The translation program preserves the elution order for each compound, so that identification of each peak does not have to be repeated. 这一转换程序保留了每种化合物的流出顺序,无须再对每一个峰进行认定。
Octadecane has good resolving power for ethylbenzene and p-xylene, but it reverts the elution order of o-and m-xylene and its retarding force for o-xylene is not strong. It has been found that the elution order of solutes varies with the pH value of mobile phase. 十八烷可以很好地分离乙苯和对二甲苯,但邻二甲苯在间二甲苯以后流出,而且它对于邻二甲苯的滞留作用不强。研究表明,不同的pH,溶质的流出次序发生改变。
The recognition ability of the 4 aminopyridine molecular imprinted polymer was affected by the acetonitrile content so strongly that the elution order of the solutes might be reversed. 发现有机添加剂的含量对印迹聚合物的印迹识别能力影响很大,甚至能改变混合物的流出顺序。
It has been found that the elution order of solutes varies with the pH value of mobile phase. 研究表明,不同的pH,溶质的流出次序发生改变。
The concepts of response factor and average response factor were put forward. The mathematic models for predicting of substance retention time, elution order, efficiency of separation and for the choice of optimized elution conditions were also established. 提出了响应系数和平均响应系数的概念,通过建立反映各参数变化的数学模型,预测物质保留时间、洗脱顺序及分离效果,选择最佳洗脱条件。
Extraction tests were made with Grade ⅱ a activated silica gel. The ratio of the sample to the adsorbent was 1:30. In the two eluants, the ratio of ethyl acetate or acetone to benzene depended on the elution order. 提制试验是用Ⅱa级活性硅胶进行的,样品与硅胶之比为1:30。在两种洗脱剂系统中,乙酸乙酯或丙酮对苯的比例根据试验的洗脱顺序而定。
The separated bands of carbon dioxide mix with a stream of pumped-in distilled water in a T-tube and then flow, in GC elution order, through a conductance cell of an electrolytic conductance detector for quantitative detection. 载气中各组分生成的CO2在T-形管内与用泵输入的蒸馏水相混后仍然保持互相分离,逐一依色谱流出顺序进入电导检测器进行测定。
The elution order was determined by a circular dichroism ( CD) detector. 圆二色(CD)检测器确定了对映体的出峰顺序并测定了圆二色特性。
For this very reason, we further studied the elution effect by different concentration ethanol aqueous in order to enhance the purity of triterpene acids in final production. 为此,我们进一步研究了不同浓度乙醇洗脱液对杂质的洗脱性能,进而提高产品中三萜酸的纯度。
