Embodiment Construction

[0022] Such as figure 1 and 5 As shown, the large-volume sample loading device disclosed in the present invention includes a sample loading rack 1, a sample loading bottle box 2, a 1L sample loading bottle 3, a sleeve body 4, a joint 5 and a sample loading needle 6;

[0023] The upper end of the sleeve body 4 forms an upper socket 41 for inserting the sample needle 6, and the lower end of the sleeve body 4 opens a lower threaded hole 42 for the joint 5 to be screwed and locked. The connecting hole 43 through which the needle head 61 of the sample loading needle passes, 20 sleeve bodies 4 are installed on the top of the sample rack, and a joint 5 is inserted on each sleeve body 4;

[0024] 20 1L sample bottles 3 are set in the sample bottle box 2 corresponding to the 20-position sleeve bodies, and the 20-position sample bottles 3 are connected to the 20-position sleeve bodies 4 one by one through the joint 5. Specifically, the joint 5 and the 1L sample loading A Teflon thin h...

Abstract

The invention discloses a large-volume sample loading device. The large-volume sample loading device comprises a sample loading frame, a sample loading bottle box, 1L sample loading bottles, sleeve bodies, joints and sample loading needles, wherein upper insertion holes for being inserted by the sample loading needles are formed in the upper ends of the sleeve bodies, lower threaded holes for being screwed and locked by the joints are formed in the lower ends of the sleeve bodies, connecting holes for being penetrated by needle heads of the sample loading needles are formed between the upper insertion holes and the lower threaded holes, 20 sleeve bodies are mounted on the top of the sample loading frame, and one joint is screwed to each sleeve body; 20 sample loading bottles corresponding to 20 sleeve bodies are arranged in the sample loading bottle box and are in one-to-one connection with 20 sleeve bodies through the joints. According to the large-volume sample loading device, the problems of poor sealing property and big errors of a traditional sample loading device are solved, and the sample loading efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of sample loading devices, in particular to a large-volume sample loading device. Background technique [0002] Existing sample loading device mainly comprises 20 sample loading needles, sample loading seat and 20 20ml sample test tubes installed on the sample loading seat, by installing 20 20ml test tubes on the sample loading seat, the sample loading needle extracts the solution, the entire process of the sample loading device can only extract 400ml of sample solution, which is not only inefficient, time-consuming and laborious, but also the sealing between the sample loading needle and the test tube is not good, resulting in large sample loading errors. [0003] In view of this, the inventor improved the sample loading device, and specially developed a large-volume sample loading device that increases the volume of the sample passing through the column, reduces manual operations, saves time and effort, an...
