Description

Technical Field

[0001] This utility model relates to the field of chromatography technology, specifically a high-precision liquid chromatograph. Background Technology

[0002] A high-precision liquid chromatograph is a precision instrument that uses the principle of high-performance liquid chromatography to analyze organic compounds that have high boiling points, are not easily volatile, are unstable when heated, and have large molecular weights. It mainly consists of a liquid reservoir, a high-pressure pump, an injector, a chromatographic column, a detector, and a recorder.

[0003] Chinese patent CN211263324U discloses a high-precision liquid chromatograph. This utility model has an anti-collision cotton sleeve installed on the inner side wall of the placement slot, a shock-absorbing pad fixedly installed at the bottom of the placement slot, and an observation slot opened at the center of the corresponding placement slot on the front side wall of the reagent bottle placement rack. This allows for the placement of reagent bottles while protecting them, thus improving stability.

[0004] The aforementioned equipment places reagent bottles in a fixed placement slot during use, with the bottom and sides protected by anti-collision cotton sleeves and shock-absorbing pads. The fixed placement slot, even though the anti-collision cotton sleeves can provide slight deformation, cannot accommodate reagent bottles of different sizes. This results in certain limitations when using reagent bottles of different specifications, reducing the applicability of the instrument, and requires optimization and improvement.

Guide screws 202 are welded to both the front and rear sides of the top of the placement box 201, and fastening nuts 203 are threadedly connected to the outer top of the guide screws 202.

[0038] In this embodiment: the placement box 201 is at the top, where reagent bottles can be placed, and the connection between the guide screw 202 and the fastening nut 203 can fix the position adjustment component 3.

[0039] Specifically, such as Figure 2 As shown, the position adjustment component 3 includes an adjustment plate 301, which is inserted into the inner middle of the placement box 201.
