Re: How to determine the purity of a peak

Thanks for your reply, but we still have some questions.
1.Where is the "Peak profile window" ? I can't find it.
2.What does "Absorbance Threshold" use for?
3. Can Peak Purity Threshold be calculated automatically ? Is it only able to be set in the method ?

Hello, We are developing DAD module on Clarity recently, but we don't know how to calculate the peak purity. After using the Agilent's control module--1200 Detectors in demo mode, we still have some questions. In peak purity view, we can see two curves. One is the peak curve, the other is the peak p...

Re: The definition of creation time and acquisition time

Dear Big Dan :D , Thank you for the answer. The issue is just what you said, in some prm files the creation time is older than or the same as the acquisition time, in a few prm files the creation time is earlier than acquisition time. I can't insert images received from our customer in this post, se...

The definition of creation time and acquisition time

Hi, The confusion is about the time defined in PRM files. In report we can see the PRM information, there are two times -- creat and acquisition. I'm not very sure the word used in English version because I use the CHS version. In my opinion, Clarity should first do the acquisition and then creat th...

About Detect Negative Peak

I would like to ask you which algorithm is used for detecting negative peak in Clarity? Is it just like the method of detecting positive peak or other especial data process method?

thank you!
