Hello everyone! I have a mixed standard solution of aflatoxins (B1,B2,G1,G2) of LGC standards in acetonitrile and I was wondering if it is ok to use it as it is without drying it, or adding toluene, methanol, etc. All the methods I have read (ISO, AOAC) say that I have to dry it and then dilute it again in a toluene-acetonitrile solution. For mobile phase i use methanol, water and acetonitrile and for my samples only methanol. I m new in doing aflatoxins analysis so I would appreciate it if you could share your experience with me.

Thank you all in advance.
