Page 3: Introduction
Designed primarily for the oil and power industries, the Aquamax KF Portable is the only model on the market with a carry handle attached directly to the unit. It also features a protective stainless steel cage, built-in printer and single button operation for water standards analysis, using either distilled water or water pellets. -
Page 4: Principle Of Measurement
Aquamax KF Portable v.13.08 PRINCIPLE OF MEASUREMENT Karl Fischer titration is simply a means to measure water content of samples. Modern instruments, such as the Aquamax KF, use the coulometric principle, whereby the water present in the sample is coulometrically titrated to a predefined end point at which there is a minute excess of free iodine present. -

Page 16: Programming A Method
Aquamax KF Portable v.13.08 PROGRAMMING A METHOD After the initial drift has been calculated, in micrograms (µg) of water per minute, the Aquamax KF Portable is ready for operation. It is now possible to step through the PROGRAM parameters and enter the required calculation data. - Page 17 Aquamax KF Portable v.13.08 CALCULATION MODE The Aquamax KF Portable has four standard calculation modes in memory. Each of these allow the instrument to divide the microgram count by the gram weight of sample introduced so that the calculated result can be printed out in either ppm or percentage of water.
- Page 18 PRINT DRIFT The Aquamax KF Portable can be programmed to print out the drift value for each titration. This is a useful indicator of titration cell stability. If drift is above 25 μg / minute print will show **XX**. This is a...
- Page 19 Aquamax KF Portable v.13.08 DELAY TIMES The Aquamax KF Portable has been programmed to accept two different types of delay times, one at the start of titration and one at the end as a minimum titration time. START DELAY TIME The Aquamax KF Portables has a preset delay of five seconds which allows samples to be dispersed into the reagents before the titration starts.
- Page 20 Aquamax KF Portable v.13.08 LANGUAGE The Aquamax KF Portable can be programmed to show all display prompts and print outs in various • languages. Use the decimal point key to select language then press ENTER. GENERATOR ELECTRODE The Aquamax KF Portable can be operated using generator electrodes with or without frit (diaphragm).

Page 21: Water Standard Test
In Water Standard Test mode the Aquamax KF Portable will display only microgram counts and print out the final result in micrograms. This is an absolute result to check that the titrator is performing correctly and within required parameters. - Page 22 Aquamax KF Portable v.13.08 EXAMPLE COULOMETRIC METHODS The Aquamax KF series of Coulometric Karl Fischer titrators can be used for the following standard methods, either by direct sample introduction or in conjunction with accessories such as water evaporators:- ASTM D 1533...

Page 23: Example Methods & Applications
Aquamax KF Portable v.13.08 EXAMPLE APPLICATIONS LIQUID SAMPLES Liquid samples are usually introduced into the titration vessel by using a syringe. The greater the amount of water introduced into the titration cell will cause the titration to take longer and also consume the reagents more quickly. - Page 24 Some lubricating oils contain additives which can coat the detector electrode or block the glass frit of the generator electrode. For these applications we suggest using the Aquamax KF Portable in conjunction with an oil evaporator such as the model 51000.

Page 31: Troubleshooting
Aquamax KF Portable v.13.08 TROUBLESHOOTING OVERTITRATION Detector senses too much Iodine. Usually caused by old reagents or stirrer switched off. Check stirrer speed. Add 3-5 microlitres of water until detector bars activate, and allow to precondition. EXCESS DRIFT Indicates excess moisture ingress or condensation on cell walls. Switch OFF. Remove titration cell from clamp and gently swirl anode reagent around the cell walls. -
