Embodiment Construction

[0084] In the following, the present invention will be further described by using the following embodiments in conjunction with the accompanying drawings.

[0085] figure 1 It is a structural block diagram of the chromatographic analyzer of the present invention, and the chromatographic analyzer is composed of six parts: a carrier gas system, a sampling system, a separation system, a detection system, a recording analysis system and a temperature control system.

[0086] Such as figure 2 As shown, the carrier gas system includes a gas source, a gas purification device, and a gas path control system. Its function is to provide a stable and adjustable gas flow to ensure the normal operation of the gas chromatograph. Wherein, the gas purification device is composed of three gas purification tubes, which are respectively used to purify the carrier gas, air and hydrogen, and can filter and purify the three gases at the same time. The filler used in the purifier connected to the...

Abstract

The invention discloses a chromatographic analyzer, in particular to a gas phase chromatographic analyzer. The chromatographic analyzer comprises a carrier gas system, a sample feeding system, a separation system, a detection system, a recording and analyzing system and a temperature control system. The carrier gas system comprises a gas purifying device. The chromatographic analyzer can be used for filtering and purifying three gases for a gas phase chromatography, so that the gas entering the device is higher in analysis purity, the problems that the existing chromatographic analyzer is low in sensitivity, high in detection difficulty and poor in repeatability can be solved, and the chromatographic analyzer is particularly suitable for detecting and analyzing transformer oil.

Description

technical field [0001] The invention belongs to the field of chromatographic analyzers, in particular to a gas chromatographic analyzer. Background technique [0002] Chromatography analyzer is an instrument that applies chromatography to qualitatively and quantitatively analyze substances, and to study the physical and chemical properties of substances. It includes carrier gas system, sampling system, detection system, recording and data processing system, temperature control system and mobile phase control system, etc. These chromatographs are widely used in the analysis of chemical products and certain content of polymer materials, and gel chromatography can also determine the molecular weight and distribution of polymer materials. [0003] The existing chromatographic analysis technology has been continuing to use the SP3430 model instrument in the 1990s. This equipment has good performance and better meets the needs of safe production. With the progress of the times, ...
