AI Technical Summary

Technical Problem

Existing methods for analyzing taste and odor-causing substances in water, such as 2-MIB and Geosmin, are time-consuming and impractical for real-time monitoring, limiting the ability of water purification plants to respond promptly to changes in water quality.

Method used

A device and method utilizing an ultrasonic vaporization unit to create an aerosol sample, coupled with MS/MS mass spectrometry and a digitization unit, enables real-time measurement of 2-MIB and Geosmin without the need for a column or gas chromatograph, allowing for rapid response to algae growth and quality changes.

Benefits of technology

This approach reduces measurement time, lowers costs by optimizing chemical usage, and enables real-time monitoring and rapid response to odor-causing substances, minimizing water quality deterioration.

Abstract

The apparatus for automatically measuring and monitoring taste and odor-causing substances in water (raw water, purified water, and discharged water) according to an embodiment of the present invention includes: a vaporizing unit which introduces water (raw water, purified water, and discharged water), atomizes the water by using an ultrasonic vibrator, and then sprays the atomized water into a spray chamber, thereby generating an aerosol-type sample; an MS / MS mass spectrometry unit which applies a chemical ionization method using plasma and a quadrupole mass spectrometry (MS / MS) to the aerosol-type sample generated in the vaporization unit to measure mass values of 2-MIB S and Geosmin, which are taste and odor-causing substances; and a quantifying unit which quantifies the mass values of 2-MIB and Geosmin relative to the sample mass, measured by the MS / MS mass spectrometry unit.
