IMMOBILIZED ENZYME COLUMN

摘要

An immobilized enzyme column is used in a chemical auto-analyzer for analyzing materials contained therein, for example, blood serum or urine utilizing an enzyme in clinical tests, and comprises one, two or more columns (19, 34 or 44, 51 and 52). The immobilized enzyme column has a passageway (31) extending from sample-feeding inlet (24) to sample-discharging outlet (27). Bubble-feeding inlet (28) is provided on the sample-discharging outlet side and is connected to the passageway (31), whereas bubble-withdrawing opening (25) is provided on the sample-feeding inlet side and is connected to the passageway. Immobilized enzyme container (20 or 35) partitioned by filters (29) on both ends thereof is provided in the passageway between bubble-feeding inlet (28) and bubble-withdrawing opening (25).
