alarm while the Vapor Limit is set at 25, perform the following
checks on your laboratory and the instrument:
• Ensure that no open containers or spills of organic
solvent are in close proximity to the system.
• Ensure that the system is located in a well-ventilated
area.
• Ensure that there is no visible solvent leakage from the
system.
If PeakTrak continues to display the Vapor Limit alarm after
you have made these checks and corrected any problems
found, it is likely that organic vapors are present in the ambi-
ent environment of your laboratory. In this case, increase the
setting of the Vapor Limit. Settings greater than 25 are appro-
priate for laboratory environments with a somewhat elevated
background solvent vapor concentration, representing a safe
setting, but one with a reduced margin for error.
3.10.5 Set Default Tube Volumes
Click this button to open a window from which you can set the
default volume of the collection tubes. You can increase or
decrease these values to set the desired default volume
collected in each container. Just be sure you don't overflow the
containers by exceeding their capacity.
The system will automatically advance to the next tube when
this default volume is met in each tube. Keep in mind that
advanced method settings (discussed in Section 5 and the
on-line help) may override this default setting. During a run,
other factors such as automatic tube advances for detected
peaks will affect collected volume.

for the current user.
