摘要： The present disclosure relates to a nozzle for a sample processor, a carrier of a nozzle for a sample processor, a nozzle assembly for a sample processor, and a sample processor. The nozzle includes a body and an orifice. The body is adapted to be loaded and held in the carrier. The carrier can be slidably inserted into the sample processor in a detachable manner. The orifice is provided in the body and is configured to inject a sample from an injector body in a predetermined mode. An end surface of the body is adapted to abut against an end surface of the injector body along a sample injection direction. The nozzle assembly and the sample processor according to the present disclosure include the above-described nozzle and carrier. With the aid of the carrier, it is not necessary to install the nozzle to the injector body upstream of the nozzle, so that various adjustment operations when reinstalling the nozzle can be omitted, thereby simplifying the process of reinstalling the nozzle.

摘要： The invention relates to a cuvette assembly for a sample processor, a flow cell for a sample processor comprising the cuvette assembly, and a sample processor comprising the cuvette assembly or the flow cell. The cuvette assembly comprises a cuvette body and a reflector. The cuvette body is in the shape of a rectangular parallelepiped and comprises a sample detection channel vertically penetrating the cuvette body. The cuvette body has long sides and short sides in a horizontal section. The reflector has a flat surface attached to a first side surface extending along one of the long sides of the cuvette body and a spherical surface that is opposite to the flat surface and has a truncated lower half. The reflector is positioned so that it is flush with a lower surface of the cuvette body and a center of sphere of the spherical surface falls into the sample detection channel, and the reflector extends along the long side and exceeds the short side.

摘要： The present disclosure relates to a beam measuring device, a sample processor including the beam measuring device, and a method of measuring a beam using the beam measuring device. The beam measuring device includes a detection unit and a light impediment unit. The light impediment unit is located between the detection unit and a light source, and is configured to generate a shadow area on the detection unit by blocking transmission of part of a beam coming from the light source. The detection unit is configured to measure the shadow area, and to determine whether the beam is divergent or inclined with respect to a predetermined optical axis based on the measurement of the shadow area. The beam measuring device may shorten the optical detection channel and ensure the detection accuracy, thereby having a compact structure. In addition, the beam measuring device may measure divergence angle and directionality, respectively.

摘要： The present disclosure relates to a liquid flow charging device for a flow cell and a flow cell comprising the liquid flow charging device. The liquid flow charging device comprises a first electrode and a second electrode. The first electrode is electrically connected to a liquid flow flowing through a flow channel assembly of the flow cell. The second electrode is located at a predetermined position on a radially outer side of the liquid flow and has a cylindrical inner peripheral surface surrounding the liquid flow. The liquid flow charging device has improved charging efficiency, stable charging performance, and enhanced safety.
