o Mode: Full Spectrum – When a spectrometer is
detected, LabQuest enters the Full Spectrum
mode. In this mode, Intensity, Absorbance,
Fluorescence, or %Transmittance can be
measured as a function of wavelength.
Detailed instructions for setting up data
collection with spectrometers are included in
each of our spectrometer experiments.
o Mode: Gas Chromatograph – When a Vernier Mini Gas Chromatograph (Mini GC) is
detected, LabQuest enters the Gas Chromatograph mode. In this mode, various
parameters are available for the user to establish a temperature and pressure profile
adequate for the current experiment.
When starting data collection, 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 to the right. After
setting the parameters, tap OK to initiate the
Mini GC warm up.
For more detailed information on the Vernier
Mini Gas Chromatograph, see

o Mode: Drop Counting – This mode is used with the Vernier Drop Counter. When using
this mode, data points are recorded every time a drop is detected by the drop counter.
For information on calibrating a drop counter, see www.vernier.com/manuals/vdc-btd
o Mode: Data Matrix – 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 more detailed information, see
