The correct concentration of sodium hypophosphite in the working bath should be 30 g/l. Should
replenishment of hypophosphite only be necessary, assume the concentration of sodium
hypophosphite in QEM EN 1088 C is 500 g/l. This correction should be made after analysis and
replenishment to 100% Ni metal using both QEM EN 1088 A and QEM EN 1088 C.
However, if the concentration of sodium hypophosphite exceeded the limit of 100 g/l, then dilution
of the bath solution may be necessary.
