LogicOil’s Aquamax titrator has been specifically designed for the
determination of water content, combining coulometry with the
Karl Fischer method.
In-lab PPM Water Determination
The LogicOil Aquamax is a truly versatile coulometric Karl Fischer Titrator featuring a robust measuring vessel design with ‘pressgo’ key pad ease.
The LogicOil Aquamax is used to determine trace level water content in a liquid sample and is suitable for a wide range of applications with sample dosing directly into the measuring cell.
Easy to use and simple to programme, the LogicOil Aquamax provides fully automated titration at the push of a button.
The LogicOil Aquamax titrator conformd to the following standards for water determination:
|DIN 51777||ASTM D 4377||IP 471|
|ASTM D 1364||ASTM E 203||ISO 10336|
|ASTM D 1533||IP 356||ISO 6296|
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
LogicOil Aquamax 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 ReagentC 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. LogicOil Aquamax 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.
Extensive comparison trials of LogicOil Aquamax Reagents have been conducted 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, the LogicOil Aquamax A and C were found to be equivalent in performance accuracy to the other brands but much faster in titration speed and with lower background drift values. LogicOil Aquamax 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 %.
