Water check
The µg check button on the front panel allows the operator to simply press one button before injecting the 1 µL or 10 µL distilled water as required by the ASTM methods for these analyses. This overrides the programmed calculation settings for a single run so that the display and print out report the result in micrograms water. After running the 10,000 microgram check the coulometer reverts back to ordinary user mode.
Single shot Karl Fischer Reagent
Aquamax KF Reagent A is a general coulometric KF anolyte for use with generator electrodes which incorporate a frit or diaphragm to separate the anode and cathode chambers. Used in conjunction with Reagent C this formulation is supplied in a pack of 8 x 100 mL bottles, 8 x 5 mL cathode vials, all conveniently located in a single carton. To conform to ASTM, API, EI, ISO (plus others) methodology for water content determination of oil and petroleum products, the anode reagent must be modified with xylene to improve sample solubility and miscibility. Aquamax KF Reagent is pre-mixed with xylene, and other solubilizers to eliminate side reactions, so that the operator does not have to store or mix chemicals. We conducted extensive comparison trials of Aquamax KF Reagents against other leading brands with very positive results. Using water standards ranging from 10 µg water up to 10,000 µg water under controlled conditions we found Aquamax KF A and KF C to be equivalent in performance accuracy to the other brands but much faster in titration speed and with lower background drift values. Aquamax KF Reagents, performed much faster than other special oil reagents and at the 10,000 µg count level (as required by ASTM methods), gave a result of 10,004 µg which is within 0.04 %.
