    Abstract: An LC adapter provided with a built-in light shielding plate includes a frame. One end of the frame is provided with interfaces for matching with connection members. An upper light shielding plate and a lower light shielding plate in a spliced connection with each other are disposed at a position within the frame close to the interfaces. Both the upper light shielding plate and the lower light shielding plate are hingedly connected to the frame through a return spring. When a connection member is inserted into an interface, the upper light shielding plate and the lower light shielding plate rotate relative to the frame and are separated from each other. When the connection member is unplugged from the interface, the upper light shielding plate and the lower light shielding plate are restored to the state of the spliced connection with each other.

  • Patent number: 10260662
    Abstract: Described is a fitting for coupling fluidic paths which facilitates secure and low leak rate fluid flow through a fluidic path junction such as a junction in a liquid chromatography system or other chemical analysis instrument. Fluid containing various mixtures of chemical samples can pass through the junction at high pressure with little or no trapped residue remaining in a volume at the connection. According to various embodiments, a face seal is achieved between two separate fluidic path features. In some embodiments, the sealing of the fluidic paths is aided by the use of a compliant polymer seal. The seal facilitates intimate contact between adjacent surfaces and significantly limits or prevents the entry of fluid under high pressure into an unswept volume. Thus the risk of carryover and its adverse effect on measurements is reduced or eliminated.
