前文用NaNO_3和NH_4NO_3两种硝酸盐作为探头所测定的反相离子对色谱的死时间,在柱温、流速一定的情况下,并非一常数,而是随着流动相的有机溶剂的含量、离子对试剂的浓度而变化的。前文认为其可能的原因是离子对试剂在固定相上的吸附作用。本文对此将作进一步的探讨。 本文研究了用四丁基碘化铵(TBAI)和十二烷基硫酸钠(SLS)作离子对试剂,以重水(D_2O)作探头时,离子对试剂浓度、甲醇含量、进样量对D_2O保留值的影响,并与以NaNO_3作探头时以上因素对保留值的相
Precursor NaNO_3 and NH_4NO_3 two nitrate as a probe determined by the reverse phase ion chromatography of the dead time at a constant flow rate, the flow rate is not constant, but with the mobile phase of the organic solvent content, ions The concentration of the reagent varies. The reason why the previous article considers it possible is that the adsorption of the reagent on the stationary phase is performed by the ion pair. This article will be further discussed. In this paper, the effects of ion pair reagent concentration, methanol content and injection volume on D 2 O (superscript 2 +) concentration were investigated using tetrabutylammonium iodide (TBAI) and sodium lauryl sulfate (SLS) The effect of retaining the value, and with NaNO_3 as the probe when the above factor on the retention of the phase
