Title: Cold vapor for Mercury has no signal
Post by: thohry on August 29, 2015, 12:25:47 AM

Hi all,

We are running Cold Vapor AAS for Hg Analysis. After some time not using it, we start to use it for Hg again and now there is no signal (or very low).
W check almost every thing (replace std, NaBH4, acid, new lamp, new cell..) but could not find out.
Could anybody farmiliar with this technique show me what can be the cause of no signal

Thanks for any inputs.
