2.1 The remaining amount residuallevel

Left in the container to the quality or quantity of surplus product manometer. This amount should be minimized in order to minimize the gas filling the last high

Influence of impurity content production process.

2.2 Storage period shelflife

From the time the analysis is complete, the supplier of gas quality guarantee period. Within this period, should ensure that an accurate analysis of impurities over

Technical indicators remain at or below the upper level of a particular gas regulations.

2.3 Blood stem liquiddry

All liquefied gas liquid runs out.

3.1 Special factors affect gas storage period

Stability and coexistence of different substances 3.1.3 gas

--- Gas and impurities;

--- Gas and packaging materials.

3.1.4

Analysis and filling operations.

3.1.5

Transport and storage conditions.

3.1.6

the amount of container products.

3.1.7

valve tightness of the gas reservoir is to determine the critical factor, particularly for the low pressure gas. In order to improve the gas with different composition

Coexistence stability quality, should first purified gas to a certain extent, so that the impurities contained no change over time, should also choose the right

Packaging Materials. Before the filling of the inner surface of the container the chemical, physical, or passivation treatment to be effective in reducing the reaction time and with the continuation of production
