  1. Where can I find additional ion mobility values?.  For the listing of a large range of relative ion mobility values and appropriate reference sources, click on Mobility Tables.
  2. What is the relationship between ion mobility and limiting equivalent conductivity?.  For the principle underlying this relationship and how to calculate relative ion mobilities from conductivity data, see  Ion_mobility & Conductivity
  3. To what extent do ions contribute to liquid junction potentials, particularly if they not fully ionised or are chelated? Do non-electrolytes contribute to such potentials?  What concentration values for ions should be entered into the program?  See Ion Concentrations.
  4. Can liquid junction potential corrections be applied at the beginning of an experimenta priori corrections?  If so, are there any limitations to such corrections and how must they be applied. Click on a priori corrections (PDF).
  5. Download the updated pdf copy of whole issue of AxoBits 39, with the specific article on liquid junction potential corrections from the Axon website.  This has been corrected for the sign errors in the a priori corrections, which appeared in the original printed version and the initial pre-November pdf version.  This article has a lot of information about the principles underlying liquid junction potentials and how the corrections are calculated and applied using the liquid junction potential calculator.  It also includes worked examples.  To download the liquid junction potential article by itself, click on LJP_article_ AxoBits 39.pdfThese were later corrected in the downloadable pdf version of the article and have been available on the Axon website (  http://mdc.custhelp.com/app/answers/detail/a_id/17450/~/axobits-newsletters )
