Using the Product

Installation: The Go Direct Mini GC should be used in a room that is well
ventilated to allow for normal heating and cooling. Do not use the Go Direct
Mini GC in the presence of flammable vapors.
Unpacking and Setup: Open the lid of the Mini GC carrying case. Remove the
power supply, USB cable, and the Mini GC unit from the carton. Remove the
ties holding the electrical cords. (You may wish to store the two extra septa
separately for use at a later time.)
To avoid damage to the Mini GC, place the instrument on a flat surface away
from
Excessive dust
l
Liquids or mists
l
Strong vibration
l
Strong magnetic fields, electric fields, and/or high frequencies

To operate the Mini GC, plug the low-voltage jack of the power supply into the
power socket on the side of the instrument; insert the 120 VAC plug into an
outlet. Connect the Mini GC to your platform according to the Getting Started
instructions above.
Operation of Go Direct Mini GC is controlled through Instrumental Analysis.
With this software, you can

l
Set a temperature profile, either using the default settings, or as described in
l
student lab instructions.
Set a desired pressure to run the system (maximum of 21 kPa).
l
Start and stop a run.
l
Name a run.
l
Save and export the data.
l
Integrate the peaks and determine retention time

Analytes are injected into the instrument through the injection port. Optimal
results are obtained using the supplied 1.0 μL syringe for liquid analytes.
Instructions for using syringes are provided in the Care and Maintenance
section.
Because the Go Direct Mini GC can connect via Bluetooth wireless technology,
there is also a button on the instrument itself that initiates data collection once
the Mini GC is equilibrated to the set temperature/pressure profile.
Follow these instructions to collect your first chromatogram:
1. Put on goggles and gloves.
2. Connect the Go Direct Mini GC to your platform according to the Getting
Started instructions. Note: The instrument runs a preheat cycle that sets the
temperature to 75°C when first connected to Instrumental Analysis. It will
remain at this temperature until a temperature/pressure profile is applied.
3. Set the temperature/pressure profile. Note: Below is the default
temperature/pressure profile. This is appropriate for most samples. However,
you may want to adjust these according to the student instructions in the
Chromatography Experiments with the Go Direct Mini GC™ e-book. Once
you have set the desired parameters, click or tap Apply. This initiates the
temperature/pressure profile.
4. While the Mini GC is equilibrating, follow the steps below to clean and
flush the syringe with acetone or n-hexane. Important: The glass syringe is
fragile and can be easily damaged. Be careful not to bend the needle or bend
