BID Detector

Advanced Industrial Chemistry (A.I.C.) detectors are based on the use of a dielectric barrier discharge (D.B.D.). A D.B.D. is a plasma discharge that is obtained using a high voltage alternating current applied to a dielectric material like glass or pyrex. The application of high voltage to a gas re...

How to select graphite tube types for the electro-thermal atomization (furnace analysis) method

Selection of graphite tubes to match the element or sample is beneficial to the electro-thermal atomization method (furnace analysis method). Currently there are three types of graphite tube that are widely used - high- density graphite tubes (high-density tubes from here on), pyro-coated graphite tubes (pyro-coated tubes from here on), and platform-type graphite tubes (platform tubes from here on).
