Problems solved by technology

However, under the existing technology, the above-mentioned steps are mostly completed manually, which makes the labor cost high, and if a large number of samples need to be processed at one time, the labor will be doubled; although some automatic methods for some pre-processing steps have appeared. Equipment, such as oscillators, extraction tubes, etc., can automate some steps in pretreatment, but there is still a lack of equipment that can fully automate all pretreatment processes, which still cannot meet the needs of large-scale sample pretreatment

Embodiment 1

[0061] Figure 1a Shows the sample pretreatment device of the present invention, which can be used for pesticide residues in fruits and vegetables and economic crops

[0062] stay analysis, which includes:

[0063] Sample container conveying assembly 100, it is used for the individual container that holds sample or in height direction

[0064] A stack of containers stacked on top (such as 2-4 containers stacked sequentially in the height direction) is transported to the first predetermined position S1; in this embodiment, the sample can be a plant sample that has been divided or pulverized , such as plant samples such as fruits, vegetables, flowers, and commercial crop samples such as rice, wheat, and tea (including fragments or homogeneous products produced after crushing); the container is cup-shaped, specifically, as Figure 1b-1c As shown, the container includes a main body 20, a first stepped portion 21 extending along the outer wall of the main body 20, and a second ste...

Embodiment 2

[0112] This embodiment also provides a method for performing sample pretreatment by the above-mentioned sample pretreatment device, which includes the following steps:

[0113] S1. Place several containers containing samples in sequence on the sample container conveying component, and transport a single container or a stack of containers to a first predetermined position through the sample container conveying component;

[0114] S2. The container grabbing component grabs a single container or a stack of containers located at the first predetermined position, and separates the single container from the stack of containers, and separates from the single container after moving to the second predetermined position;

[0115] S3. The container receiving component receives the separated single container, and transports at least one container to a third predetermined position;

[0116] S4. The oscillating component grabs at least one container, vibrates the at least one container, and...

Abstract

The invention discloses an oscillation device for sample pretreatment. The oscillation device comprises a support, a shaking part and a grabbing assembly, wherein the support is provided with at leastone stand column; the grabbing assembly is separately connected with the support and the shaking part, can move up and down along the support, and grabs single containers containing samples and sample extracts when moving upwards; the shaking part is used for oscillating the grabbed containers. The oscillation device is high in degree of automation, and can realize one-button type treatment of agreat batch of samples so as to greatly improve the pretreatment efficiency.

Description

technical field [0001] The invention relates to sample detection, in particular to an oscillation device, an oscillation method and a pretreatment device for sample pretreatment. [0002] Background technique [0003] In the existing process of analyzing toxic and harmful residues such as pesticides in fruits and vegetables, samples need to be pretreated, such as crushing, adding extraction reagents, shaking, and extracting supernatants. However, under the existing technology, the above-mentioned steps are mostly completed manually, which makes the labor cost high, and if a large batch of samples needs to be processed at one time, the labor will be doubled; although some automatic methods for some pre-processing steps have appeared. Equipment, such as oscillators, extraction tubes, etc., can automate some steps in pretreatment, but there is still a lack of equipment that can fully automate all pretreatment processes, which still cannot meet the needs of large-scale sampl...
