Section 2 Preparation

2-31

• Ensure that no open containers or spills of organic

solvent are in close proximity to the Torrent.

• Ensure that the Torrent is located in a well-ventilated

area.

• Ensure that there is no visible solvent leakage from the

Torrent.

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 12 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.

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. Be

sure you do not overflow the containers by exceeding their

capacity.

The system will automatically advance to the next tube (or

container when using the Fractionation Valve) when this

default volume is met in each tube. Keep in mind that

advanced method settings (discussed in Section 3 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.
