Abstract
To determine the total organic carbon content of a flowing liquid in a continuous process, water and oxidizing agents enter lower ports in a continuous column and flow upwardly along a helical path with air gaps as they are mixed. The helical reaction path is formed by a helical glass cylinder between an ultraviolet lamp and outer wall of a continuous glass tube to cause rapid motion of the liquid. An ultraviolet lamp extends downwardly through the center of the column so that the outer confining surface of the helical path is the outer surface of the ultraviolet lamp, causing the liquid to move rapidly in intimate contact with the ultraviolet lamp to receive intense radiation. An air gap permits escape of air and reduces bubble size to reduce plug flow.
