Description

Multiple Sample Collection Device

The present invention relates to a multiple sample collection device, and more particularly, to a multiple sample collection device that can simultaneously collect a gas or a liquid and a solid sample.

With industrial development, many pollutants are generated and cause various problems as well as human health. In recent years, various test methods have been established and implemented to cope with these problems and analyze pollutants for pollutant regulation.

Sampling process is necessary for the analysis of such pollutants, and the process test method is required to use an appropriate sampling device.

Most of the commercially available collecting devices are classified into gas, liquid and solid collecting devices. However, this is a separate device for collecting general contaminants and must be provided with a separate device such as a pump.

The gas collecting device collects air samples by using an adsorption tube or a container. In particular, the adsorption tube method is limited to be collected according to the adsorbents to be filled, and a separate pump must be used. In addition, commercially available canisters and tedala bags have the advantage of collecting all materials, but various expensive equipment is required for cleaning and preparing preparations.

The solid or liquid collecting device mainly uses the container collecting method and is made of materials such as plastic, Teflon, stainless steel, etc.

All of these sampling devices have been commercialized based on the method used individually in a specific environment and collected at a low concentration level, and thus there is a problem in that a sample cannot be collected except specific environmental conditions.

The present invention is to solve the above problems, it is possible to secure a plurality of samples to be collected at the same time without having a separate equipment in a complex type environment, such as accident / disaster / terrorism, gas or liquid and solid samples It is an object of the present invention to provide a multiple sample collection device that prevents the sample from being agitated with a sample in another chamber or prevents the loss of the sample and external contamination.
