A water quality detection system includes a conveying module, multiple detection test papers, a supply module, a detection module, and a processing unit. The detection test papers are disposed on the conveying module in a continuous arrangement. The conveying module conveys the detection test papers along a conveying path to sequentially pass through a first position and a second position. The supply module supplies liquid to be tested to the detection test papers passing through the first position. The detection module captures a color signal of the detection test papers passing through the second position. The processing unit generates a water quality signal according to the color signal.

The present invention describes a laboratory system for automatically processing at least one sample container containing a biological sample, the laboratory system comprising a housing; laboratory instrument units for executing processing steps on the biological sample; an input station configured to receive the sample container; a transport means for transport of the sample container from the input station to the laboratory instrument units, and further to an output station; a control unit for determining whether the sample and/or the container is in a condition to be processed by the laboratory instrument units; an input-output station providing an interface between the inside and the outside of the housing; and a workbench on the outside of the housing in front of the input-output station for an operator to be in the position to manipulate the sample and/or the container. Furthermore, the use of such a laboratory system as well as a method for processing a biological sample in a sample container by means of such a laboratory system is described.

Described is an interface module for robotic loading and unloading of a liquid chromatography sample manager. The module includes a transfer drawer receiving apparatus having a device track and a drawer drive system configured to transport a transfer drawer along the device track into and out from a sample tray of a sample manager. The transfer drawer receives a sample-vial carrier that holds samples to be analyzed. The module further includes a window apparatus that has a window controllable to be in an open state or a closed state. When in the open state, transport of the transfer drawer through the window into or out from the sample manager permits loading of the sample-vial carrier into the sample tray and unloading of the sample-vial carrier from the sample tray. In the closed state, the window apparatus substantially seals the internal environment of the sample manager from the ambient environment.

The present disclosure relates to the technical field of automated analysis, and provides a sample analysis system and a control method for the same and a sample analysis method. The sample analysis system includes: a control device; a rail device for carrying cuvettes under control of the control device; at least one independent sample distribution node arranged on the rail device for distributing samples to the cuvettes, the independent sample distribution node being used for sample aspiration, transfer, and discharge; and at least two independent reagent distribution and measurement nodes arranged on the rail device for distributing test reagents to the cuvettes and measuring the mixture liquid in the cuvettes, the independent reagent distribution and measurement nodes being used for reagent aspiration, transfer, and discharge and reagent-sample mixture liquid measurement.

A system including an optical signal detector and a controller operatively coupled to the optical signal detector and configured to determine an operational performance status of the optical signal detector. The optical signal detector includes a detection channel having a light source and a sensor, where the detection channel is configured to emit and focus light generated by the light source at a detection zone and to receive and focus light on the sensor. The optical performance status of the optical signal detector is based on a measured characteristic of light focused on the sensor while a non-fluorescent surface is in the detection zone and/or a measured characteristic of light focused on the sensor while a void is in the detection zone.

In a solid phase extraction (SPE) apparatus, a cartridge housing tray houses a plurality of SPE cartridges. A liquid loading assembly applies liquid samples and SPE solutions into the plurality of cartridges. A liquid drawing assembly forces the liquid samples and the SPE solutions once they are applied to pass through the plurality of the SPE cartridges.

A sample rack transport apparatus for transporting a sample rack to a sample analyser, comprising: a bidirectional transmission track for bidirectionally transmitting a sample rack without passing through the sample analyser; a feed channel in parallel with the bidirectional transmission track, wherein the sample rack may be delivered from the bidirectional transmission track to the feed channel and to the sample analyser; an unloading cache region located between the bidirectional transmission track and the feed channel, the unloading cache region being used for storing the sample tack; and an unloading mechanism for delivering the sample rack in the feed channel to the unloading cache region for storage, or delivering the sample rack stored in the unloading cache region to the bidirectional transmission track. Also provided are a sample analysis device and a sample analysis system using the sample rack transport apparatus.

A fully automatic test card conveying apparatus for an instant testing instrument is used for conveying a test card and includes a test card conveying arm, frame, push rod, buffer support, buffer cartridge, and card extraction mechanism.
