The Q-Sense ALD (Atomic Layer Deposition) Holder is designed to enable QCM-D measurements in vacuum or gas phase.
The ALD Holder is open on both sides of the sensor to prevent uneven pressure changes over the two sensor faces, hence enabling measurements at both low and high ambient pressures. Cables are provided to connect the ALD Holder to the measurement chamber. The measurement signal is transferred via two separate cables through the chamber wall to the QCM-D electronics unit. The ALD holder is suited for the electronics unit of the Q-Sense Explorer (previously Q-Sense E1), but is also compatible with the electronics unit of the Q-Sense Analyzer (previously Q-Sense E4) and the Q-Sense Pro (previously Q-Sense Omega Auto).
