Command/Property

Range/Value

Description

AccessTray

Moves the XYZ arm to the back of the tray compartment to allow removal of trays from or placing trays into the tray compartment.

AutoBottomFinder

On, Off

Turns active vial bottom sensing on or off if the Sense Bottom option in the Chromeleon Server Configuration is set to AUTO. Note that bottom sensing is not available for reservoir vials (RV1 - RV4).

CalibrateCustomBottomDistance

Valid position range depends on tray type

This command can be used to calibrate the distance that the needle has to travel to reach the bottom of the vial or well, for example, when using custom vials or micro titer plates. First, enter a valid position, and then click Execute. As an alternative, enter the distance directly under CustomBottomDistance.

ChangeNeedle

Moves the XYZ arm to the needle replacement position.

ChangeSyringe

Moves the syringe to the position for syringe removal.

CustomBottomDistance

Allows setting the distance between the bottom of the vial and the needle tip manually, for example, for custom vials or micro titer plates. Also, see CalibrateCustomBottomDistance.

DeadVolume

The dead volume is the internal volume of the transfer tubing, which connects the injection port of the autosampler with the injection valve. The label on the tubing shows the volume. The value entered in the Server Configuration (Configuration tab page) must match the value specified on the label (read-only).

Home

Moves the XYZ arm to its home position.

HomeSyringe

Moves the syringe to its home position.

Inject

Injects the sample.

InjectMode

Full, Partial, No_Waste

Specifies the injection mode.

InjectSpeed

Range depends on syringe type

Sets the speed at which the syringe aspirates and dispenses the sample. The available range depends on the installed syringe type.

LoopLoadingSpeed

Range depends on syringe type

Sets the speed at which the sample is loaded onto a column or trap (only in No_Waste inject mode).

LoopVolume

Maximum value depends on syringe type

Reports the value for the loop volume entered in the Server Configuration (Configuration tab page). The value should match the volume of the installed sample loop (read-only).

MoveNeedle

Valid position range depends on tray type

Moves the needle to the specified vial or well position.

PartialInjectLowVolume

No, Yes

Allows low volume injections (only in Partial inject mode).

Position

Valid position range depends on tray type

Indicates the sample position on the sample tray. The available range depends on the tray type. For more information, see  Thermo Scientific Accela/Surveyor Plus Autosampler: Sample Positions.

PostInjectValveSwitchTime

Off, 0.1 - 999.0 min

Specifies the time after which the injection valve switches to the Load (fill) position, following an injection. The default setting Off leaves the valve in the inject position during the entire run. If you enter a value, remember to leave the valve "open" long enough to backflush your sample out of the sample loop. Example: For a flow rate of 1 mL/min and a 100 µL sample loop, it will take a minimum of 0.1 minutes to backflush the sample out of the loop.

SampleHeight

0.1 - 18.0 mm

Determines how far the needle descends into the sample vial.

Status

Reports the current instrument status (read-only).

SyringeType

Reports the syringe type entered in the Server Configuration (Configuration tab page). The value should match the installed syringe type (read-only).

TrayType

Reports the tray type entered in the Server Configuration (Configuration tab page). The value should match the installed tray type (read-only).

Volume

Sets the volume to be injected.

Command/Property

Range/Value

Description

ColumnOvenAvailable

Yes, No

Indicates whether a Peltier column oven is installed (read-only).

ColumnOvenTempCtrl

On, Off

Turns column temperature control on or off. If the property is set to ON and the Wait for Temperature Ready check box is selected in the Server Configuration program, the sampler waits until the column oven has reached the target temperature before starting the injection.

ColumnOvenReady

Ready, NotReady

Indicates whether the column oven has reached the target temperature (read-only).

ColumnOvenTemp

Temperature of the column oven.

*.Nominal

5 - 95 °C,  Off

Sets the target temperature of the column oven.

*.Value

5 - 95 °C

Current temperature of the column oven (read-only).

DoorOpen

Closed, Open

If the Verify Door is Closed check box is selected in the Server Configuration program, the sampler monitors whether the tray compartment door is closed and will not execute a command while the door is open. The property reports the door status (read-only).

TrayOvenAvailable

Yes, No

Indicates if a tray temperature control unit is installed (read-only).

TrayOvenTempCtrl

On, Off

Turns tray oven  temperature control on or off.  If this property is set to ON and the Wait for Temperature Ready check box is selected in the Server Configuration program, the sampler waits until the tray oven has reached the target temperature before starting the injection.

TrayOvenReady

Ready, NotReady

Indicates whether the tray oven has reached the target temperature (read-only).

TrayOvenReady

Tray oven temperature.

*.Nominal

0 - 60 °C, Off

Sets the target temperature of the tray oven.

*.Value

0 - 60 °C

Shows the current temperature of tray oven (read-only).
