Go Direct® Mini GC™
Teach students chromatography with an affordable, portable gas chromatograph that detects polar and nonpolar compounds. With the easy-to-use Go Direct Mini GC, free experiments from the included e-book, and the free Vernier Instrumental Analysis™ app, students can separate, analyze, and identify substances contained in a volatile liquid or gaseous sample. Go Direct Mini GC uses Bluetooth® wireless technology or USB to connect to your device.

Go Direct Mini GC can connect via Bluetooth® wireless technology or wired via USB to your device, providing an opportunity for you to choose the solution best for your laboratory.
Developed with Seacoast Science, Go Direct Mini GC uses an efficient, software-controlled internal pump system. This design allows the Go Direct Mini GC to use room air as the carrier gas, so there is no need to purchase an external carrier gas tank or maintain a gas filtration system.
Easily incorporate gas chromatography into your curriculum using our e-book Chromatography Experiments with the Go Direct Mini GC™ available for free with your purchase.
You can also use this gas chromatograph to identify unknown compounds, monitor chemical reactions, and measure products from a distillation.
