Description

Technical Field

[0001] The utility model belongs to the technical field of spraying devices, and in particular relates to a multifunctional biochemical spraying instrument. Background Art

[0002] Commonly used planar chromatography spray devices are mainly divided into contact spray devices and non-contact spray devices. The non-contact spray device uses a motor-driven micro-syringe for spraying, and uses nitrogen (or compressed air) to micro-flow the sample and spray the sample onto the thin layer plate to form strips. Among the spray devices used for planar chromatography, the non-contact purge spray device has more advantages. It can achieve a variety of sample spray volumes of different volumes, and evaporate the sample solvent at the same time during the spraying process to reduce the diffusion of the strips and make the sample distribution more concentrated, which is conducive to separation and subsequent quantitative analysis.
