[question] standard curves of mixture standards

[dhan]

Hi,

I am wondering to know whether I can make mixture of standards (five standards) to develop standard curves for all in single injection. (or) do I have to develop standard curve for one standard at a time.

I am using Agilent GC-MS 6890N/5975.

Thank you,

Dhan

It is quite common to have mixtures of standards, but at some point you should inject them individually to make sure that none of them have degradants or other contaminants that might interfere with one of the other standards.
