The calibration specification of sulfur dioxide analyzer is a key step to ensure the accuracy and reliability of measurement results. The following is a detailed calibration specification based on search results:
1. Preparation before calibration
Instrument inspection: Ensure that the appearance of the instrument is undamaged and that the functional modules (such as touch screen, voice broadcast system, and pipeline connections) are functioning properly.
Environmental control: The calibration environment should meet the requirements of temperature (recommended 20-25 ℃) and humidity (40-60% RH), while avoiding strong electromagnetic interference.
Standard substances and equipment: Use traceable standard sulfur dioxide solution or gas, and the calibration range should cover the nominal 0-50mg SO ₂ range of the instrument. Recommend using a nitrogen generator or steel cylinder to optimize calibration conditions.
2. Core calibration steps
Zero point calibration and baseline correction: Start the instrument in a sulfur dioxide free environment and ensure that the initial reading is zero by using the built-in zero adjustment function or manually adjusting the potentiometer. The intelligent voice prompt system can assist operators in completing the zeroing process.
Multi point linear calibration: Inject standard solutions of different concentrations (such as 10mg, 25mg, 50mg SO ₂) separately, and record the instrument response values. Calibration should cover the actual detection range (such as the typical content range of samples such as preserved wine and grape wine), and verify whether the linear error of the instrument is ≤ 4%. According to the requirements of GB5009.34-2022, use sodium sulfite solution for recovery rate testing to ensure that it is ≥ 85%. The automatic distillation compensation function can reduce human error and improve the reliability of recovery rate.
3. Confirmation and recording after calibration
Data comparison: After calibration is completed, the measured values need to be compared with the standard values. If the error exceeds the allowable range (such as repeatability RSD4%), pipeline blockage or sensor sensitivity issues need to be investigated. The self checking system can automatically prompt abnormal states.
Record keeping: Record the data and results during the calibration process, and save relevant files and records [3].
4. Calibration frequency
Zero point calibration: It is recommended to perform zero point calibration every time the instrument is turned on to eliminate possible zero drift that may occur during prolonged shutdown or use. Calibration instrument
Range calibration: Generally, range calibration is performed every 1-3 months. If the instrument is frequently used or requires high accuracy of the test results, the calibration cycle can be appropriately shortened.
Linear calibration: Linear calibration is generally performed once a year, and it is also necessary to perform linear calibration when key components of the instrument are replaced or when there is a significant deviation in the measurement results.
5. Maintenance methods
Regular cleaning: Use a clean soft cloth to wipe the outer shell of the instrument regularly to remove dust and stains. For stubborn stains on the surface of the instrument, a mild cleaner dipped in a soft cloth can be used to gently wipe, but it is important to avoid liquid entering the interior of the instrument.
Internal cleaning: According to the instrument's user manual, regularly open the instrument's casing or detachable parts, and use a clean brush or compressed air to remove dust and debris from the interior. For optical components such as light sources, lenses, etc., specialized optical cleaning cloths and cleaning agents can be used for wiping to ensure smooth optical paths and accurate transmission of optical signals.
Through the above calibration standards, the accuracy and reliability of the sulfur dioxide analyzer can be ensured, providing strong support for the environmental management and safety production of enterprises
