Plasma went out unexpectedly.
If this happened during ignition, try the following:
? Observe the plasma discharge during ignition through the
viewing window. If the plasma lights, but then extinguishes
right away, check the argon flows, torch condition, and test
for air leaks.
? If the sample is very volatile, try a less volatile sample or
switch to water.
? If analyzing volatile samples, a higher power setting and
lower nebulizer gas flow rate may be required.
If this happened during normal operation then the plasma
detection circuit that monitors the plasma is the most likely
problem. If you continue to have problems, contact
PerkinElmer service and arrange a service visit.

这个问题有谁遇到过？
先是测样过程中突然熄火
重新点火，基本20秒内又熄火了

今天晚上遇到了。 显示出现切割器的问题，后来就出现这个问题。后来在点火前，开泵，对管路进行清洗一段时间，然后重新点火。就没有问题了。 不知道对仪器有没有影响。
我今天就是分析某一个样品出现这个问题，可是样品的固体浓度应该也不会很高，大概在0.8%左右。不知道是什么原因，打算再稀释一下，然后改天再做做看。
