Methods for determining the pH value of solutions and discussion on the effects on ion concentrations in solutions
Thread Content
1. Generally, what method should be used for testing in order to obtain a more accurate pH value for the solution? 2. Since I plan to use ICP-MS to measure the concentrations of certain ions in the solution, does the order in which the equipment is used to determine the pH value of the solution matter? Should one first use the device to measure the pH of the solution, and then use ICP for detecting ions in the solution, or should one first use ICP to measure the ion concentration and then use the device to determine the pH? 3. What are the precautions when using a device to measure pH?
1. If the components of the solution remain stable when exposed to air, it can be measured using a pH meter with high precision; such a meter must be preheated and calibrated before use, and its readings remain relatively stable. 2. Mix the solution evenly, pour out a portion to measure the pH value, and use ICP to analyze the ions in the remaining portion.
In other words, if the solution is well mixed, the pH value and ion concentration can be determined by testing the solution in two separate portions, right?

I also want to ask: are PH meters with high precision generally portable? I see there are also PH meters; I wonder what the accuracy of measurement is like?
The high-precision detector we use has three decimal places.
Well, I checked online as well, and it turns out that detectors work better!
