Using Chemistry Instruments with LabQuest

Update Your LabQuest

Our LabQuest interfaces have a built-in application for data-collection and analysis. Please update your LabQuest to the latest version for optimal sensor compatibility and functionality.

Connect Your Chemistry Instrument Using USB

1. If you are using a Mini GC, connect it to AC power, and turn the instrument on.
2. Ensure your LabQuest is charged or connected to AC power.
3. Turn on LabQuest and choose New from the File menu.
4. Connect your instrument to the USB port on LabQuest. The app will identify the instrument and load a default data-collection setup.
5. If you are using a Go Direct Mini GC, you can change the default sensor channels.
   1. Tap the sensor meter and select Sensor Channels...
   2. Select the sensor channels you want to use.
   3. Tap OK.
6. You are ready to continue your experiment.

Connect Your Chemistry Instrument Using Bluetooth®

1. Ensure your chemistry instrument is charged or connected to a power source.
2. Turn the instrument on (the Bluetooth LED will flash red).
3. Ensure your LabQuest is charged or connected to AC power.
4. Turn on LabQuest and choose New from the File menu.
5. Choose Wireless Device Setup > Go Direct… from the Sensors menu.
6. Choose your instrument from the list of discovered devices and tap OK.
   • The app will identify the instrument and load a default data-collection setup.
   • The Bluetooth LED on the sensor will blink green when it is successfully connected.
7. If you are using a Go Direct Mini GC, you can change the default sensor channels.
   1. Tap the sensor meter and select Sensor Channels...
   2. Select the sensor channels you want to use.
   3. Tap OK.
8. You are ready to continue your experiment.

Data Share Your Sensor Data Using Wi-Fi and LabQuest 3

Data Sharing lets you stream data collected on a LabQuest 3 (or LabQuest 2) to multiple devices that are running Graphical Analysis. Your LabQuest must be on the same Wi-Fi network as your devices. Note: This option does not work for Graphical Analysis run in a browser.

LabQuest cannot receive data via Data Sharing, it can only act as a Data Sharing source.

1. Ensure your LabQuest is charged or connected to AC power.
2. Turn on LabQuest and choose New from the File menu.
3. Connect the sensor to your LabQuest using a USB or Bluetooth connection .
4. Enable Data Sharing on LabQuest.
5. Launch Graphical Analysis on the device you wish to Data Share with.
6. Click or tap .
7. Choose your LabQuest from the list of discovered Data Sharing sources.
   • Graphical Analysis will connect to your LabQuest.
   • If your version of Graphical Analysis has the Pro features unlocked, select the Local data sharing option to see the list of devices.
   • If your LabQuest does not show up in the list, click or tap  and enter the IP address of the LabQuest.
   • If you are using a Chromebook or running Graphical Analysis from a browser, open a new browser window and enter the IP address of the LabQuest to share the data with your device.
8. You are ready to continue your experiment by collecting data using the LabQuest. (The connected devices will also receive the data.)
