The Mini Gas Chromatograph (Mini GC) is a portable instrument for separating, analyzing, and identifying substances contained in a volatile liquid or gaseous sample.

Description

Use room air as the carrier gas

Developed by Seacoast Science, the Mini GC uses an efficient, software-controlled internal pump system. This design allows our Mini GC to use room air as the carrier gas.

Use Vernier’s award-winning software for column control, collection, and peak integration

With either Logger Pro or the LabQuest App, peak integration analysis and retention-time determination are built right into the software.

Measure several compounds

  • Alcohols
  • Aldehydes
  • Aromatic hydrocarbons
  • Carboxylic acids
  • Ketones
  • Esters
  • Ethers
  • Nitriles

Frequently Asked Questions

  • What type of column does the Mini GC use?

    The column is a Restek MXT-1. It is a stainless steel capillary column, 11 meters long. The column is nonpolar.

  • What is the carrier gas used by the Mini GC?

    The Mini GC uses air as the carrier gas.

  • Do you have lab experiments written for the Mini GC?

    Yes. A lab manual, which contains five experiments, is shipped with each Mini GC. The labs are also available as a free download.

  • Will the Mini GC work with a LabQuest?

    Yes. LabQuest App will need to be version 1.4 or newer. Download the latest update »

  • Which version of Logger Pro 3 runs the Mini GC?

    Version 3.8.3. If your school owns any version of Logger Pro 3, the upgrade to version 3.8.3 is free of charge. Download the latest update »
