Redefining the GC

The 200 Series GC was originally created out of an idea to be able to offer a compact, simple to operate, afforable gas chromatograph for education that didn’t compromise on analytical performance.  To achieve these requirements we knew we would have have to take a different approach from other GC manufacturers and radically rethink what a GC could be.

“When we designed the 200 Series GC we questioned everything.  Why does a GC need to be so big, use so much power and cost so much ? We wanted to make an instrument that made Gas Chromatography more accessible.”

The Heat Exchanger

The Heart of the 200 Series GC is its unique flow through oven and heat exchanger system. In most conventional GC’s ambient air is drawn into the oven  it then passes through a heater to heatthe air and ultimatly the oven.  Whilst an effective and proven trechnique the energy and heaters required to heat ambient air to temperatures used in GC are considerable.

In the 200 Series GC, we use a unique heat exchanger system. This allows air to pass into the GC through one side of the heat exchanger, through a heater and into the oven.  The Oven is specifically designed so that incoming air circles the oven creating a consistant temperature profile before exiting back out via a heat exchanger.  As the hot air from the oven passes back out via the heat exchanger it transfers much of its heat to the incoming air passing through on the other side. This retention of heat within the GC makes the heating process many times more efficent meaning less power is required and consequently smaller heaters can be used.

When it comes to cooling down the Heat Exchanger can be bypassed allowing ambient aire to pass through the oven to rapidly cool.

What do you actually use ?

Whilst it may be tempting to chase specifications and try to offer the biggest numbers and the most features, at Ellutia we belive the best products are those with clarity and focus on what they want to achieve.  To achieve the original goals of being smaller, more energy effiecent and more affordable we knew we would need to consider what a typical GC user actually needs. 

  • Do they need an oven that can heat up to temperatures hotter thanthe majority of columns can withstand ?  – No.
  • Do they really need two channels or are most users only running one sample at a time ? – No.
  • Do Column ovens need to be big square boxes or are we just wasting energy heating extra space ? – No.
  • What features are required to ensure the quality of the chromatography still matches larger conventional instrument ?

Compact Size

The smaller column oven to minimise dead volume, only having a single injector and detector, a column oven temperature limit of 300˚C (A lower upper temperature brings a number of upsides you don’t require as much insulation, you can use smaller heaters which only require smaller power supplies). All of these allowed us to dramatically reduce the size and weight of the 200 Series GC.
