1 Scope
GB/T 5275 provisions of this section from a pure gas or gas mixture through a syringe to the other balance calibration gas is continuously injected components, from
Continuously prepared containing two or more components of the gas mixture with the calibration methods.
Use premixed gas instead of pure gas (see Appendix A) can be prepared in a mixed gas volume fraction low. Determine the volume fraction of the volume flow,
By a single flow of gas is calculated, it may also be an appropriate method of independent measurements given in ISO 6145-1.
Advantage of continuous injection law can be prepared continuously large number of mixed gas, and as long as the appropriate number of syringes or single syringe
Known multi-component gas mixture containing the gas can be as prepared as easily as binary mixtures prepared multi-component gas mixture. The method may further
By a few steps and easily increase calibration components in a mixed gas volume fraction. Therefore, it can be used to evaluate a gas analyzer
Some other features, such as the limit of detection, blind and accuracy. Binary mixed gas prepared by the method (coverage factor k = 2) relative expanded
Uncertainty of 5%, the scope of 10-5 to 10-2 (volume fraction).

Principle 3
Component calibration gas or liquid phase by syringe into the capillaries and then into the gas stream balance, the capillary can be a needle injection device
Vials, syringes, pistons driven by a suitable variable speed motor.
A component in the gas mixed with the balance gas volume fraction φA B by the formula (1) is given by.
φA = qA/(qA qB) (1)
Where.
qA --- calibration component A volume flow;
Gas volume flow qB --- balance of B.
If the calibration component is injected as a liquid, the gas flow rate after the volatile by the formula (2) is given by.
qA = (qA, l × ρA, l)/ρA, g (2)
Where.
qA, l --- injection volume flow rate of liquid, which is the same unit of measure qA;
