Embodiment Construction

[0062] figure 1 It is a schematic diagram showing a configuration example of a gas chromatograph according to an embodiment of the present invention. This gas chromatograph is an instrument for performing analysis by supplying a carrier gas together with sample components into a column 1, and includes a column oven 2, a gas introduction part 3, and a detector in addition to the column 1. 4 etc.

[0063] The chromatography column 1 includes, for example, a capillary column, and is heated in a column oven 2 during analysis. The carrier gas is supplied into the column 1 together with each sample component from the gas introduction part 3 through the column inlet 5 . Each sample component is separated while passing through the chromatography column 1 and detected by the detector 4 . The detector 4 may include various detectors such as a hydrogen flame ionization detector (FID).

[0064]Inside the column oven 2, a heater (heater) 21, a fan 22, and the like are installed. The h...

Abstract

The present invention provides a gas chromatograph capable of reducing gas or electricity consumption easily and efficiently. This gas chromatograph is configured as follows: by selecting the general setting key (325), it is possible to collectively change the setting values ​​related to various functions used to reduce gas consumption, and the settings related to various functions used to reduce electric consumption. at least one of the function-related setting values. Thereby, even an inexperienced user can easily set the setting values ​​related to various functions to appropriate values, so that the consumption of gas or electricity can be easily and efficiently reduced.

Description

technical field [0001] The present invention relates to a gas chromatograph for performing analysis by supplying a carrier gas into a chromatographic column (column) together with sample components. Background technique [0002] In a gas chromatograph, a carrier gas is supplied to a column together with sample components, and each component is separated while the carrier gas passes through the column. After the carrier gas is mixed with the sample components in the sample gasification chamber, it is supplied into the column from the column inlet. [0003] A gas chromatograph includes a column oven, and during analysis, a carrier gas can be supplied into the column while heating the column in the column oven. In the column oven, for example, a fan for stirring air is installed. During the analysis process, the temperature distribution in the column oven can be kept uniform by driving the fan. [0004] Usually, parameters related to the flow rate of the carrier gas in the c...
