Abstract
Obtaining sufficient suppression effect of channel diffusion and stably transferring solution are made possible even in a piping having an extremely small inner diameter used for an analysis apparatus such as an HPLC. A piping device for an analysis apparatus includes a piping equipped with a folded shape that suppresses inner channel diffusion, and a member directly or indirectly in contact with the piping from at least one side to support the piping to suppress deformation of the folded shape.
Claims20
A piping device for an analysis apparatus comprising:
- a piping including a diffusion suppression part which has a continuously folded shape, wherein the piping has an inner diameter and an outer diameter, the diffusion suppression part has a plurality of folded parts so as to suppress inner channel diffusion, and the diffusion suppression part has a length;
- and
- a member that is provided along the diffusion suppression part and is directly in contact with the whole of the length of the diffusion suppression part to support the diffusion suppression part to suppress deformation of the folded shape.
An analysis apparatus comprising at least:
- an analysis flow channel;
- a sample injection unit that injects a sample in the analysis flow channel;
- a separation unit provided on a downstream side of the sample injection unit on the analysis flow channel, the separation unit being configured to separate the sample injected by the sample injection unit;
- and
- a detector provided on a downstream side of the separation unit on the analysis flow channel, the detector being configured to detect a sample component separated by the separation unit, wherein
- at least a portion of a flow channel on the downstream side of the sample injection unit among a flow channel forming the analysis flow channel is formed of a piping device,
- the piping device comprises:
- a piping including a diffusion suppression part which has a continuously folded shape, wherein the piping has an inner diameter and an outer diameter, the diffusion suppression part has a plurality of folded parts so as to suppress inner channel diffusion, and the diffusion suppression part has a length;
- and
- a member that is provided along the diffusion suppression part and is directly in contact with the whole of the length of the diffusion suppression part to support the diffusion suppression part to suppress deformation of the folded shape.
