More Information
Summary:The invention relates to a liquid UV on-line detecting automatic analysis recorder, arranging UV light source, calibration tank and hollow cylinder in order on vertical light path from the top down, where at the bottom of the cylinder is a quartz isosceles right-angle triple prism, and a quartz plate is close the bottom, and the cylinder wall between the quartz plate and the triple prism are made with several small holes which make measured liquid able to freely pass through; the inclined side of the triple prism is parallel to the quartz plate and two right-angle sides of the triple prism are coated with total reflection film; the lower part of the calibration tank is provided with the other same triple prism and the upper part of the calibration tank is a hollow quartz tank; on the horizontal light path, reflector, light splitter and detector are in turn arranged from left to right. And the invention can eliminate drift and stray light and has highly accurate detection result.
