Does Hoppy's explanation help?jerrybforl;76183 said:What does all of this mean lol??? Could someone please explain it to me in dumby terms...hehehe
Calibrating a test kit means using that kit to measure some water samples with known concentrations of the substance being tested for, and using those test results to verify that the test kit is accurate, or to train yourself to recognize the colors that correspond to the concentrations you want to test for.
No need for chemistry. You are just matching colors. Have you ever used an aquarium test kit? If you have, then follow the directions above.jerrybforl;76220 said:Not really lol....sorry I should've paid more attention in chemistry class lol!!!

Then the reference solutions are made using "pure" compounds and "pure" water. These give you various color references. Then you compare your sample's color to the reference's color to get an idea of your sample's concentration. It is better to do more than one sample. Do 2 or 3 samples to make sure that the samples are made correctly. If your samples turn out to be different colors, you know that there is an error somewhere. Then you need to find out what is wrong. If all 2 or 3 samples are the same color, you know that either they are made correctly or you made the same, exact error each time.
Hi with this technic,
If I want to make bigger quantity at once,
Can I add 1 or 2 zeros everywhere?
Add 2 mL of the 1000 ppm solution to 18 mL of DI/RO water. This makes 20 mL of a 100 ppm NO3 solution.
Add 20 mL of the 1000 ppm solution to 180 mL of DI/RO water. This makes 200 mL of a 100 ppm NO3 solution.
