<P>PROBLEM TO BE SOLVED: To provide an automatic analyzer which is capable of suppressing the influence of a phenomenon caused by mixture of gas and liquid in a flow path, on pressure transmission from a syringe to a nozzle. <P>SOLUTION: The automatic analyzer includes: a nozzle 17 for sucking/discharging a liquid or gas; a syringe 32 for generating pressure which makes the nozzle 17 suck/discharge the liquid or gas; a drain 39 for ejecting an object; a flow path comprising a first flow path 20 for connecting the nozzle 17 and a branch portion 23, a second flow path 21 for connecting the drain 39 and the branch portion 23, and a third flow path 22 for connecting the syringe 32 and the branch portion 23; a first on-off valve 30 for opening/closing the first flow path; a second on-off valve 31 for opening/closing the second flow path; and a gas-liquid separating mechanism 33 which is provided at the portion of the second flow path 21 which is on the drain 39 side of the second on-off valve 31, and makes a mixture of gas and liquid to be sent to the drain 39 pass therethrough to separately remove the gas. <P>COPYRIGHT: (C)2012,JPO&INPIT |
