32、eshly whenever needed. NOTE The amount of the aluminium oxide solution to be used is determined by the chemical composition of the sample. For example, use 35 ml for the aluminium oxide solution of a sample containing 35 % by mass of aluminium oxide. 3.2.3 Matrix solution 2 or 2. Carry out the proce
