NOTE: When the titration key is pushed, the stirrer bar should begin rotating. Approximately 5 seconds later, electrolysis current will flow which can be viewed in the Bar Graph display screen. As moisture is removed from system, bar graph diminishes to zero and analyzer is ready for measurement. 4Once all moisture present has been titrated out, an audible tone will signal. 5Press “RESET” button to acknowledge signal. 6Ensure current flow is stable on bar graph. 7Shake sample vigorously to homogenize. 8Withdraw and discard to waste at least 3 aliquots of sample. 9Immediately withdraw an aliquot of sample greater than 1 ml. 10Clean needle with a paper tissue. 11Insert needle through the inlet port septum ensuring needle does not come into contact with reagent.

Determination of Moisture in Petroleum Distillates by Karl Fischer Titration Continued 12Press “RESET” key and immediately lower needle with tip of needle just below liquid surface. 13Inject sample slowly ensuring that no splashing occurs. 14Withdraw needle quickly to minimize moisture from air from entering titration vessel. 15When analysis is complete, an audible tone will sound – press “RESET” to acknoledge. NOTE: When analysis is complete an “E” will appear on display screen indicating the final result has been generated. 16Record result to nearest whole number.
