Description

Solid-phase extraction post rack

Technical Field

The utility model belongs to pesticide residue detection area relates to the solid-phase extraction technique, especially a solid-phase extraction post rack.

Background

The pesticide residue is a generic term for a pesticide parent, derivative, metabolite, degradation product and impurity remaining in the environment, organism and food after the pesticide is used. The solid phase extraction equipment is the most common detection and purification means in the pesticide residue detection process. Solid Phase Extraction (SPE) is a sample pretreatment technology developed from the mid-eighties, is developed by combining liquid-Solid Extraction and liquid chromatography, is mainly used for separating, purifying and enriching samples, and mainly aims at reducing sample matrix interference and improving detection sensitivity.

The solid phase extraction technology mainly separates a component to be detected from an interference component by depending on acting force between a bonding functional group on a solid adsorbent and a target analyte, and realizes separation and enrichment of a sample. The extraction process is highly dependent on the extraction equipment. The solid phase extraction equipment mainly comprises a filtering device, an extraction column, a vacuum pump and the like. Usually, the sample is poured into an extraction column, and the sample is made to pass through the extraction column by means of vacuumizing or centrifugation, so that the target substance in the sample is adsorbed on the filler of the solid phase extraction column, thereby achieving the separation and purification effects.

The solid phase extraction equipment in the prior art has certain use defects:

1. due to the requirements of detection tests, different types and specifications of extraction columns are required for different tests, and the existing extraction column placing rack cannot meet the requirements of using and storing multiple types and specifications of extraction columns;

2. the adsorption material in the extraction column has high requirements on the environment and the storage equipment because the adsorption material has high requirements on the environment and the price.

Through a search of prior published patent documents, no prior art similar to the present invention was found.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's weak point, provide a simple structure, it is convenient to use, is applicable to multiple specification and dimension's solid-phase extraction post rack with adjustable distance.

The utility model provides a its technical problem take following technical scheme to realize:

the utility model provides a solid phase extraction post rack, includes extension board and adjustable support, two the extension board symmetry set up, adjustable support slide and to dismantle the setting between two extension boards, adjustable support include branch and can dismantle the column plate, be provided with the spout on the extension board, branch slidable mounting in the spout the cover is equipped with the loop bar on branch, an organic whole is made on this loop bar and is installed the piece, has seted up the slot on this installation piece, can dismantle column plate cartridge in this slot.

And the two ends of the supporting rod penetrate through the rod body part of the supporting plate and are provided with external threads, and the two ends of the supporting rod are respectively sleeved with a screw buckle through coaxial threads.

And between the screw buckle and the support plate, a limit plate is sleeved on the support rod through a thread.

Moreover, the detachable column plate is detachably combined into a standard plate and a customized plate, and can be assembled and installed according to actual use requirements and used independently or in combination.

Moreover, at least two adjusting brackets are arranged.

The utility model has the advantages that:

1. this rack is provided with adjustable support, and adjustable support can realize the regulation of height, according to the specification height-adjusting distance of extraction post, can satisfy the requirement and the experimental demand of depositing of the extraction post of multiple specification.

2. This rack is provided with can dismantle the column plate, can dismantle the combination that the column plate can dismantle and set up to standard board and customization board, carries out the aggregate erection according to the in-service use needs, but exclusive use or combination use.

3. The branch of this rack passes through the spiral shell and detains and realize spacing fixed function with the limiting plate, ensures the firm and stability of device, and conveniently adjusts the operation.
