Integrated sample concentrator comprising nitrogen and air generating unit

Abstract

Provided is an integrated sample concentrator comprising a sample concentrating unit for concentrating a sample and a nitrogen and air generation unit provided below the sample concentrating unit. Thesample concentrating unit comprises: a sample concentrating unit housing provided with a glass window allowing the interior to be observed, and a fan for discharging evaporated solvent; a test tube holder for holding a plurality of test tubes; a sliding shelf provided below the test tube holder; a plurality of spray nozzles for spraying nitrogen or air into the test tubes; a spray nozzle holder for fixedly holding the spray nozzles; an elevating unit for vertically moving the spray nozzle holder; and a control unit for controlling the operation of the sample concentrator. The nitrogen and airgeneration unit comprises: a nitrogen and air generation unit housing provided with a front door and a back door, and barrier plates, with open top and bottom, installed downwardly on the left and right inner walls; a nitrogen generation module containing unit provided with a mode-switching switch to switch between a nitrogen mode and a dry air mode, and equipped with a nitrogen generation modulecomprising a nitrogen membrane for separating nitrogen when compressed air is supplied; a storage tank module containing unit provided with a first pressure gauge for indicating the pressure of nitrogen or air stored in the front, having a supply tube connected in the rear surface thereof to supply the sample concentration unit with nitrogen or air, and having a storage tank module installed in the interior thereof to store nitrogen or air; and an air compression module containing unit provided with a power switch on the front surface thereof to control the operation of the nitrogen and air generation unit, and equipped with an air compression module for suctioning in and compressing atmospheric air. Additionally, the nitrogen generation module containing unit, storage tank module containing unit, and air compression module containing unit are coupled to the nitrogen and air generation unit housing, each having rails provided on both side surfaces thereof to allow sliding, and each being provided with a handle on the front surface thereof.

Description

technical field [0001] The present invention relates to a combined sample concentrator including a nitrogen and air generating unit. More specifically, it relates to a combination of a nitrogen and air generator and a sample concentrator, thereby eliminating the need for large equipment costs for large-scale air-conditioning facilities, and reducing the cost of equipment. Inspection and repair are simple, and when placed in a room such as a laboratory, the appearance can be ensured by a small structure. The nitrogen and air purified in the nitrogen and air generator are directly supplied to the sample concentrator, so it is prevented from being supplied to the sample concentrator A combined sample concentrator that includes a nitrogen and air generating unit to solve the problem of sample denaturation caused by unrefined nitrogen or air. Background technique [0002] Generally, dryers (concentrators) are used in the entire drying process of plants, crops, semiconductors, etc...

AI Technical Summary

Problems solved by technology

However, the air forced to circulate by the fan passes through the heater and becomes high-temperature hot air. After drying the sample, it is discharged to the outside through the exhaust port on the upper part of the chamber. The amount of air that flows into and passes through the above-mentioned exhaust port The corresponding air contains moisture, therefore, the thermal management is structurally ineffective

[0003] In order to solve the above-mentioned problems, Korean Patent No. 10-0762370 discloses that the moisture generated during the drying process of the drying object is removed by a dehumidification unit, and the dry air in the state of removing moisture is discharged to the blower, and the heater passes through the blower. After the blown air is heated, it is discharged to the drying object and dried, so that the drying object can be dried efficiently, and the rod-type test tube used in the experiment of drying a small amount of sample In some cases, an additional shelf is required, and even if a shelf is provided, hot air is used to dry the entire space inside the desiccator, so energy efficiency is reduced, and hot air is used to bring oxygen into contact with the sample, resulting in There is a problem that the material may be oxidized, and the air generated by the blower is supplied, so the air in an unrefined state is supplied, which leads to the denaturation of the sample

[0004] In addition, an additional air compressor is connected to an ordinary dryer in the past to supply air, which will result in the cost and waste of space for additional devices such as an air compressor and a storage tank. Inspection and repair are not easy. When it is installed indoors , will interfere with the aesthetic
