摘要

•A novel QE-IP-QEPAS-based sensor platform cleverly combines AmR and in-plane QEPAS.•A simplified numerical model was utilized to optimize the AmR length, pipe thickness, and inner diameter.•This method of optimizing AmR dimensions was verified through a series of experiments.•An economical and convenient QE-IP-QEPAS spectrophone with a final volume of 2.64 cm3.
