Detection and Integration
Monolithic integration of micromachined components for GC requires a holistic view with attention paid to the components for their individual performance. In our current strategy of integrating separation columns and detectors, their process flows are maximally decoupled by moving them onto Silicon and Pyrex respectively and bonding them. This allows the individual development and study of the standalone components, such as thiol coated separation columns in silicon, thermal conductivity detectors on pyrex.
