spectrometer is detected, LabQuest
enters the Full Spectrum mode. In this
mode, Intensity, Absorbance,
Fluorescence (SpectroVis Plus only), or
%Transmittance can be measured as a

o
Mode: Gas Chromatograph
– When aVernier Mini Gas Chromatograph (Mini GC)
is detected, LabQuest enters the Gas Chromatograph mode. In this mode, various
parameters are defined for the user to establish a temperature and pressure profile
adequate for the current experiment.
When the mode is first entered, a set of
default parameters is displayed. Tap the
parameter field to enter a new value, or
adjust the default value using the arrows.
These values will be reflected in the
preview of the time-dependent
temperature graph displayed at the right.
After setting the parameters, tap OK to
initiate the Mini GC warm up.

– This mode is helpful
for field work. It provides a way to
collect data referenced to two
parameters, such as the locations of your
sampling sites and the dates they were
sampled. You can collect data from an
unlimited number of sensors by
swapping the sensors in and out of
LabQuest during data collection. For
