how to remove "reject " selection from a calibration curve?

Hello,

You can reject or unreject a standard in the calibration curve pane of online or offline data analysis. Make sure you click "Process Batch" and save after doing this. Please see screen capture below. The software does not automatically reject curve points, it must have been accidently selected or carried over from a previous batch. The green dots mean the instrument measured the standard in Analog mode. The blue dots were measured in Pulse mode. Hope this helps

Hi Johnkane, 

Thank you for answering my question. 

I tried i . It works. 

I also noticed Analog mode is usually used in high concentrations. 

Thank you

best regards,

Analog mode is used for high concentrations because once a count reaches a certain amount the detector can no longer handle that much signal intensity.  When this happens the detector automatically switches to analog mode which measures the electronic pulse signal and then uses the P/A factor to convert to a pulse signal. That is why we can have such a high dynamic range to work in.
