The specialty pigment in the CarSecure stickers can be checked using a special hand-held spectroscope, which employs optical and acoustical signals to indicate whether the sticker is genuine.
Furthermore, the plasma optical emission spectra (OES) of the ionization of the working gases were analyzed in situ using a PR-650 spectroscope.
此外,本文使用PR—650光谱光度计,对P室的等离子体辉光光谱(OES)进行了在线监测。
