Introduction
GBT 34322-2017 Standard Overview
GB/T 34322—2017 is a national standard for the automatic and continuous determination of conductivity, pH value, phenolphthalein alkalinity, total alkalinity, chloride ion and hardness in industrial boiler water, circulating cooling water and natural water. It uses a multifunctional automatic potentiometric titrator combined with a variety of sensors for accurate measurement.
Standard Framework Comparison
| Standard Dimensions | GBT 34322—2017 | International Integration Degree | Technical Innovations |
|---|---|---|---|
| Potentiometric Titration | Core determination method, suitable for multi-parameter continuous detection. | Aligned with ISO standards, optimized automation process. | Introduced dynamic titration mode and preset endpoint titration technology. |
| Conductivity measurement | Range 10~10 mS/cm, high resolution. | Meet global laboratory water standards. | No calibration required, direct online measurement. |
| pH value detection | Applicable range 3~13, support high temperature measurement. | Consistent with international environmental protection requirements. | Optimized buffer solution ratio. |
Technology Implementation and Innovation
Dynamic titration mode: By automatically adjusting the amount of dripping, the determination accuracy of low-content samples is significantly improved.
Preset endpoint titration method: In the determination of phenolphthalein alkalinity and total alkalinity, pH values of 8.3 and 4.4 are used as endpoints, respectively, to achieve precise chemical metrological control.
Instrument modular design: Supports simultaneous measurement of multiple electrodes, including conductivity electrode, pH electrode and calcium electrode, etc.
Implementation suggestions
- Instrument selection: Prioritize the selection of a multifunctional automatic potentiometric titrator that meets the requirements of GB/T, ensuring that it has dynamic titration and preset endpoint functions.
- Reagent management: Prepare buffer solutions and standard titrants strictly in accordance with standards, and calibrate regularly to ensure measurement accuracy.
- Sample processing: For highly interfering ions (such as copper and manganese), it is recommended to add a masking agent before determination.
