I just ran samples using very high stds, 10000ng, 25000ng, 3 of the samples were identified correctly but not quantified and I noticed that they had much lower heights than the rest of the samples. How do I go back and set the parameters so that it will identify these smaller peaks?

By "not quantified" do you mean that your Amount and Units columns in Peak Result table are missing (Millenium 32, version 3.05.01) but your peaks are integrated and identified? You have probably not defined the std amounts and units in your Processing method. Do you have a calibration curve for your std in your Processing method (usually only the last one is saved)? Check the Calibration curve window when Reviewing your Result. If this is the case and curves are missing you can always mark your Injection file and right-click and choose Alter Sample and under Edit/Amount in Component Editor you define your component and its amount. You save your method and check the calib. curves for std. If your peaks are integrated and you have calib. curve in your Processing method you should be able to quantify even your small peaks.

It may also be worth checking what you have selected as the 'minimum peak height/area' in your processing method. Peaks below this height/area will not get processed.

Is there a way to quickly identify which calibration curve was used for certain results? (Does the processing method indicate the calibration ID, etc.?)
Thanks
