Organic Passive Sampler
About
In our country, outdoor air quality is required to be determined within the scope of the Regulation on the Control of Industrial Air Pollution and the Regulation on Air Quality Assessment and Management, and for this purpose, imported passive samplers are used in our country. In this study, passive sampler adsorbent material was developed for benzene, toluene, ethylbenzene and xylene (BTEX) parameters, which are organic pollutants that need to be monitored in the outdoor environment, and a passive sampler for organic pollutants was produced.
Product Overview
Passive samplers are increasingly being used throughout the country every year within the scope of preparation of clean air plans, air pollution mapping and/or air quality determination studies. The fact that passive samplers are simple, easily portable and inexpensive, as well as providing the opportunity to sample at multiple points simultaneously without the need for electrical power, makes passive samplers advantageous compared to other sampling methods in regional scale air quality measurements. The sampler developed to determine outdoor air quality is designed to determine the results of organic pollutants. The sampler contains a polymeric adsorbent material that will retain organic pollutants. The sampler prepared in the laboratory is left in the outdoor environment for a certain period of time for the organic pollutants to be held by the adsorbent material and at the end of the time, it is transported to the laboratory and analyzed.

Technical Specifications
It is made of stainless steel material according to the dimensions in Figure. There is a 100 mesh stainless steel filter and trap (Figure 7) that prevents the adsorbent with a particle size of 40-60 mesh from spilling into the tube but allows the diffusion of organic pollutants. A channel cut 15 mm from one end of the steel tube serves as a trap for the filter in the tube. At the other end of the steel tube, which is filled with approximately 200 mg of polymeric adsorbent, a second 100 mesh filter and filter holder is attached to the adsorbent. The adsorbent-filled samplers are conditioned in a thermal desorber at 340 °C and 100 ml/min nitrogen gas for 90 minutes and then stored in a refrigerator at +4 °C until field application, tightly closed with a sealed teflon-lined brass cap on both ends.
