Dionex Autosamplers
Dionex AS-AP Autosampler
In addition to the "standard" autosampler commands (see Dionex Autosamplers), the AS-AP Autosampler supports many additional commands and properties for controlling autosampler functions. The following commands and properties are available. (Please note that the display Filter level determines which commands and properties are displayed and that, depending on the autosampler configuration, some commands or properties may not be available.)
Auxiliary, Diverter, Fraction, Injection, and Syringe Valve Commands and Properties
Note:
For the AS-AP to control the position of an injection valve installed in another module (for example, an ICS-5000 DC), the external valve must be linked to the AS-AP. To verify or change the valve control assignment, launch the Server Configuration program and open the Properties dialog box for the module in which the valve is installed (see Adding, Configuring, or Deleting Devices). Depending on the type of module, control of the injection valve is selected on either the Inject Valve or the High Pressure Valves tab page.

This property is available only if you have specified on the Segments/Pump Link tab page that the injection command should be synchronized with the pump strokes of an ICS-3000 or ICS-5000 DP/SP (for details, see Segments/Pump Link). Usually, the setting from the Segments/Pump Link tab page is displayed by default. If you want to change the synchronization assignment for a specific application, enter the pump name in the input field.

Sampler Setup Commands and Properties
The following commands set options that remain constant throughout the sample preparation steps and the time-dependent commands of a program.
Note:
If you use the Program Wizard to create a program (see The Program Wizard), these commands are entered on the first Sampler Options page in the wizard.
Command/Property |
Description |
CapillaryOverfill |
(For Capillary Full-Loop injections only) Sets the loop overfill factor. |
CycleTime |
Sets the time between injections. To set a uniform time between injections, specify a cycle time in minutes (1 to 240). When a cycle time is specified, the autosampler delays sample injection until the specified time has elapsed since the previous injection. If the cycle time is set to 0, the time between injections is determined by the commands in the Program specified for each sample injection in a Sequence. |
FlushVolume |
(For Pull or Push mode only) Sets the flush volume to be used for the first FullLoop or PartialLoop injection. Tip: The recommended flush volume is 2 x (needle volume + bridge volume). (Also, see BridgeVolume.) |
FlushVolume2 |
(For Pull or Push mode only) Sets the flush volume to be used for additional injections from the same vial for Full-Loop or Partial-Loop injections when RinseBetweenInjections is set to No. |
InjectMode |
Injection mode (UserProg, PullFull, PullPartial, PushFull, PushPartial, PushPartial_ls, PushSimultaneous, PushConcentrate, PushSeqFull, PushSeqPartial_ls, PushSeqConcentrate, PushCap, PushSeqCap). For more information, refer to the operator's manual for the autosampler. |
LoopOverfill |
(For full-loop injections only) The product of the volume of the sample loop and the LoopOverfill factor determines the volume that is drawn in and/or transported through the sample loop before the sample is injected (in addition to the flush volume). Example: Loop volume: 5 µl, LoopOverfill: 2 = |
PartialCutVolume |
(For Partial Push mode only) The volume of sample to be "cut" (or omitted) from each side of the sample during the injection process. |
RinseBetweenReinjections |
Specifies whether a wash cycle is performed after each injection from the same sample vial or well plate. If set to Yes, a wash cycle is performed after each injection. If set to No, the wash cycle is skipped when the next injection is performed. Notes: This command lets you inject from the same sample container several times without losing sample between the injections by rinsing. A wash cycle is always performed after the last sample in a sequence. |
SmallAirBubbleVolume |
The size of the air bubble used to isolate the sample in the tubing when the syringe volume is 1 ml or less. Note: When the injection mode is PushCap or PushSeqCap, a command specifying a SmallAirBubbleVolume of 20 µl is automatically added to the program. The injection mode is selected on the Sampler Options (AS-AP) page. |

This property is available (and On) if you have specified on the Segments/Pump Link tab page that the injection command should be synchronized with the pump strokes of an ICS-3000 or ICS-5000 DP/SP (for details, see Segments/Pump Link). If you want to disable synchronization for a specific application, set the property to Off. (Also, see PumpDevice.) Note: SyncWithPump is automatically set to On when you change the PumpDevice setting. |
