METHOD FOR DETECTION OF FORMALDEHYDE IN A SOLUTION

摘要

The present invention relates to a method for detecting formaldehyde in a solution, the method comprising the steps of: injecting formaldehyde in a reactor using a mobile phase organic solution; separating the formaldehyde by passing the solution through a reverse phase column; detecting the separated formaldehyde through a refractive index detector; and analyzing the detected formaldehyde. According to the present invention, formaldehyde in a solution, which is difficult to detect when the molecular weight thereof is low, can be easily detected without a complicated chemical pre-treating process by inducing a differential refractive index detector in liquid chromatography.
