Bubble Test - LPR - Inhibitors Gill 6,8,12 ACM Instruments Kulim Kht

Testing of these chemicals is performed by makers and users. Makers set up initial screening to not reject any potential good ones. Users set up initial screening to reject any potential bad ones. Test metal should be the same metal as that to be protected as should be the test fluid. The two most widely used tests are LPR and Tafel plots. Both are ideally performed using a Gill 8 or Gill 12. The use of a multiple channel instrument allows for replication to gain confidence in the results. The Bubble Test software automatically groups the tests and prints inhibition reports using the LPR method. After all the small LPR perturbations have been made an optional Tafel sweep is performed to obtain the Tafel slopes. AC impedance is less commonly used except with high resistance electrolytes where the IR drop in the solution needs to be measured and overcome.
