WTF 6000L Multi Parameter Water Quality Analyzer Analysis methods: spectrophotometry, anodic dissolution method, potentiometric titration method, luminescent bacteria method

Automatic cleaning, automatic calibration, automatic verification

According to the surface water quality standard (GB3838-2002), in some monitoring projects, the monitoring results are below the detection limit and it is confirmed that there are no new sources of pollution. Therefore, the monitoring frequency can be reduced. According to the different economic development situations in various regions, the selected testing items should be monitored once a year in areas with monitoring capabilities (equipped with GC/MS).

Choosing the correct monitoring and analysis method is an important characteristic for obtaining accurate results. The principles that should be followed when selecting analysis methods include: sensitivity and accuracy that meet quantitative requirements; Mature methods; Good anti-interference ability; Easy to operate and easy to popularize. Based on the above principles, in order to ensure comparability of monitoring data, the Organization for Standardization (ISO) and various countries have developed standardized analysis methods for different pollutants in various types of water bodies based on extensive practice. In China, as of the end of June 2005, there were 141 water quality analysis method standards issued by the National Environmental Protection Administration, accounting for about 35% of the total national water environment standards.

There are three levels of water quality monitoring and analysis methods, which complement each other and form a complete monitoring and analysis method system.

（1） China has developed over 140 standard analysis methods, including sampling, for national water quality standards. These are some of the more classic and accurate methods

Conventional analysis and testing methods include chemical analysis and instrumental analysis. Currently, there is a trend towards instrumentation and automation in various monitoring items in water quality monitoring, with commonly used monitoring methods
