Creating Tasks

Path: Tasks

You use tasks to automate recurring processes, such as preparing the instrument or putting it to sleep.

You create tasks using predefined task templates:

Template	Description
Make Ready	The task prepares the instrument for use. You can use it to switch on the modules, purge, and equilibrate the configured flow path. See Creating a Make Ready Task.
Standby	The task puts the instrument into sleep or into standby mode. You can use it to flush the column, fill the column, and switch off the column thermostat, the sample thermostat, and the lamp. See Creating a Standby Task.

Description

Make Ready

The task prepares the instrument for use.

You can use it to switch on the modules, purge, and equilibrate the configured flow path. See Creating a Make Ready Task.

Standby

The task puts the instrument into sleep or into standby mode.

You can use it to flush the column, fill the column, and switch off the column thermostat, the sample thermostat, and the lamp. See Creating a Standby Task.

Steps of the Make Ready Task

A Make Ready task may consist of the following four steps:

Step	Importance	Description
Purge System	Optional	The step will be executed first. It uses a high flow rate and purges the chosen channels sequentially through the sampler needle tip into waste.
Pre-Flush System	Optional	The step prepares the flow path with the specified composition.
Gradient Flush System	Optional	The step prepares the flow path with the specified composition according to the gradient timetable.
Equilibrate	Mandatory	The step is the final step of the Make Ready task. It ensures that the column and the system will be in an equilibrated state.

Steps of the Standby Task

A Standby task may consist of the following three steps:

Step	Importance	Description
System Flush	Optional	The step will be executed first. It flushes the column and the system with the specified composition.
Store Column	Optional	The step will be executed before the Standby step. It fills the column and the system with the specified storage composition.
Standby	Mandatory	The step is the final step of the Standby task. It puts the system into sleep or into standby with reduced or no pump flow. It switches off the column thermostat, the sample thermostat, and the detector as specified.

The Tasks screen lists the existing tasks in alphanumeric order and allows you to create, edit, or execute tasks.
