Web16 aug. 2013 · by Analisis » Sat Jan 21, 2012 2:08 am. Hi, I have done this analysis with an ECD but not with an NPD. The question is how much is your detection level in an NPD. With ECD we can get easily to 0.3 ppm and we get a good peak. I don't know if you can get the same level of detection with an NPD. I am interested in your question because we have … WebNPD ceramic insulator. 필요시 교체 : 5182-9722. NPD ceramic insulator kit.
