微分电化学质谱仪简介

质谱仪是一种鉴别物质成分强大的仪器，可以用于气体分析，其优势是从质量数最小的氢气分子到分子量几百的大分子有机蒸汽等，均可分析，是万能气体分析仪，具有检测限低，灵敏度高，线性范围宽，所需气体消耗量少等优点，同时可以进行同位素标记等优点，可广泛应用于各类电池气体分析。

原位电化学质谱也被称为在线电化学质谱，差分电化学质谱，DEMS，OLEMS等，可用于锂离子电池等各类储能器件充放电过程中的产气在线分析，对于气体消耗的电池类型，如空气电池，可用于电池气体消耗的定量分析，可以实时分析电池运行的不同阶段气体生成或消耗的情况，即获得电池充放电过程中气体生成或消耗随电压变化的分布情况，是研究电池电化学反应机理，快速筛选电极材料，评价电解液分解等重要分析工具之一。
