Commands and Tips for Third-Party Devices
Perkin Elmer Autosystem (XL) and Clarus GCs: Column

The following commands and properties are available for column control (please note that the display Filter level determines which commands and properties are displayed):

 

Property

Range/Values

Description

Flow

0 - 99.99 ml/min

(For SetPointUnit = flow)

Flow.
Nominal

Observe the restrictions for ramps.

Sets the target value for the gas flow. This does not include control: If the actual flow deviates too much from nominal flow, the column enters the NotReady state.

Flow
Value

Indicates the current gas flow (read-only).

GasType

He, N2, H2, AR/CH4, Air

Indicates the type of the used gas (as set in the Server Configuration program; read-only).

PressureCtrl

On or Off

Turns gas pressure control on or off.

Pressure

0-6.89 bar; 0-100 psig; 0-689 kPa (The unit depends on the PPC pressure unit set in the Server Configuration program.)

(For SetPointUnit = flow) Properties related to the gas pressure.

Pressure.
Nominal

Sets the nominal pressure. This does not include control: If the actual gas pressure deviates too much from the nominal pressure, the column enters the NotReady state.

Pressure.
Value

Indicates the current pressure (read-only).

Ready

Ready or NotReady

Indicates whether the carrier unit is ready. The carrier unit is ready when the set pressure (or flow or speed; set in the Server Configuration program) has been reached. (The property is read-only.)

SetPointUnit

None, psig, kPa, flow

Indicates the value of interest and the unit used for observing the gas flow (read-only). The property can be set only on the device.

 

In addition, Chromeleon supports the following commands and/or properties if the Autosystem GC includes a PPC:

 

Property

Values

Description

CapCtrlMode

On/Off

(Only for PSS and CAP inlets) Enables or disables capillary column control.

  Note:

If CapCtrlMode is set to Off, FlowCtrlMode is set to Flow and SplitCtrlMode is set to Split (also, refer to  Inlet).

Diameter

50 - 1000 µm

Specifies the diameter of the capillary column.

Flow

0 - 99.99 ml/min

Observe the restrictions for ramps (see below ˛)

Properties related to the carrier flow.

Flow.Nominal

(Only if CapCtrlMode is set to On and if FlowMode is set to Flow) Sets the nominal flow.

Flow.Value

Indicates the current flow (read-only).

FlowCtrl

On/Off

Enables or disables carrier flow.

FlowMode

for CAP, PSS :
Off, PressOvenTrack, Flow, Velocity, Pressure

 

For POC, PKD:
Off, Pressure, Flow

Sets the flow control mode.

Length

1.00 - 200.0 m

Specifies the length of the capillary column.

Pressure

0-6.89 bar; 0-100 psig; 0-689 kPa (The unit depends PPC pressure unit set in the Server Configuration program)

Observe the restrictions for ramps (see below ˛)

 

Pressure.Nominal

(Only if CapCtrlMode is set to On and if FlowMode is set to Pressure) Sets the nominal gas pressure.

Pressure.Value

Indicates the current gas pressure (read-only):

Ready

Ready/NotReady

Indicates Ready if the PPC is ready or if the specified carrier gas is not used (read-only).

Status

NotUsed, Ready, NotReady, Alarm

Indicates the current status of the PPC for the specified carrier gas.

VacuumCorrection

On/Off

(Only for PPS and CAP inlets) Turns vacuum compensation on or off.

  Note:

This property can be set only if CapCtrlMode is set to On.

Velocity

0 - 200.0 cm/s

Observe the restrictions for ramps (see below ˛)

Properties related to the carrier flow.

Velocity.Nominal

(Only if CapCtrlMode is set to On and if FlowMode is set to Velocity) Sets the nominal flow.

Velocity.Value

Indicates the current speed (read-only)

 

˛ Observe the following restrictions when you run ramps:

1. Pressure ramps: 0-6.89 bar/min or 0-99.9psig/min

2. Flow ramps: 0-99.99 ml/min˛

3. Speed ramps: 0-200.0 cm/(s·min)
