  • Page 17: Unheated Gas Sampling System

    1.6 Unheated gas sampling system The ecom-ST can be equipped with a so-called NO tubing. The NO tubing effectively minimizes the washout losses of water-soluble gas components like NO and SO . Thanks to its smooth surface and the increased flow rate, the condensation formation and the correlated washout impact are minimized.
