Analysis of Alcohols in Gasoline by Gas Chromatography Multidimensional Chromatography

Analysis of Alcohols in Gasoline by Gas Chromatography Multidimensional Chromatography

Characteristics of gasoline analysis gas chromatograph instrument:

The instrument can be equipped with capillary columns of different specifications (with a diameter of 0.2-0.53mm), and its reasonable capillary injection system design (with split/non split injection, diaphragm blowing, and tail blowing systems) results in small out of column effects and high column efficiency; To achieve a peak shape with high chromatographic peak height, narrow half peak, and no tailing, thus obtaining accurate and good repeatability quantitative results.

The instrument adopts unit modular design, making installation simple and maintenance more convenient; new-typeFIDWith lower detection limits, it is easy to disassemble and clean the nozzle and ion collection electrode. The precisely fixed emitter installation structure ensures high consistency in the performance of each instrument.

The gas path adopts a dual design of first stabilizing the voltage and then stabilizing the current; Stable regulation mode, with high precision, high reliability, and convenient and intuitive flow regulation. Equipped with gas/gas leakage protection and prompt function, it can automatically cut off TCD bridge current, providing maximum protection for rhenium tungsten wire from damage.

Equipped with six temperature control systems, including column chamber, gasification chamber, detection chamber, converter, and external control events.

It has a five order linear program heating function, which can meet the analysis of multi-component samples.

Equipped with power-off protection, over temperature protection, and power on self-test function
