 In normal/classic TCD setup, the TCD is a full bridge with 4 cells (with filaments or sensors) with both opposite cells having the same gas flow, the reference flow and the column flow. This means 4 electrical and pneumatic connections.
The MHB-principle also uses a reference and column cell (needed for maximum compensation), but only one of both! Just use it as a normal TCD but only half of it. The second 'branch' to complete the full bridge is created in electronics and software, using a proprietary design.
This means less wiring, lower power consumption, less noise pickup, fewer pneumatic connections, lower vulnerability, and what's more, only half a TCD-bridge is needed, lowering these costs with up to 50%!
