3TheHPDW2000-ANAnalysis process

◇Analysis process

Clean the analysis module multiple times with deionized water using a peristaltic pump to remove the samples and residues left from the previous measurement.

Turn on the peristaltic pump and clean the module with samples to prevent water on the module wall from diluting the sample, which can reduce errors caused by the environment.

Add sample

By using a precise peristaltic pump, buffering agents are accurately added, and reagents are re administered using a high-precision diaphragm pump.

After sufficient reaction and color development

By adding the content of ammonia nitrogen detected through colorimetric conversion
