Abstract
Provided are an automatic sampling device and method and, more specifically, are an automatic sampling device and method which automatically remove a lid when collecting a sample in order to analyze the state of a chemical solution (medicinal fluid) and which automatically reverse a sample collection container so that the container can be used after being washed with ultrapure water, and thus the device prevents medicinal fluid contamination caused by the sample collection container, lid, adjacent objects in contact therewith, or space during sampling, without being affected by outside conditions during the sampling, prevents safety accidents such as errors or risk caused by manual work, and is improved so as to increase the reliability of sampling.
Claims31
An automatic sampling device comprising:
- a container standby unit (20) for preparing a plurality of containers (BT) before testing, and sequentially rotating the container standby unit (20) to select a container (BT) for extracting a sample;
- a container transfer unit (40) gripping the container (BT) selected by the container standby unit (20), transferring the container to a sampling chamber (300), and automatically inverting the container;
- and
- a lid separation unit (30) automatically opening and closing a lid (CAP) in the sampling chamber (300) from the container (BT) transferred by the container transfer unit (40).
A method for automatically sampling a solution using an automatic sampling device, which comprises a container standby chamber (200), a sampling chamber (300) for cleaning a container (BT) and a lid (CAP) and holding a sample solution, a lower machine room (400) which is located at the opposite side of the container standby chamber (200) and in which a container transfer unit (40) is mounted, and an upper machine room (500) having a driving means for driving a container standby unit (20) and a lid separation unit (30) on an upper portion of the sampling chamber (300), the method comprising the steps of:
- preparing sampling by arranging a container (BT) having a lid (CAP) in a space between rotors (240) of the container standby unit (20) provided in the container standby chamber (200);
- moving the container (BT) to an open position of the lid (CAP) on the sampling chamber (300) after vacuum-adsorbing the container (BT) by advancing the adsorption stand (450) of the container transfer unit (40);
- lowering the lid gripper (310) of the lid separation unit (30) to grip the lid (CAP), separating the lid (CAP) from the container (BT), and lifting the separated lid (CAP);
- moving the adsorption stand (450) backward to move the container (BT), form which the lid (CAP) is separated, to a sampling position, and lowering the lid (CAP);
- rotating an inversion motor (M) of the container transfer unit (40) to invert the container (BT) at 180°, and cleaning the lid (CAP) and the inside of the container (BT) with a solution or ultrapure water;
- and
- standing the inverted container (BT) upright, and injecting a sample solution into the container (BT).
