Yes, I meant detection limit. In my sample I have a second phase which dissolves at some temperature. I tried to identify the dissolution temperature using XRD. With increasing temperature the peak intensity for the second phase decreased. After certain temperature the peak disappeared. I understand that is not exactly the dissolution temperature. There is a limit of XRD to detect the phase.
