Section 2 Preparation
Time Zone – Select your time zone from the drop-down list.
This allows the factory set time to be updated to correspond to
your time zone. This also allows the system to adjust the system
time for seasonal time changes (such as daylight savings time in
the United States). If the date of this time change is changed by
the local government, the system may not be correct based on the
changed effective date.
Speaker Volume – Used along with red lights in the fraction
area (on some systems) to alert the user to items such as col-
lection rack fill, solvent low, and serious errors. The alert sounds
also occur to alert the user to when the run is complete or equili-
bration is complete for liquid or solid (pause) loading techniques.
Settings: Very High, High, Medium, Low.

PurIon Delay – Configuration for the connection tubing
included with the PurIon. If your installation has a PurIon Mass
Detector and no ELSD detector, this value is 11.0 mL. If the
system also has an ELSD detector included, this value is 4 mL.
Automatic Column Purchase – E n a b l e s a f l a s h c o l u m n
supply agreement that must be purchased separately from the
system. This allows us to supply columns as needed without need
for inventory management at the customer's site.
2.13 Vapor Limit (if
The CombiFlash NextGen system has an internal vapor sensor
that detects vapors present inside the system. This sensor mon-
equipped)
itors the system for premature pump seal failure or leaks of the
internal plumbing connections. Fluid vapors external to the
system may be detected when ambient air is drawn into the
system by the cooling fan. When the vapor level limit is exceeded,
the system will stop the pumps to minimize a hazardous con-
dition.
Currently, Teledyne ISCO ships all systems with this vapor limit
feature. The default setting of High sensitivity is recommended
because the response of the sensor to vapors from other solvents
may vary.
Sensitivity settings and the approximate percentage relative to
the lower explosive limit (LEL) of hexane are provided in the
table below:
