Hank Kwok, water analysis and purification specialist with Thermo Scientific, will give a pH seminar on Wednesday, June 29, 2016, at 11:00 am, in the Regis and Joan  Duffy Research Centre, Room 212. Seminar topic will include electrode operation and selection, meter calibration and buffer selection, temperature effects on samples, and troubleshooting common problems. After the seminar, Hank will be available for several pH clinics held in labs around campus where he will look at instrumentation and provide some hands-on testing of equipment and electrodes. Hank has indicated these clinics would be particularly useful to users attempting to measure pH in the areas of Environmental Science and Foods and Nutrition as their samples are typically more challenging. If you are interested in Hank stopping by your lab, please let Stephen Scully (sscully@upei.ca) know.
