Method of Test for Residual Oxygen in the Packing of Infusion Method of Test for Analysis of Headspace Gas of Summary Packing of Infusion: Gas analysis headspace for infusion packings, especially analysis of residual oxygen of infusion packings, directly related to the product quality during period of the quality assurance. With aid of Analyzer Headspace HGA-01 and special instrument of sampling developed for the Labthink Instruments Co., Ltd. (www.labthink.cn), test of residual oxygen in the infusion packings, also bottles and bags of infusion can be decided convenientamente, eficientamente and economically. Then, test for bag of infusion can perfectly be carried through. Word-key: packing of infusion, bag IV, bag of infusion, bottle of infusion, residual oxygnio, analysis of residual oxygen, gas analysis headspace. 1.Significao for Control of Residual Oxygen of Bottles and Bag of Infusion Oxygen is one of the important factors that it affects the period of the quality assurance of infusion packings.

As research, effective control of tax of gas composition in the bag interior and bottles of infusion can help to draw out period of the quality assurance and to promote quality of storage. To reduce certain contented of gas in the interior of infusion packings, MAP and CAP had been applied widely in the industry. Inert gases that make effect more important to draw out period of the quality assurance are nitrogen gas, or composition of nitrogen and dioxide carbon. But after packing sealing to exist always a certain amount of other gases in the interior of infusion packings, as oxygen. These gas ingredients could result in additional change of composition in the interior of packing with the death of the time. Then, a complete control of contented is very difficult of gas in the packing interior, that could bring difficulties to the analysis of quality of product, esteem of period of the quality assurance and evaluation of design of packing.
