同时测定包装中O_2与CO_2比例含量的顶空分析技术的研究

Simultaneous Determination of Oxygen and Carbon Dioxide Abundance Ratio in Package by Headspace Gas Analysis Technique

通过抽样时间以及样气分析时间的选择条件试验,测试了多种形式包装的不同样品中O2与CO2的比例含量,验证了同时测定包装中O2与CO2比例含量的顶空分析技术,在食品、药品包装中的应用范围及测试数据的稳定性。为需要调整包装内部气体成分比例的食品、药品生产行业以及研究机构提供参考。

Oxygen and carbon dioxide abundance ratio of sample with different packaged form were tested with selective test of sampling time and analysis time. Stability and application scope of headspace gas analysis technique for simultaneous determination of oxygen and carbon dioxide abundance ratio in food or pharmaceutical package was verified. The purpose was to provide reference for food, drug manufacturing enterprise or research institute on adjusting appropriate proportion of gases in package.
