Dataset for Unified acidity of liquid chromatography mobile phases with methanol and acetonitrile

Dataset for article "Unified acidity of liquid chromatography mobile phases with methanol and acetonitrile". Here we report the data of 78 reversed-phase liquid chromatography-mass spectrometry mobile phases that were determined by potential differences in a symmetric cell with two glass electrode half-cells and almost ideal ionic liquid triethylamylammonium bis((trifluoromethyl)sulfonyl)imide [N₂₂₂₅][NTf₂] salt bridge with multiple overlapping measurements. In addition, for 45 of these mobile phases, the potential difference between a glass and a double junction reference electrode were measured. Procedures used with Keysight B2987A Electrometer are given in dx.doi.org/10.17504/protocols.io.n92ld9dj8g5b/v2 and dx.doi.org/10.17504/protocols.io.byh2pt8e. For other instruments, the procedures differ by software and instrument connections.《甲醇与乙腈体系液相色谱流动相统一酸度》论文配套数据集。本数据集收录了78组反相液相色谱-质谱联用（reversed-phase liquid chromatography-mass spectrometry）流动相的测定数据，所有数据通过带有两个玻璃电极半池（glass electrode half-cells）的对称电解池、近乎理想的离子液体三乙基戊基铵双(三氟甲基磺酰)亚胺[N₂₂₂₅][NTf₂]盐桥（salt bridge）测得，并开展了多次重复测量。此外，针对其中45种流动相，还测定了玻璃电极与双接界参比电极（double junction reference electrode）之间的电位差。使用Keysight B2987A静电计（Electrometer）的操作流程已发布于dx.doi.org/10.17504/protocols.io.n92ld9dj8g5b/v2与dx.doi.org/10.17504/protocols.io.byh2pt8e。针对其他型号仪器，操作流程因所用软件与仪器连接方式不同而存在差异。
