Commands and Tips for Third-Party Devices
Merck Hitachi Pumps: Program Example

To avoid overloading the Merck pumps with too fast a sequence of commands, allow for at least 0.1 min between the individual commands. For a program example for the L6200 pump, see below:

-0.100 Pressure.LowerLimit =  0

 Pressure.UpperLimit =  400

 %A.Equate =  "%A"

 %B.Equate =  "%B"

 %C.Equate =  "%C"

;******* Detector commands: **************** 

 UV_VIS_1.Mode = UV

 UV_VIS_1.Range = 0.200

 UV_VIS_1.Response = 1.0

 UV_VIS_1.Step =  Auto

 UV_VIS_1.Average =  On

 UV_VIS_1.Wavelength = 260

0.000 UV_VIS_1.Autozero

 Flow = 1.000

 %B = 10

 %C = 0

 Inject

 UV_VIS_1.AcqOn

 Flow = 1.000

 %B = 10

 %C = 0

;The gradient starts after 0.1 minutes to avoid overload the pump with too fast a sequence of commands:

0.100  %B = 10

10.000 %B = 90

15.000 %B = 90

16.000 %B = 10

30.000 UV_VIS_1.AcqOff

 Flow = 1.000

 %B = 10

 %C = 0

 End
