Description

Disposable sample collection device and sample collection system including the same {DISPOSABLE GAS COLLECTION DEVICE AND GAS COLLECTION SYSTEM INCLUDING THE SAME}

The present invention relates to a replaceable disposable sampling device and a sampling system equipped with the sampling device.

In order to measure air pollution, a separate sampling device and sampling method are used according to the type of pollutants present in the air. Pollutants can be classified into particulate matter, gaseous matter (volatile matter), semi-volatile matter, and liquid matter. For example, the particulate matter may refer to heavy metals, dust, dioxins, PAHS, and the like, and may be collected using a highball air sampler or a dust sampler device. For example, the gaseous material may refer to VOCs, SO2, NO2, NH3, etc., and may be collected using an infinger (absorption liquid method) or a VOC (tube) sampler device. For example, semi-volatile substances may refer to dioxin, PAHS, and the like, and may be collected using a PUF sampler device. The liquid material may refer to acid rain, and may be collected using an acid rain collector.

Here, to explain the collection of gaseous substances using the infinger, the gaseous substances present in the air are collected by flowing the air through the absorbing fluid in the infinger so that the absorbing fluid in the infinger absorbs the gaseous substances present in the air. . Here, since the collected fluid absorbed in the infinger must be submitted to the inspection agency, the fluid absorbed in the infinger has to be transferred to the test tube, and in this process, the absorbed fluid is contaminated.

In addition, although the sampling policy requires sampling over several days, existing equipment only proceeds on a daily basis, so in the past, workers go to the place where the equipment is installed every day and empty the collected absorption liquid from the infinger , had to reinstall.

In the accompanying drawings, in order to more clearly express the technical idea of the present invention, components that are not related to or detached from the technical idea of the present invention are briefly expressed or omitted.

In the above, the configuration and characteristics of the present invention have been described based on the embodiments according to the present invention, but the present invention is not limited thereto, and various changes or modifications can be made within the spirit and scope of the present invention. It is apparent to those skilled in the art, and therefore such changes or modifications are intended to fall within the scope of the appended claims.
