Title:
ANTI-INTERFERENCE WATER QUALITY ANALYSIS INSTRUMENT TEST METHOD
Document Type and Number:
WIPO Patent Application WO/2024/046369
Kind Code:
A1
Abstract:
An anti-interference water quality analysis instrument test method and system. The method comprises: blank calibration: recording a first measurement ADC value after color development (S101); first standard solution calibration: recording a second measurement ADC value after color development (S102); second standard solution calibration: recording a third measurement ADC value after color development (S103); anti-interference factor value measurement: adding an actual water sample according to a predetermined liquid-adding parameter, adding a first reagent for digestion, then recording a fourth measurement ADC value, adding distilled water having the same volume as a second reagent and a third reagent, recording a fifth measurement ADC value after color development, and according to the fourth measurement ADC value and the fifth measurement ADC value, obtaining an anti-interference factor value (S104); and actual water sample measurement: recording a seventh measurement ADC value after color development, and obtaining an actual measurement signal value after anti-interference processing (S105). In the provided anti-interference water quality analysis instrument test method and system, by means of the anti-interference factor value measurement, the actual measurement signal value after anti-interference processing is obtained when the actual water sample is measured, thereby improving testing accuracy.
