Each partition of the detection disc may be equipped with one chip to be detected, and multiple chips can be detected in one operation by using the rotatable detection disc.

A method for measuring optical signal detector performance that includes directing light emitted from an optical signal detector onto a first non-fluorescent surface portion in a first detection zone of the optical signal detector. A first characteristic of light detected by a first sensor of the first optical signal detector is measured while the first non-fluorescent surface portion is in the first detection zone of the optical signal detector. Light emitted from the optical signal detector is directed into a first void in the first detection zone of the optical signal detector. A second characteristic of light detected by the first sensor of the optical signal detector is measured while the first void is in the first detection zone of the optical signal detector. And an operational performance status of the optical signal detector is determined based on at least one of the first characteristic and the second characteristic.

The present invention relates to an autosampler. The autosampler includes a sampling needle, a swing arm, a main shaft, a synchronous rotating pulley, and a rotating shaft sleeve. One end of the swing arm is fixed to the main shaft, and the other end thereof is fixed with the sampling needle for supplying a sample. The rotating shaft sleeve is installed in the synchronous rotating pulley, and the rotating shaft sleeve is mounted on the main shaft. The main shaft can rotate around the central axis of the main shaft in synchronization with the rotating shaft sleeve, and can move up and down in the direction of the central axis with respect to the rotating shaft sleeve. The autosampler is characterized in that it further includes a contact member. The contact member penetrates the synchronous rotating pulley and the rotating shaft sleeve from one side of the synchronous rotating pulley in the radial direction thereof until it comes into contact with the main shaft. The contact member is in rolling contact with the main shaft. According to the present invention, the contact member may provide a radial force to the main shaft so as to eliminate a fitting gap between the main shaft and the rotating shaft sleeve, and may reliably fix the synchronous rotating pulley and the rotating shaft sleeve so as to ensure the accuracy and reproducibility of the injection position.

A sample dilution method. The method comprises the following steps: moving from an initial workstation to a first workstation a ferrying unit bearing a first reactor containing a sample; distributing a diluent into the first reactor located at the first workstation; mixing the diluent and the sample in the first reactor to form a diluted sample; moving to a second workstation the ferrying unit bearing the first reactor containing the diluted sample, and distributing into at least two empty second reactors the diluted sample from the first reactor; moving to the first workstation the ferrying unit bearing all the second reactors containing a diluted sample, and distributing a reagent into the second reactors located at the first workstation; and mixing the reagent and the diluted sample in the second reactor.

Disclosed are high-throughput vessel supply systems and methods of supplying sample vessels, such as samples stored in test tubes. A system for supplying a plurality of individual vessels that each contains a sample is disclosed.

The present disclosure provides a gate system for sample detection and a method of sample inspection, which relate to the field of detection and analysis technology. The gate system comprises: an accommodating apparatus configured to accommodate an inserted ticket to be detected; a wipe sampling apparatus including a wipe sampling belt which is configured to drive the ticket to be detected to move within the accommodating apparatus and to conduct a wipe sampling to the ticket; an inspiratory sampling apparatus configured to collect samples dropped from the wipe sampling apparatus; and a detection apparatus configured to detect the samples and output detection results. The gate system for sample detection and the method of sample inspection provided by the present disclosure have a wide range of applications and can perform rapid sampling and detection to those substances that are difficult to be volatilized.

An automated analyzer includes a container installation portion in which a container, such as a reagent container, has a protrusion and an openable and closable lid. A lid opening and closing mechanism opens and closes the lid and includes an arm portion having an arm and a horizontal driving portion which moves the arm in a first horizontal direction. The arm includes a protrusion contacting portion that includes a first surface having an angle greater than 0 degrees and less than 90 degrees when the horizontal surface is set as 0 degrees. The lid opening and closing mechanism portion opens the lid by moving the arm in the first horizontal direction, contacting the lid protrusion on the first surface of the protrusion contacting portion, and then moving the lid protrusion along a shape of the first surface in a vertical direction, until the lid is opened.
