Abstract
In an ESI sprayer including a pipe connecting jig used to connect an inlet-side pipe and an ESI capillary, a through-hole having an inner diameter corresponding to an outer diameter of the inlet-side pipe at one end and an inner diameter corresponding to an outer diameter of the ESI capillary at another end is formed in an axial direction of a conductive cylindrical body in which at least both ends are plastically deformable, and a gap forming protrusion protruding inward from a circumferential wall of the through-hole is provided in the cylindrical body.
Claims8
An ESI sprayer comprising:
- an inlet-side pipe and an ESI capillary each made of an insulator;
- and
- a pipe connecting jig,
- wherein a through-hole having an inner diameter corresponding to an outer diameter of the inlet-side pipe at one end, and an inner diameter corresponding to an outer diameter of the ESI capillary at another end, is formed in an axial direction of a conductive cylindrical body, wherein a gap forming protrusion protruding inward from a circumferential wall of the through-hole is provided in the cylindrical body, and both ends are plastically deformed.
A method for connecting an inlet-side pipe and an ESI capillary of an ESI sprayer by a pipe connecting jig, wherein a through-hole having an inner diameter corresponding to an outer diameter of the inlet-side pipe at one end, and an inner diameter corresponding to an outer diameter of the ESI capillary at another end, is formed in an axial direction of a conductive cylindrical body, and wherein a gap forming protrusion protruding inward from a circumferential wall of the through-hole is provided in the cylindrical body, the method comprising:
- inserting the inlet-side pipe from the one end so that a leading end of the inlet-side pipe abuts the gap forming protrusion;
- inserting the ESI capillary from the other end so that a leading end of the ESI capillary abuts the gap forming protrusion;
- and
- plastically deforming both ends of the pipe connecting jig.
