EZChrom 3.1 Elite concentration and calibration
Posted: Thu Feb 02, 2012 9:37 am
Hello everybody,
I recently have a problem with my ESTD concentration. In fact, somebody made the calibration a couple weeks ago on a method.
I tried to use this method, wich works fine, but when I need to make my integration, I have strange concentration such as "0,001 mg/L", "0,012 mg/L", etc.
At first, I thought my components were only in my samples in very little concentrations. But I noticed that after 22 samples, I had normal concentration such as "33,456 mg/L".
I thought it was a problem in my sequence, but it is probably not: I made one sequence with a lot of samples, the integration of half of them or strange (0,001; 0,0012,...) with the others are normal.
I do not really know where the error could be, I never had this problem with my others methods. I did not change anything between samples which were probably wrong and the others. Do you have any ideas ?
And another question is: In some methods, calibrations were made, but now they do not appear in the "Review calibration", as if it was never done. It is strange because it appear in the copy if the methods... Is there any way to put the files again ? I tried but did not find how.
Sorry for my english and many thanks for your answers.
Sincerely,
Vanrob
