Varian 的MS, 一直用FID,今天启用MS的时候,连接好,punm down,检测了一下仪器的状态。一切正常除了ion gauge 有点问题。说是 Ion Gauge test failed。 也不知道ion gauge 是干啥用的。 论坛上搜了一下貌似没有相关的问题出现,请教各位大侠,是不是由于 water content 太多引起的, bake out MS以后就没问题了? 多谢
11:45:29 Ion Gauge Test: FAILED 11:45:29 THE ION GAUGE READING DOES NOT SUBSTANTIALLY CHANGE WHEN THE ION GAUGE IS TURNED 11:45:29 ON. LIKELY CAUSES INCLUDE: 1) THE ION GAUGE IS DEFECTIVE (COLLECTOR SHORTED TO 11:45:29 GROUND) OR 2) THE MANIFOLD ELECTRONICS ASSEMBLY IS DEFECTIVE (ION GAUGE 11:45:29 ELECTROMETER).
