Although most workers have found that samples containing ionizable components usually are best separated with mobile phases that have a pH less than or equal to 3 , some separations may be impossible at a low pH because components of the sample are unstable at a low pH; protonated basic compounds are eluted too soon; and required band spacings are unobtainable.

尽管许多工作者发现含有离子化组分的样品在流动相pH值低于或等于3的时候有最佳的分离，但许多样品不可能在低pH下分离，因为样品中组分在低PH下不稳定、质子化的生物碱洗脱太快、和不能达到要求的峰间距。

Under isocratic elution condition including pH of the buffer solution, separation voltage and the ratio of organic solvent in the buffer solution.

首先以等位冲堤的方式，寻找最佳的实验参数，其参数包含缓冲溶液酸碱值，操作电压及有机修饰剂在缓冲溶液中的比例。

Among those results,the efficiency of leuconostoc mesentervides was the best one; and the nitrite peak was inhibited clearly by adding garlic juice or ginger juice during fermentation.

结果表明：采用纯接种技术，在发酵前期可有效降低亚硝酸盐的含量，其中以接种肠膜明串珠菌效果最佳；同时在发酵过程中添加适量蒜汁或姜汁，可明显地抑制甘蓝乳酸发酵中亚硝峰出现；且在发酵过程中，泡菜的pH值对亚硝酸盐含量也有较大的影响。

The best liminal value range :-800±100~±200Hu.
