Appeal No. 1999-1276 Page 2
Application No. 08/318,574
Claim 1 is illustrative of the claims on appeal and reads as follows:
1. A method for quantitating an organic peracid comprising:
introducing into a sample solution containing an organic peracid in the
presence of a high background of hydrogen peroxide in said solution, an amount of
catalase sufficient to decompose said hydrogen peroxide in said solution;
reacting all of the hydrogen peroxide present in said solution with sufficient
amount of said catalase without decomposing said organic peracid present in the
solution; and
quantitating said organic peracid in ppm active oxygen (A.O.) by measuring
an amount of said organic peracid in an absence of said hydrogen peroxide.
