The "Test Injection" dialog appears immediately before starting the injection process
of the selected sample.
This dialog gives the user the possibility to check the transmissibility of the tip opening of the
injection needle. The defined sample volume will be injected into air. Before doing so, please
place the microscope on the x/y table in a way that you can clearly see the needle tip.
Multi Channel Systems MCS GmbH recommends up to two test injections for checking the
transmissibility of the tip opening. The additional volume for two test injections is aspirated
automatically in addition to the injection volume necessary for all injections of the respective
compound. The default test injection volume is half of the injection volume. If you have defined
different injection volumes for a respective compound, it is half of the largest injection volume.
If you do more than two test injections, the missing volume is automatically taken up during
the injection process.
Click the button "Inject" to perform the test injection the volume of which is displayed
in the up-down control window.
The "Sample" window displays important sample parameters. In the "Auto close" window
the time in seconds is counted down before this dialog is automatically closed.
Click "Continue" to start the injection process.
Click "Halt Time" if you need more time, for example, to check the tip opening by doing
test injections.
Click "Break" to stop the test injection and the general injection process, for example,
if the injection needle is broken or clogged.
The "Injection Halt" dialog appears.
