Bad Automobile Air Conditioner Odors Sampled for GC Analysis
A research group from Kangwon National University (South Korea) set up a laboratory-scale test cooling bench with an airflow, temperature, and relative humidity controller and used it to simulate the unpleasant odor produced by an automobile air conditioner evaporator.
A research group from Kangwon National University (South Korea) set up a laboratory-scale test cooling bench with an airflow, temperature, and relative humidity controller and used it to simulate the unpleasant odor produced by an automobile air conditioner evaporator. The odors were collected in aluminum polyester bags and were analyzed by thermal desorption in a cryotrap followed by gas chromatographic analysis, olfactometry, flame ionization detection, and atomic emission detection and mass spectrometry. Compounds including alcohols, aldehydes, and organic acids were identified as odor-causing compounds.
Dispersive Liquid-Liquid Microextraction: A Review and Roundup of Green Sample Prep Advancements
May 15th 2024The still relatively new technique has distinct advantages, but a few of those benefits make it incompatible with some of the currently accepted principles of green sample preparation.
