Depending on the type of water body and the requirements regarding water quality, there are dozens of water quality parameters that need to be measured. The most widely used instrument in the field of water quality testing is undoubtedly the visible spectrophotometer. Bromine Br, iodine, phosphorus P, calcium Ca, alkalinity, residual chlorine, total chlorine, ammonia nitrogen, total phosphorus P, pH, hardness, chemical oxygen demand COD, and so on can all be measured using a visible spectrophotometer. Today, spectrophotometers with built-in measurement programs are commonly used; these instruments allow for the customization of measurement methods. For standard parameters, the programs can be used directly for measurement, while for non-standard parameters, users can create their own programs to carry out the measurements as needed. Optional pre-made reagents and cuvettes of corresponding sizes are available, making the operation very simple and fast.
What on earth are you discussing here? What are the topics and arguments you are discussing?
I wasn’t clear enough about the points for discussion. Since multiple parameters of water quality need to be measured, electrode-based multi-parameter water quality analyzers are generally used as they are simple to operate. I think spectrophotometers are widely used these days; therefore, I would like to briefly share my understanding of the advantages of spectrophotometers. I’d appreciate hearing everyone’s opinions on this matter, in order to identify any potential improvements for our future multi-parameter water quality monitoring efforts.
