The GroLine general purpose cleaning solution can be used for a variety of applications. Cleaning is a fast and effective routine that should be performed on a regular basis as a p reventative measure against using a dirty electrode and to ensure that the junction is not clogged. By simply immersing the electrode in the GroLine cleaning solution for 15 to 20 minutes will dissolve any mineral deposits or other coatings. Electrodes can become dirty from use and produce inaccurate results even if they are read correctly in a pH buffer. Hanna's cleaning solutions eliminate impurities and residues that are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly. Hanna suggests cleaning the bulb and junction of your electrode on a regular basis to ensure that the probe is always clean and to prevent any clogging of the junction. The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note because, during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration. pH meters on the market today will allow an offset voltage of approximately ??60 mV. The deviation from 0 mV is not unusual but ideally should be no greater than ??30 mV. The calibration process compensates for the change in offset voltage. If the mV offset continues to deviate and the meter is calibrated with a dirty electrode then inaccurate readings will result.
