Abstract

The invention discloses a standard gas generation system and a method for dynamically monitoring standard gas, wherein the standard gas generation system comprises a standard gas generator, a first exhaust branch circuit, a second exhaust branch circuit, a gas sensor, a processor and a prompt device, the first and the second exhaust branch circuits are connected with an exhaust port of the standard gas generator, the gas sensor is connected with the first exhaust branch circuit and can measure the calibration of exhaust gas, and the processor can obtain a gas concentration initial value, a gas concentration measured value of the gas sensor, and compares the gas concentration initial value and the gas concentration measured value. When a difference value of the gas concentration initial value and the gas concentration measured value exceeds a preset threshold, the prompt device outputs promote information. The standard gas generation system can guarantee accuracy and stability of the standard gas generator.

Description

technical field [0001] The invention relates to the technical field of gas sample preparation equipment, in particular to a standard gas generating system and a standard gas dynamic monitoring method. Background technique [0002] The standard gas generator is an instrument that dilutes the standard gas of known concentration into the required concentration standard sample gas in proportion to the volume. The standard gas generator has been widely used in chemical analysis laboratories, instrument R & D and manufacturing laboratories , power plants, petrochemical plants, air separation plants and other fields, because the standard gas generator can produce various concentrations of standard gas, it can also be used to precisely control the gas flow. [0003] With the increasingly serious environmental pollution, the standard gas generator is also used in the gas monitoring system. The core component of the gas on-line monitoring system is the gas analysis unit, and the accur...
