    Benefits of radiello ® Passive Sampling Devices

     Most commercially available passive/diffusive sampling devices are planar or axial in shape and offer lower sampling rates and limited sampling capacity. As a result, sensitivity can suffer during short-term analysis (due to low sampling rates), or long-term sampling (analyte back diffusion to low capacity). The radiello system uses a cylindrical outer surface that acts as diffusive ...

    Molded Thermogreen LB-2 Septa

    Injection port septa used in gas chromatographic analyses should exhibit low bleed, resist leaks, and be easy to penetrate. For years, Thermogreen LB-2 septa have been considered by many as the benchmark GC septa for these parameters due to several performance advantages over other commercially available septa. A new generation septum, molded Thermogreen LB-2, continues the Supelco tradition of ...

    Radiello® Manual (PDF 1766 KB)

    In pumped sampling the adsorbed compound behaves as a chromatographic peak (top): air flow displaces it along the adsorbent bed and its concentration is distributed as a gaussian function. Eventually, the compound comes out from the opposite end. When its concentration in the outlet air is 10% of the concentration in the sampled air we say that the breakthrough has been reached or, with a ...
