How can the detection of silicon in boiler water show a negative value?

by:BOQU     2023-04-09
When it comes to water quality testing, it is relatively broad, such as medical wastewater, domestic sewage, industrial wastewater and other testing work, and the staff may have large errors in the testing data due to some external factors during the testing process. For the detection of silicon in boiler water, how can I hear that there are negative values? So far, the partners have not heard of this phenomenon, but no matter what, this possibility cannot be ruled out! However, the reason for this situation still needs to be analyzed by technicians after understanding the situation. There may be problems with the instrument, but it may also be a problem with the operation of the staff. The specific reasons need to be analyzed in detail! An instrument that can be used to detect the silicon content in water. This online silicon analyzer in water uses the universal standard molybdenum blue analysis method to continuously monitor the content of silicon or silicate in water. The working principle is: the water sample is filtered and then transferred to the reactor. At this time, the masking agent is injected to remove some interfering substances, and then the pH value of the solution is adjusted to a suitable pH value, and then the characteristic chromogenic agent is added to carry out a color reaction, so as to detect the absorbance of the reactant, through which the absorbance can be Calculate the concentration of silicon in the water. The main application areas are: boiler water, condensate water, electric field non-feed water and boiler water, etc. The silicon online analyzer in water has a self-diagnosis and early warning system. For example, if the water sample is suddenly interrupted, there will be a reminder signal. In addition, each sample analysis will have the effect of automatic zero adjustment, less reagent consumption, and can also ensure the uniformity and stability of reagent quality, and less maintenance.
