Abstract
An immobilized enzyme column useful for automatic chemical analyzers for analyzing substances contained in the blood serum, urine or the like with use of an enzyme for clinical tests includes at least one column main body (19, 34 or 44, 51 and 52). The column has a channel (31) extending from a sample inlet (24) to a sample outlet (27). An air bubble inlet (28) is disposed close to the sample outlet to communicate with the channel (31), and an air bubble outlet (25) is disposed close to the sample inlet to communicate with the channel. An immobilized enzyme accommodating portion (20 or 35) is provided in the channel between the bubble inlet (28) and the bubble outlet (25) and partitioned by a filter (29) at each end thereof.
