Abstract

The invention provides a chromatographic device and a working method thereof. The chromatographic device comprises a base, an upper cover, a heating part, a temperature measurement parts, two fixed units and an accommodation unit, wherein the fixed units are fixed on the base and respectively fix both ends of a chromatographic column in a compressing mode; the accommodation unit comprises a firstblocking part, a second blocking part and a third blocking part; the first blocking part is fixed on the base and extends along a vertical direction; the second blocking part is arranged on the base on the periphery of the first blocking part and extends along the vertical direction; the third blocking part is arranged at the upper part of the base and extends to the first blocking part from the second blocking part; and the fixed units and the accommodation unit are positioned in a space formed by surrounding of the base and the upper cover. The chromatographic device has the advantages of heating uniformity, simplicity and convenience for operation, good detection parallelism and the like.

Description

technical field [0001] The invention relates to chromatography, in particular to a chromatographic device for heating a chromatographic column and a working method thereof. Background technique [0002] The heat tracing of Nano ESI's chromatographic column can significantly improve the sensitivity and signal-to-noise ratio of organic matter analysis, and has wide application and scientific research value. [0003] The existing chromatographic columns are all coated quartz capillaries, which have very good toughness and can be wound freely like electric wires. The heat tracing device cannot guarantee the consistency of the use environment in terms of heat preservation, and the heating structure cannot be constant and uniform. Heating requires high operability, resulting in high technical requirements and expensive replacement costs. For example, the existing chromatographic column heat tracing (also called chromatographic column thermostat) of Thermoelectric Nano ESI needs t...
