摘要: 基于可见-近红外光谱技术研制了一种便携式硫熏中药材快速检测仪器,主要由锂电池组、DC/DC变换电路、恒流源部分、光源部分、样品池、微型光纤光谱仪、笔记本电脑等组成.阐述了仪器的构成及工作原理,给出了卤钨灯恒流驱动电路原理图,并详细介绍了其工作原理和实测技术参数.在使用分析纯无水乙醇做溶液情况下,对比了正常/硫熏样品浸出液,硫磺浸出液/无水乙醇的透过率光谱,得出含硫浸出液在715 nm和835 nm处具有特征吸收峰,可作为硫磺熏蒸样品检测判据.利用研制的样机对正常/熏硫党参、枸杞样品进行了测试,测试结果表明可区分样品是否经过硫磺熏蒸.

Abstract: A kind of fast detecting device was developed for Chinese medicinal herbs based on visible and near-infrared spectroscopy technology.It is mainly composed of the lithium battery,DC/DC converter circuit,constant current source,light source,sample pool,micro fiber spectrometer,laptop and so on.This paper describes the components and working principle of the instrument,gives the constant current driving circuit principle diagram of the halogen tungsten lamp,and introduces its working principle and the measured technical parameters in details.The paper compared the normal and sulfur smoked sample extracts spectra,and found sulfur leaching solution in 715 nm and 835 nm has the characteristic absorption peak.It can be taken as the criterion of sulfur fumigation sample detection.Normal / smoked sulfur Codonopsis pilosula and wolfberry fruit samples were tested by the prototype.The test results show the sample with sulfur fumigation can be distinguished.It is expected to be used for sulfur smoked in the medicinal field for rapid screening test of sulfur smoked herds.

Key words: Sulfur smoked, chinese herbal medicine, check, on site, spectrum, characteristic peaks
