About Us

The Green Chemistry Group was founded in 2007 as a nonprofit organization dedicated to the advancement of SFC and environmentally sustainable chemical research and development worldwide.

A Decade of SFC Conferences

We organized the first International Conference on Packed Column SFC, held a decade ago in Pittsburgh, PA

Since then, we have hosted an annual SFC conference, alternating between the U.S. and Europe, and starting in 2015 added Asia too. Each conference now attracts approximately 200 scientists, from around the globe and spanning many industries, who use – or are considering – SFC as a green technology.

These scientific conferences feature:

  • keynote addresses
  • oral and poster presentations
  • workshops
  • an exhibition of the latest technologies and applications in supercritical fluid chromatography (SFC) and supercritical fluid extraction (SFE)

Short Courses

In addition to our annual SFC conferences, the Green Chemistry Group offers SFC short courses and funds travel scholarships so select academic researchers may present their research at various scientific conferences.

Our Board

The Green Chemistry Group’s board of directors is a volunteer group of dedicated academics, industrial scientists, and leaders from sponsor organizations – those providing the equipment platforms, consumable solutions, and consulting services essential to SFC.

Our mission is to advance the use of SFC and build maximum interaction within the growing SFC community by hosting annual, international conferences.

Why SFC?

Supercritical fluids offer a convenient means to achieve solvating properties that have gas- and liquid- like characteristics without actually changing chemical structure.

By proper control of pressure and temperature, one can access a significant range of physicochemical properties without ever passing through a phase boundary. That is, a supercritical fluid is a continuously adjustable solvent.

This is the third time I’ve attended this conference, and believe it is one of the best yet
