Typical results are shown as metal has the highest corrosion rate but on the addition of the inhibitor the rate drops to the lowest. The test should be repeated at least three times and the results compared for scatter. The percentage protection of an inhibitor is usually quoted this is defined as 100*(uninhibited rate-inhibited rate)/uninhibited rate. The bubble test software will display this for all channels under test. The temperature of the test is important as a whole set of percentage protection values is displayed with respect to temperature.
Bubble Test facilitates running tests in multiples; tests are set up using a simple Bubble Wizard, a series of LPR tests are collected over time giving Corrosion Rate results. Results can be printed at the end in many ways including tables, lines and bar graphs. Cells (or Channels) are assigned together into Groups, each group has an Add Inhibitor button, once pressed, end corrosion rates can be calculated at the end of the test over 3 periods – prior to Add Inhibitor, after 2 hours and after 16 hours, this enables Percentage Protection to be calculated.
