Shandong Wanlianda Instrument Co., Ltd. has been focusing on analytical instruments for 30 years and become a leader in the field of domestic analytical instruments. Our high-frequency infrared carbonsulfur analyzer has 5 classical features: integrated design of highfrequency combustion furnace and infrared analyzer; two independent operating systems; reducing filter cleaning frequency significantly by using ultra-porous metal filters; more stable analytical gas flow by using gas mass flow controller; supporting wild measurement range including high-content carbon, low-content carbon, high-content sulfur and lowcontent sulfur.
computer for data processing, and finally print out the analysis results by a printer.

**Detailed explanation of installation requirements:**
1. Instrument placement requirements:
- The equipment should be placed on an insulated horizontal tabletop with a size of 240 cm. The tabletop needs to be able to accommodate three different instruments and a printer.
- The tabletop width needs to be 90cm and the height 75cm, and the table must be more than 50cm away from the wall to ensure ventilation and safe separation.
2. Indoor environment requirements:
- The room temperature should be controlled between 10 and 30 degrees Celsius, and the allowed temperature fluctuation does not exceed ±2 degrees Celsius. If this requirement cannot be met, air conditioning needs to be installed to maintain temperature stability.
- The indoor humidity should be kept below 80%. It is recommended to use a dehumidifier to reduce the humidity and prevent the instrument from getting damp.
3. Power supply requirements:
- The voltage needs to be stable at 220V, and the allowed fluctuation range is ±5%. If the fluctuation exceeds this range, a dedicated 5KVA voltage regulator must be used.
- The equipment needs to have a dedicated ground wire, and the ground resistance should not be greater than 4 ohms to ensure safety.
4. Gas supply requirements:
- The raw gas should be pure oxygen with a purity of 99.9% to ensure the accuracy of the experiment.
- Nitrogen or oil-free compressed air can be used as motive gas to ensure that the gas is pure and contains no oil.
5. Working environment requirements:
- The work area must be vibration-free to avoid interfering with the normal operation of the equipment, and dust-free to avoid contaminating the interior of the instrument.
6. Crucible handling requirements:
- Heat the crucible to above 1200°C in a muffle furnace and incinerate it for at least four hours, then cool it naturally and store it in a desiccator within eight hours until ready for use.
**Detailed description of acceptance test standards:**
1. Repeatability index test:
- Use the standard sample provided by Wanlianda Company with a carbon content of 0.5%-1.0% and a sulfur content of 0.045%-0.1% for seven consecutive measurements.
- The relative standard deviation (RSD) should be less than or equal to 0.4% for carbon and less than or equal to 1.0% for sulfur to ensure the stability and reliability of the test results.
2. Accuracy test:
- Carbon testing is divided into three concentration ranges:
- Use a standard with a carbon content of 0.01%-0.1% for calibration and then test another sample within the same range. The measurement error must comply with the JJG395-2016 standard tolerance.
- Use a standard with a carbon content of 0.1%-1% for calibration and then test another sample in the same range. Also ensure that the measurement error is within the allowable range.
- Using standards with a carbon content of more than 1% for post-calibration testing still needs to meet the error standard.
- The test of sulfur is also divided into two concentration intervals:
- Use a standard with a sulfur content of 0.01%-0.1% for calibration and then test another sample within the same range to ensure that the measurement error meets the standard.
- Use standard products with a sulfur content exceeding 0.1% for post-calibration testing, and the measurement error must also comply with the standard tolerance.
3. Acceptance confirmation:
- After all standard tests meet the above requirements, the user should sign and stamp to confirm the completion of acceptance.
Additional remarks:
- Standards used during calibration should usually have a higher concentration than the sample being tested to ensure accuracy.
- All standards used must be valid standards within the validity period and recognized by the department.
