Curve coefficient didn't correspond to the average.

Question

Hi, 
 First, I want to show how I perfomed my 1 level calibration curve. 
 
 We saw that I asked for the average when several calibration standards are used and contained the same target compound. 
 We do have the TFT in each of my 4 calibration standards. 
 We can see it at my section filtered for Cal std only. 
 
 What's weird here it's the first RF calculated is good (1083376/9.8 = 110549) but all the other ones are wrong. 
 If we take the 2nd one and did the same calculation (1110109/9.8= 113276) and the software gave 111912. 
 I don't know where this 111912 result is coming from. 
 Here my injection list that shows how I performed my calibration. 
 
 Is it because my Cal.Std are not injected one immediately after another? 
 I can see on my calibration curve that I has four point but the coefficient a given in the table is coming from the first injection only and not the average like I choose on the method process. 
 
 We can't see that the a coeffiecient on the curbe at 110549 is coming from the first injection. So it seems that the Curve calculation is not with the average of the four peaks. Why ? thank you

I try to add my sample name into the footer, but I have no results on the PDF when I tried. Can we add Sample_name field in the footer?

Hi Martin, We have updated our openlab CDS to 2.7 version so we can have the multiplier variable used in the process method. 
 
 This multiplier is filled to have all my 64 compounds. But in my sequence summary injection table, some injections has no multiplier. Do you know why?

I have another question for you Martin. You have shown me how to use "the save expression result as" to create a variable with a name. 
 
 How can I reset this variable to be able to change de name?

In this example, I want to change IPA for TFT, but my variable looks locked. 
 
 Thank you again.
