Polyethyleneimine-Modified Quartz Crystal Microbalance and its Characteristics for Detecting Acetic Acid
Summary
An acetic acid vapour sensor made by depositing a polyethyleneimine layer on QCM crystals through a self-assembled monolayer route. The coated sensor was little affected by humidity and detected acetic acid with high sensitivity and a detection limit of 0.85 mg/L, aimed at protecting people from the irritating vapour.
Summary written by the openQCM team. The original abstract is on the publisher’s page.
