Technical Field
The utility model relates to the technical field of detection equipment, in particular to an auxiliary feeding device for a gas chromatograph.
Background
Gas chromatographs are detection instruments that utilize chromatographic separation techniques and detection techniques to perform qualitative and quantitative analysis of complex mixtures of multiple components. Gas chromatographs are commonly used to analyze organic materials that are thermally stable in the soil and have boiling points no greater than 500 ℃, such as volatile organic compounds, organic chlorides, organic phosphites, polycyclic aromatic hydrocarbons, phthalate esters, and the like.
The feeding method of the gas chromatograph in the prior art comprises two modes of manual feeding and automatic feeding. In the manual feeding method, an operator is required to manually inject a sample into the gas chromatograph, and the speed of each sample injection is difficult to be kept uniform, so that the reproducibility of detection is also poor. In the automatic feeding method, the gas chromatograph is fed by matching the feeding tray for placing the glass bottles with the movable absorber, and the specific working principle is that the feeding tray rotates the glass bottles to a feeding station of the movable absorber, the movable absorber moves to the position above the glass bottles to be fed, and then the movable absorber moves downwards to absorb the glass bottles, so that the automatic feeding method has better detection reproducibility. However, since the period of each detection of the gas chromatograph in the automatic feeding method is long (more than 10 minutes are required), the standby time of the loading tray is long, and the loading can be performed again only by sucking all the glass bottles on the loading tray, which affects the detection time.
