OVER TITRATION
Some times the Aquapal can over titrate; this is not normally an indication of a fault, only if it continuously over-titrates. The purpose of this test is to establish if leaving the instrument on for a day and only injecting Hydranal water standards, does the instrument become unstable and keep going into excess drift, so lets go through the test.
1. With a clean cell and new reagent run the APIII for a day occasionally injecting Hydranal water standards, monitor and record the drift.
DO NOT INJECT your sample, the reason for doing this is to see if a component in the electronics is breaking down after the instrument has been turned on for a period of time.
2. If the Aquapal goes into over-titrating just add a Hydranal water standard to bring it out of over-titration. (If the instrument is stable after a day running water standards, this would indicate the instrument and glassware is okay and the problem lies elsewhere.)
3. When did the Problem start:
During a run of test or after charging with new reagent.

HYDRANAL Water Standard Test
● Draw up more than 2ml
● Push out air
● Weigh syringe
● Type weight in
● Inject 1ml into glassware (hit start while injecting)
● Re-weigh
● Run for awhile.. it asks you to enter new weight..
● Enter new weight
● Print out results

MADE IN THE U.S.
The AquaPal III produces iodine at the wire mesh of the generator electrode. When electricity is conducted across the mesh, one mole of the created iodine, consumes one mole of water. One milligram of water is equivalant to 10.71 coloumbs of electricity. The AquaPal measures the electrical current needed to create iodine, and remove the existing water.
Employing a stepped pulse current, the AquaPal III automatically selects titration speed depending on the amount of water present. As the endpoint is reached, the titration rate slows until the detector signal reaches and maintains the original baseline value. This endpoint is a minute excess of free iodine. At that time, the AquaPal III subtracts any background drift, then calculates and prints the water content.
