## Rejection of the standard curve [Bioanalytics]

Hello Ayman,

» We conclude that the blank with IS sample was contaminated during handling while the other samples are not contaminated.

Or it could be crosstalk. Or your deuterated IS (if that is what you have) is not very pure but contains interfering amounts of analyte.

This week's list of things I absolutely detest: Corona virus, the which function in R, WIA-WIA interfaces for scanning under Windows 10, the Bee Gees, the smell of my fridge.

Best regards,
