GC Chip Loads Activated Carbon Particles The glass gas chromatography chip from Dolomite, in collaboration with the UK's National Centre for Atmospheric Science, features a 300-µm thick layer and is fabricated with isotropic channels, which effectively replace the capillary and spindle structure found in standard GC columns. This microfluidic miniaturization enables the production of portable, robust and low-power GC systems suitable for environmental applications such as atmospheric monitoring.
The injection zone allows activated carbon particles to be loaded and held, forming a sample absorption column. Closely packed within a 100- x 100-mm microfluidic chip, the 7.5- and 1.4-m channels have an internal diameter of 320 µm to ensure efficient heat transfer. With a circular cross section, a uniform coating can be evenly applied to the inside surface of the channel, mimicking the stationary phase to aid separation.
