    Product Features

    With an independent drawer type design


    It can change the sample separately, and can also set the sample measurement time separately according to the sample activity


    Individual stopping of one measurement can be set

    Detectors are independent measurement channels, and the overall gas system is connected in parallel, so each channel works independently without mutual influence.

    The detector can be replaced directly for easy maintenance

    The anti-coincidence detector adopts an air flow proportional counter with a gamma anti-coincidence efficiency of more than 99%

    Data can be transferred to the database

    Count measurement mode or MDA measurement mode can be selected at your need

    Can be extended to up to 10 detectors

      OTCS11/1 Oxidizer for biological samples

      Principle It is designed for secondary high temperature oxidation zones. The oxidative combustion of organic samples in a high-temperature aerobic environment generates water and carbon dioxide. It absorb carbon dioxide through the bulb, and utilizes this principle to extract tritium and carbon-14 from biological samples, thus facilitating the measurement of tritium and carbon-14 activity by liquid scintillation counters.
