Gas chromatograph and its data processor

Abstract

The invention discloses a data processor comprising a printer, the printer comprises a support, a motor and a printer gear, wherein an output shaft of the motor penetrates through the support, and an outer shell of the motor is fixed on the support. The printer gear is connected with the output shaft of the motor, and a protective cover is further arranged on the support and surrounds the printer gear. The invention further provides a gas chromatograph provided with the data processor. Due to the fact that the protective cover is arranged on the support and surrounds the printer gear, paper scraps brought down in a paper feeding process can be effectively prevented from falling on the printer gear, and the occurrence rate of the paper-jam phenomenon can be reduced, so that the fault rate of the gas chromatograph is reduced, and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of gas chromatographs, in particular to a gas chromatograph and a data processor thereof. Background technique [0002] Gas chromatograph is an instrument for qualitative and quantitative analysis of substances by gas chromatography. It is widely used in petroleum, chemical industry, biochemistry, medicine and health, food industry, environmental protection and other fields. In addition to quantitative and qualitative analysis, gas chromatography can also determine the physical and chemical constants of the sample on the stationary phase, such as distribution coefficient, activity coefficient, molecular weight and specific surface area. [0003] The data processor is the data processing system of the gas chromatograph, which is used to faithfully convert the output analog signal of the gas chromatograph into a digital signal and send it to a special computer for storage. Carry out operations such as peak ju...

Problems solved by technology

The above printers use 241-185 printing paper, which is printing paper with holes on the torn edge. The holes on the printing paper are machined, but although some holes are punched through, the paper scraps do not fall off, and the paper will be damaged during the paper feeding process. It was brought down by the big gear that feeds the paper, and just fell on the gear of the printer directly below it, causing the printer to be stuck and causing its control circuit board to be overloaded, causing some components to burn out, resulting in a data processor failure. Due to the repair cycle of the instrument It takes too long (about one month) and the repair cost is too large (about 3000-5000 yuan each time), which will eventually affect the use of the instrument and increase the operating cost
