Perkin Elmer Autosystem (XL) and Clarus GCs: Inlet

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

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

Property	Range/Values	Description
FollowOven	On or Off	(Only for PPS and POC injectors) If the property is set to On, the inlet temperature follows the oven temperature (+5°C).
InletType	PKD, CAP, GSV, PSSO, PSSI, POCI, POCO	Indicates the inlet type (read-only): PKD: Packed column CAP: Capillary GSV: Gas Sampling Valve PSSO: Split/Splitless follow oven PSSI: Split/Splitless POCI: On Column POCO: On Column follow oven
Ready	Ready/NotReady	Set to Ready when the inlet heating component is ready. (If a PPC is installed, the SplitStatus setting must also be Ready.)
Status	None Ready NotReady FilamentOver Unknown	Indicates the current status of the associated heating component.
TempCtrl	On or Off	Enables or disables temperature control for the inlet.
Temperature	Without PTR: 100 - 450°C or 50 - 450°C CAP/PKD (50 - 350°C for GSV) With PTR: -99 - 500°C	Properties related to the column oven. Note: If a temperature is set, TempCtrl is automatically set to On.
Temperature. Nominal		Sets the nominal temperature. For the PSSI and POCI, this command sets a temperature ramp, instead. A maximum of two inlet temperature ramps are allowed.
Temperature. Value		Indicates the current temperature (read-only)

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

Property	Values	Description
PurgeCtrlMode	Auto, Fixed	Sets the purge flow compensation mode (level: Advanced or higher). (For more information, refer to the manual for the instrument.)
PurgeFlow	0.0 – 100.0 ml/min	Sets the split flow offset value to compensate the reduction of the split flow due to septum purge flow. (The property can be set only if PurgeCtrlMode = Fixed.)
SplitCtrlMode	Flow, Ratio	Sets the split control mode. Specifies whether the flow or the flow ratio is controlled.
SplitFlow	0 – 500 ml/min	Sets the target value for the total split flow. (The property can be set only if SplitCtrlMode = Flow.)
SplitRatio	1-6000	Sets the target value for the split ratio. (The property can be set only if SplitCtrlMode = Ratio.)
SplitStatus	NotUsed, Ready, NotReady, Alarm, Unknown	Indicates the current split status.
TotalSplitFlow	0 – 500 ml/min	Indicates the current total flow (split flow + purge flow; read-only).
