Abstract
An injector includes an injection device and a round turret provided on a front side of the injection device. A sampler is provided with a vial holder and a conveyance arm. The injector has an accessible structure in which a moving path of the conveyance arm of one sampler arranged on the side of the two injectors for accessing the round turret of each of the two injectors is secured regardless of the size of the round turret, when two injectors are arranged so that the back sides of the injection devices face to each other.
Claims8
An automatic sample injection system for a gas chromatography analysis, comprising:
- two injectors;
- and
- a sampler configured to supply a vial containing a sample to each of the two injectors,
- wherein each of the two injectors includes:
- an injection device having a front side and a rear side, the injection device being configured to collect the sample from the vial arranged at a predetermined position on the front side and inject the sample into an injection port of a gas chromatography analysis device;
- and
- a round turret provided on the front side of the injection device, the round turret being provided with a plurality of vial ports for setting vials on the same circumference in a horizontal plane, the round turret being configured to be rotatable such that an arbitrary vial set to the vial port is capable of being arranged at a predetermined position on the circumference of the round turret,
- wherein the sampler includes:
- a vial holder configured to arrange a plurality of vials thereon in a plane, and
- a conveyance arm provided with a gripper for holding the vial at a distal end, the conveyance arm being configured to convey the vial between the round turret of the injector and the vial holder by operating the gripper within and outside an area where the vial holder is provided,
- wherein the two injectors are arranged such that the rear sides of the injection devices face to each other,
- wherein the sampler is arranged on a side of the two injectors, and
- wherein each of the two injectors has an accessible structure in which a moving path of the conveyance arm for accessing each of the round turrets of the two injectors is secured.
