Background technique
Chromatograph, for the device for carrying out chromatographic isolation analysis, including at sampling system, detection system, record and data
Reason system, temperature control system and mobile phase control system etc., modern chromatograph have stability, sensitivity, versatility and from
The features such as dynamicization degree is high has gas chromatograph, liquid chromatograph and gel permeation chrommatograph etc., these being widely used for of chromatograph
Product, the analysis of certain content of high molecular material are learned, gel chromatography can also measure the molecular weight of high molecular material and its divide
Cloth, chromatographic earliest application are for separating plant pigment, and method is such that be put into calcium carbonate in a glass tube,
To be poured into pipe containing the petroleum ether of phytochrome (extracting solution of leaves of plants), at this point, the upper end of glass tube occur immediately it is several
Then the mixed spectrum band of color is rinsed with pure petroleum ether, with the addition of petroleum ether, bands of a spectrum are constantly moved down, and gradually
Be separated into the bands of a spectrum of several different colours, continue to rinse can connect respectively various colors pigment, and can be identified respectively,
Chromatography is also gained the name therefrom.
Gas chromatograph refers to the chromatography instrument for using gas as mobile phase, and principle is mainly to utilize the boiling of substance
The difference of point, polarity and adsorption property realizes the separation of mixture, and sample to be analysed is after vaporizer gasification by inert gas band
Enter in chromatographic column, liquid or solid stationary phase is contained in column, each component tends between mobile phase and stationary phase in sample
Form distribution or adsorption equilibrium, with the flowing of carrier gas, sample component carry out during exercise repeated multiple times distribution or absorption and
Desorption distributes the big component of concentration in carrier gas and first flows out chromatographic column, and flows out after distributing the big component of concentration in stationary phase,
Traditional gas chromatograph is not readily portable, needs user to clasp and moves, however consumes manpower and material resources excessively, is not easy to
The use of user solves the problems, such as mobile if installation universal wheel etc. mobile mechanisms, and there is also propped up using universal wheel
Support is unstable in the presence of placing, and particular for using under outdoor environment, when encountering outdoor ground out-of-flatness, then will appear placement
Unstable, placing unstable rule causes to be unfavorable for sample to carry out injection work, is easy so that leakage problem occurs when sample injects,
