  • (b) for the first finished lot of Insulin Zinc Suspension-Medium prepared from each master lot of insulin or zinc-insulin crystals,

    • (i) a report on the amount of each component used in the preparation,

    • (ii) a report of assay of its nitrogen content in milligrams per cubic centimetre or per 1,000 International Units of insulin,

    • (iii) a report of assay of its zinc content in milligrams per cubic centimetre or per 1,000 International Units of insulin,

    • (iv) a report of the insulin content, in International Units per cubic centimetre, of the supernatant liquid after removal of the suspended precipitate,

    • (v) a report on the determination of the proportion of the nitrogen in the crystalline component of the suspended precipitate,

    • (vi) a report of assay of the zinc content of the supernatant liquid after removal of the suspended precipitate,

    • (vii) a report on the determination of its pH, and

    • (viii) a report on the microscopic appearance of the suspended precipitate; and

  • (c) for the first filling of the first finished lot of Insulin Zinc Suspension — Medium from each master lot of insulin or zinc-insulin crystals,

    • (i) a report on the determination of its pH,

    • (ii) a report on the microscopic examination of the precipitate, and

    • (iii) a report on its identification as determined by an acceptable method.

    • (iv) [Repealed, SOR/95-203, s. 4]
