LC-MS analysis of Al standard
Posted: Tue Feb 22, 2011 1:06 pm
Hey all
I have a general problem regarding the use of a RP C-18 column.
When i try to analyse a standard solution of Aluminium i do not get any signal at the ICP-MS (ELAN 6000) when i use the RP column.
If i remove the column and inject the same volume and concentration of aluminium standard solution i get a clear peak.
Do anyone have an idea to why i dont get a signal for aluminium when i use the RP column. It should pass right throug the column without any retention?
