Dionex Autosamplers
Dionex UltiMate 3000 Series Autosampler Column Compartment

In addition to the standard autosampler commands (see  Dionex Autosamplers) and the UltiMate 3000 series autosampler commands (see  UltiMate 3000 Series Autosamplers), the autosampler column compartments in the UltiMate 3000 series provide additional commands for controlling column oven and temperature functions. The following commands are available (please note that the display Filter level determines which commands and properties are displayed, and that, depending on the autosampler type, some commands or properties may not be available):

 

Column Oven Commands:

Command/Property

Description

EquilibrationTime

The column compartment enters the Ready state only if the deviation between the current temperature and the set point temperature did not exceed the maximum deviation specified under ReadyTempDelta for the time specified here (see also ReadyTempDelta and Ready).

ModelNo

Reports the column compartment's model number.

Ready

Reports whether the compartment is ready to operate (Ready or NotReady; read-only; see also ReadyTempDelta and EquilibrationTime).

ReadyTempDelta

If the current temperature deviates from the temperature set point by more than the ReadyTempDelta, the column compartment enters the NotReady state. If the ReadyTempDelta is set to None, Chromeleon does not check whether the temperature set point deviates from the actual temperature (see also Ready and EquilibrationTime.

TempCtrl

Turns temperature control on or off.

Temperature

Reports the column oven's current temperature. The following commands are available: Value (current value), Nominal (nominal temperature), UpperLimit,and LowerLimit. If the current value is outside these limits, a warning appears in the Audit Trail.

 

Temperature Channel (ColumnOven_Temp) Commands:

Command/Property

Description

AcqOn/Off

Starts/terminates data acquisition.

Average

Averages all measured values over the step interval. Default: On. Off records only the last point of each interval.

Delta

Reports the signal's slope, i.e., the difference between the current value and the value one second ago. This is useful for triggers.

MaxAutoStep

Maximum step rate for Auto Step Mode; range: 0.1 - 5.1 s. Default: 5.1 s.

Retention

Reports the retention time of the signal.

Signal

The following commands are available if you open the command tree: Value (current signal value), UpperLimit, and LowerLimit. If the current signal value is outside these limits, a warning appears in the Audit Trail.

Step

Sets the step for data acquisition; range: 0.01 - 4.80 s; Auto selects the step dynamically.
