Latest Patents

Liao's latest patents include innovative devices and methods that enhance the detection of weak acids in ion chromatography systems. One of his patents, titled "Permeative amine or acid introduction for very weak acid detection in ion chromatography," describes a permeative amine/acid introduction device (PAID) that is integrated into a conventional KOH eluent suppressed conductometric anion chromatography (SCAC) system. This device converts suppressed eluites from the acid form to the corresponding salt, allowing for the measurement of very weak acids that are typically undetectable by SCAC. The PAID operates without pumps, ensuring dilutionless introduction and effective mixing with minimal band dispersion. An exemplary amine used in this process is diethylamine (DEA), chosen for its favorable properties.

Another patent, "Ion chromatography system and methods utilizing a weak acid or weak base extraction device," further elaborates on the PAID's functionality and its application in ion chromatography. This innovation continues to push the boundaries of what is possible in chemical analysis.
