Cou-Lo Formula A & C reagents have been very well received over several years and helped to develop the concept of having both anode and cathode reagents available in the same shipping carton. Over recent years GR Scientific (UK) have been made aware of the industry requirement for different types of coulometric reagents, especially the anode reagent, for specific applications. They are therefore now pleased to launch their new Aquamax KF Reagents which are described as follows:-

Aquamax KF Reagent Frit 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 Cathode this formulation is supplied in a pack of 8 x 100ml bottles, a 50ml bottle of cathode reagent and a plastic funnel for ease of pouring, all conveniently located in a single carton.

For those applications that require a fritless generator electrode, the Aquamax KF Reagent Combi has been developed. This lower cost easy to use anolyte does not require a cathode reagent and is supplied in pack of 8 x 100ml bottles complete with plastic funnel.

To conform to ASTM, API, EI, ISO (plus others) methodology for water content determination of oil and petroleum products, the anode regent must be modified with xylene to improve sample solubility and miscibility. Aquamax KF Reagent Oil is pre-cut with xylene, and other solubilisers to eliminate side reactions, so that the operator does not have to store or mix chemicals. Supplied in packs of 8 x 100ml bottles, a 50ml bottle of cathode reagent and a plastic funnel all conveniently located in a single carton.

GR Scientific 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 they found Aquamax KF Frit and Aquamax KF Combi to be equivalent in perfomance accuracy to the other brands but much faster in titration speed and with low background  drift value. Aquamax KF Oil, specially formulated for oil and petroleum industry samples, 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%.
