Column_A
Column_B

The column names are the names entered on the Components (TCC-100: Configuration) tab page in the Server Configuration program. Use the various column commands and properties to enter and check information about the columns. For more information, refer to  Dionex TC/TCC-100/TCC-3x00 Thermostatted Column Compartments: Column ID Properties.

LeftValve
ColumnA(B/C/D)_
RightValve

Sets the position of the related column switching valve to redirect the flow to column A (B, C, or D).

ColumnOven_Temp

This channel is available only if  the TemperatureSignal check box is selected in the Properties dialog box (Configuration tab page) in the Server Configuration program. If the check box is selected, Chromeleon records the temperature as a separate channel. The channel name is the name entered on the Configuration tab page in the Properties dialog box.

Click the plus sign beside the name to display the items underneath:

Delta-reports the signal slope; that is, the difference between the current value and the value one second ago. This is useful for triggers.
Signal-has the following items: Value (current signal value), UpperLimit, and LowerLimit. If the current signal value is outside these limits, a warning appears in the Audit Trail.

AcqOff-terminates data acquisition.

AcqOn-starts data acquisition.

Retention-reports the retention time of the signal (read-only).

MaxAutoStep = Maximum step rate for Auto Step Mode;
range: 0.1 - 5.1 s. Default: 5.1 s

Step-sets the step for data acquisition; range: 0.01 - 4.80 s; Auto selects the best step dynamically

Average-averages all measured values over the step interval. Default: On. Off records only the last point of each interval.

ColumnsToUse

Selects the two columns to be used alternately for injection (see also CurrentColumn and NextColumn).

Contrast

Adapts the screen contrast of the device display to your requirements.

Cooler_EquilibrationTime

The device enters the Ready state only if the difference between the current temperature and the set point temperature does not exceed the value defined under Cooler_ReadyTempDelta for the time specified here (see also ReadyTempDelta and Ready).

Cooler_ReadyTempDelta

The device enters the NotReady state if the difference between the current temperature and the set point temperature exceeds the value specified for Cooler_ReadyTempDelta. If the Cooler_ReadyTempDelta is set to None, Chromeleon does not check whether the temperature set  point deviates from the actual temperature (see also Cooler_TempReady and Cooler_EquilibrationTime).

Cooler_TempCtrl

Specifies the state of temperature control for the post-column cooler. If set to Off, post-column cooling is not performed.

Cooler_TempReady

Reports whether the temperature of the post-column cooler is within the specified limits (Ready or NotReady).

Cooler_Temperature

Reports the current temperature of the post-column cooler. The following properties are available if you open the command tree: Value (current temperature of the post-column cooler), Nominal (set temperature), UpperLimit,and LowerLimit. If the current temperature is outside these limits, a warning appears in the Audit Trail.

CurrentColumn

Selects the current column (see also ColumnsToUse, NextColumn, and ColumnX_XxxValve).

Door

Reports whether the compartment door is open or closed.

EquilibrationTime

The device enters the Ready state only if the deviation between the current temperature and the set temperature does not exceed the maximum deviation specified under ReadyTempDelta for the time specified here (see also ReadyTempDelta and Ready).

Example: If the temperature is set to 45°C, EquilibrationTime is 0.5 min, and ReadyTempDelta is 1°C, the device enters the Ready state as soon as the temperature is between 44°C and 46°C and kept in this range for 0.5 minutes.

Tips:

The smaller the value of ReadyTempDelta and the higher the value of EquilibrationTime, the longer the time required by the device to enter the Ready state, and thus to start acquisition or analysis.

Note that external conditions, such as draft or air conditioning, may also extend the waiting period or even prevent the device from entering the Ready state.

HumidityLeakSensor

Sets the sensitivity with which the sensor responds to humidity. Click the arrow in the input box and select an option from the list. Possible settings are:

Low, Standard, High: The Status LED on the front panel is red, a message appears in the Audit Trail, and a beep sounds.

Low_Silent, Standard_Silent, High_Silent: The Status LED on the front panel is red, a message appears in the Audit Trail, but no beep sounds.

Off: Deactivates humidity leak detection.

Deactivates the leak alarm.

LeakSensorState

Reports whether the sensors are ready for leak detection (Ready, NotReady, or Error).

ModelNo

Reports the model number of the device.

MsvPosition

If a column switching valve is installed and if the Internal MSV check box is selected in the Properties dialog box (Configuration tab page) for the device in the Server Configuration program, the column switching valve is switched to the desired position (A (1) or B (2)).

NextColumn

Switches the column switching valve to the next position, directing the flow through either of the alternately used columns.

NotReadyCauses

Reports the column compartment's current status.

Ready

Reports whether the device is ready to operate (Ready or NotReady; see also ReadyTempDelta, EquilibrationTime, Cooler_EquilibrationTime and Cooler_ReadyTempDelta.

ReadyTempDelta

If the current temperature deviates from the temperature set point by more than the ReadyTempDelta, the device enters the NotReady state. If the ReadyTempDelta is set to None, Chromeleon does not check whether the set point temperature deviates from the current temperature (see also Ready and EquilibrationTime).

Example: If the temperature is set to 45°C and ReadyTempDelta is set to 1°C, the device enters the Ready state as soon as the current temperature is between 44° and 46°C. If the current temperature is outside this range, the device enters the NotReady state.

Tips:

The smaller the value of ReadyTempDelta and the higher the value of EquilibrationTime, the longer the time required by the device to enter the Ready state, and thus to start acquisition or analysis.

Note that external conditions, such as draft or air conditioning, may also extend the waiting period or even prevent the device from entering the Ready state.
