在LC-MS离子源部分，需要用到大流量、高纯度（95%以上）的氮气，这种氮气需在特定压力下作为雾化、干燥等气体使用。此外，部分厂商也会选择使用满足特定要求的干燥空气。需要注意的是，气源不得与目标物发生反应，也不得引入其他杂质，以免影响质谱的运行。同时，气源也不应增加离子源的维护和清洁工作。氮气的流量、纯度、质量以及供气系统的稳定性等因素，都对质谱的运行至关重要。因此，在选择气源时，需要仔细考虑这些因素，以确保质谱的稳定性。

氮吹是一种广泛应用于实验室的样品前处理方法。借助氮吹仪或浓缩仪，我们可以持续且可控地将氮气吹向样品表面。这一过程可以促使样品中的溶剂迅速蒸发，进而实现样品的浓缩。根据加热方式的不同，氮吹仪可分为干式、水浴式和空气浴三种。全自动氮吹仪广泛用到氮气发生器，能够持续稳定的提供氮气。

蒸发光散射检测器，简称ELSD，是一种HPLC检测器，其工作原理基于雾化-气溶胶技术。它特别适用于检测挥发性洗脱液中的非挥发性样品组分。在喷雾蒸发过程中，气体的压力、流量、样品的浓度以及洗脱溶剂的选择都起着至关重要的作用。
通常，氮气被用作这种检测器的气体来源。在整个分析过程中，需确保气体的纯度（达99.5%）和压力保持恒定。气体的流速一般控制在0.5至5.0升/分钟之间，这一设置与溶剂的挥发性、色谱柱的流速等因素密切相关。同时，气体必须保持清洁、干燥和惰性，以防止产生较高的背景噪音，从而确保检测结果的准确性和可靠性。

电雾式检测器，作为一种通用型检测工具，展现出了极高的灵敏度和卓越的重复性。它广泛应用于检测多种不挥发性和半挥发性的有机物，如药物成分、天然产物、糖类、蛋白质以及表面活性剂等。这一广泛的适用性使得电雾式检测器在分析领域扮演着重要角色。
在电雾式检测器的工作过程中，氮气发挥着至关重要的作用。它不仅能够实现样品的雾化干燥，还通过碰撞使样品带电。氮气的纯度越高（达99.5%）、稳定性越好，电雾式检测器就能达到更高的灵敏度和更低的检测极限。这不仅确保了检测结果的准确性，还进一步保证了结果的重复性和稳定性。因此，氮气的质量对于电雾式检测器的性能至关重要。
