ABSTRACT:
A method for the quantitative determination of micro-organisms or pyrogens which comprises introducing a prescribed amount of a test liquor containing micro-organisms or pyrogens into a total carbon analyzer to obtain a total carbon value A, while removing micro-organisms or pyrogens from the prescribed amount of the same test liquor and introducing the resultant into a total carbon analyzer to obtain a total carbon value B, subtracting the total carbon value B from the total carbon value A and determining micro-organisms or pyrogens basing upon the resulting value, and an apparatus suitable for conducting the method.
