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

 

Command/Property

Description

AuxValve.A

AuxValve.B

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 =
Volume to be drawn: 10 µl + flush volume

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.

Temperature

(Only for autosamplers equipped with the sample temperature control option) Sets the temperature of the sample tray.

 

 Note:

If you use the Program Wizard to create a program (see The Program Wizard), these commands are entered on the second Sampler Options page in the wizard.

  • NoWash: No wash cycle is performed (recommended for typical applications).

  • BeforeInj: Performs a wash step before drawing a sample–and thus before sample injection (needle contains no sample liquid).

  • AfterInj: Performs a wash step after sample injection.

  • Both: Combines the BeforeInj and AfterInj options.

For user-defined injection procedures, you must set wash steps explicitly.

SampleHeight

Defines how far the needle descends into the sample container for sampling (standard injections). For details, refer to  Defining the Needle Height (AS-AP).

SyncWithPump

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.)
