Abstract: The present disclosure relates to a light energy collecting system and a detection apparatus. Some embodiments of the present disclosure provide a light energy collecting system and a detection apparatus, to correct chromatic aberration, simplify system structure, and improve system reliability and stability.

Abstract: 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.

Abstract: 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.

Abstract: The present disclosure relates to a device for mounting an optical element and a sample processing instrument including the device for mounting an optical element. The device for mounting the optical element includes: a frame; a mount fitted in the frame in a translatable but non-rotatable manner and having a mounting portion for accommodating the optical element; and an adjusting nut attached to the frame in a rotatable but non-translatable manner. The adjusting nut has a screw and a head located at an end of the screw for operation, and the mount has a threaded portion engaged threadedly with the screw, such that when the adjusting nut rotates, the mount translates relative to the frame. The device and the sample processing instrument according to the disclosure can allow adjustment of an optical element while preventing the latter from being off-center.
