells), automatic switching between channels |
| Analysis functions | Dynamic integration of data during the analysis process; sampling rate of 20 measurements/s, which increases sensitivity and accuracy; sample management: editing names and identifiers, adding and deleting samples; multi-user mode with customizable access rights (administrator) |
| Data display | Two graphical windows (for C and S) with real-time display of all parameters and carbon and sulfur release curves |
| Data processing | Storing results in the ACCESS database (all data and curves for each analysis); flexible search by time, operator, sample name, identifier; functions for constructing and comparing calibration curves, correction of results, statistical processing, background subtraction, parameter settings, channel selection |
| Various printing modes (laboratory and control and inspection); ability to customize custom print format | |
| Self-diagnosis | System diagnostic function that allows you to programmatically check the tightness of the furnace head and gas cuvettes |
