Description
Technical field
The utility model relates to a kind of teaching aid technical field, particularly relates to a kind of educational chromatograph.
Background technology
Gas chromatograph is applied very wide in oil, chemical industry, biological chemistry, medical and health, food industry, environmental protection etc.It is except for quantitatively and except qualitative analysis, can also the physicochemical constant such as the partition factor of working sample on Stationary liquid, activity coefficient, molecular weight and specific surface area.A kind of carrying out each component in mixed gas analyzes the instrument detected.
Chromatograph utilizes chromatographic column to be first separated by potpourri, then utilizes detecting device to detect the component separated successively.The diameter of chromatographic column is several millimeters, is wherein filled with solid adsorbent or liquid flux, and the adsorbent of filling or solvent are called Stationary liquid.Corresponding with Stationary liquid also has a mobile phase.Mobile phase is a kind of gas do not reacted with sample and Stationary liquid, is generally nitrogen or hydrogen.Sample to be analyzed injects mobile phase on chromatographic column top, and mobile phase enters chromatographic column with sample, therefore mobile phase is also called carrier gas.Carrier gas is flow through chromatographic column with certain flow rate continuously in analytic process; Sample then just injects again and again, often injects and once obtains an analysis result.It is difference based on macroscopic property that sample is separated in the chromatography column.Stationary liquid and each component in sample have different affinity (be that absorption affinity different to gas-solid chromatography (GSC) instrument, be different solubility to gas-liquid partition chromatography instrument).When carrier gas with sample continually by chromatographic column time, the large component of affinity in the chromatography column translational speed is slow because affinity to mean that greatly Stationary liquid holds its strength large.Then moving that affinity is little is fast.Detecting device, to the signal given by each component, registering instrument shows as peak one by one, is called chromatographic peak.Maximum value on chromatographic peak is the foundation of qualitative analysis, and the area that chromatographic peak covers then depends on the content of corresponding component, therefore peak area is the foundation of quantitative test.After a blend sample is injected, the curve obtained by registering instrument record, is called chromatogram.Analyze chromatogram and just can obtain qualitative analysis and quantitative analysis results., there is risk of leakage in current existing chromatograph inconvenient operation.
