摘要
PURPOSE: A spectroscopic determination of density in a rectification column is provided to simply measure the density in the rectification column by using an IR spectroscope. CONSTITUTION: The density of materials in a rectification column is measured by an IR spectroscope. A sample loop is guided to the outside of the rectification column at a predetermined height. The sample loop is introduced to the rectification column at a predetermined height of an output hole again, so that the difference between heights occurs. An analysis line(bypass line) is branched from the sample loop, and then, is guided to the sample loop again. The analysis line allows liquid to pass through an IR analysis probe tip. The rectification column is operated within the range of reduced pressure. The density is measured by means of an NIR spectroscope.
