چکیده
usual MET-EL-S rubber stopper (3.97 and 3.99 mg/litre), as compared to bottles capped with Parafilm (2.32 and 2.26 mg/litre). For the nitric acid wash of the MET-EL-S rubber stopper, a zinc value exceeding 30 mg/litre was found. The contents of a bottle of the MET-EL-S quality-control serum was mixed and left inverted on the rubber stopper for five days, when the zinc value was found to be 6.80 mg/litre. The zinc in METEL-S control serum is likely to be a function not only of the amount of zinc in the serum but also of how long the control serum remains in contact with the rubber cap. Therefore, no true range for zinc can be established for METEL-S quality control serum until zinc contamination from. the rubber stopper is corrected.
