<p>A method of collecting and concentrating a specimen capable of holding measured substances in the pin holes of a porous body inside a column and concentrating the substances by allowing a measured substance-containing specimen to be passed through the pin holes by using the column having the porous body of open structure formed inside a fine tube trough the full diameter and proper length of the fine tube so that pre-treatments forthe adjustment of the specimen such as extraction and concentration of objective components can be performed very easily in short time in a chromatography analysis, comprising the steps of performing the said process as a micro trap in the pre-treatment of the chromatography analysis and leading the process to an analysis means, leading a specimen band to a separation column after reducing the width thereof when leading the specimen into a liquid chromatography, and collecting atmospheric substances such as gaseous substances contained in the air into a collecting tube by using the collecting tube not using a power such as a motor, having a very simple structure as a so-called passive sampler, capable of being produced at a low cost, and capable of uniformly collecting samples by simultaneously usign a large number of tubes to increase the number of measurements, and forming therein, as collecting agent, the porous body of open structure having less ventilating pressure loss and less resistance by adsorbent because if increased surface area, and formed of inorganic, organic, or hybrid polymer partly or wholly in the raw tube thereof.</p> |
