Description
Technical field [0001] The invention relates to a method for analyzing tobacco pollutants by thin-layer chromatography coupled with infrared technology, and belongs to the technical field of physical chemical inspection of tobacco pollution. Background technique [0002] Thin layer chromatography (TLC), also called thin layer chromatography, is one of the earliest chromatographic techniques invented. It is widely used in the separation and identification of various natural and synthetic organic substances, and also used in the purification of small amounts of substances. It has many advantages such as simple operation, fast separation speed and high efficiency. Generally speaking, thin-layer chromatography mainly includes operation methods such as preparation of thin-layer plates, dropping of samples, unfolding, color development, comparison of Rf values, and quantitative analysis. However, because the preparation of thin-layer boards is more complicated and it is difficult to e...
