The following screen is displayed: 

 

In the 

Acquisition Parameters

 tab, required fields like the 

Run Name

, the 

Run ID

 and the 

Acquisition length

 must be 

filled in before starting an analysis. Furthermore, if the 
system is equipped with an autosampler controlled by 
Galaxie Chromatography Data System, the 

Injection 

Volume

, the 

Vial

 position and the 

Rack

 number (if required) 

must be entered. 

Other parameters associated with each acquisition channel 
can be entered in the 

Channel X

 tab. 

3.  Click on the 

Start

 button to start the acquisition if the 

system is a single-injector system or click on the 

Next

 

button if the system is a multiple injector system. In a 
multiple injector system, the same parameters entered for 
the first injector must be entered for the other injectors 
before starting the acquisition.
