Hi Lstephan
The autosampler moves the sample backwards and forwards (draw and eject) inside the sample loop.
In the past, where I wanted better mixing than this, I would eject the sample into an empty low volume vial and draw and eject in that location…
Hi Daniel
The user manual for the Vialsamplers (I think that's what I'm looking at in your photo) has three options for this:
5068-0215 - Stator, Injection Valve, 600 bar/800 bar
or
5068-0216 - Stator, Injection Valve, 1300 bar
I'm guessing…

Hi, could you please check if you have "Method Development" option activated in HS method settings? If you do, please set it to "None", save the method and try if it works. Thanks.
Hello sao.uch ,
There is not a way to do something like a spectral library match with chromatograms. If there are specific peaks you are interested in you could set up a simple quant method and define one run as your standard with a concentration of…
