High sensitivity and dynamic range

The chip is the secret behind the ultra-high sensitivity that allows the Spectro Inlets system to detect down to 10 ppm of a monolayer desorbing in a second. By design, the membrane chip is 3-4 orders of magnitude more sensitive than conventional DEMS systems for light substances.

The membrane chip was chosen to optimize the collection efficiency for those molecules that have a high volatility and that occur most often in electrochemical experiments, while lowering the uninteresting water signal. Any volatile can be measured, with a response time depending on the solubility, volatility, and stickiness of the analyte.

With the Spectro Inlets system, you can measure from 1 mA to 1 nA of continuous product formation. We have worked in collaboration with Pfeiffer Vacuum to bring you the ideal mass spectrometer for EC-MS measurements, enabling the extraordinary sensitivity that the Spectro Inlets EC-MS system guarantees.

With a 7-orders-of-magnitude dynamic range, the Spectro Inlets system can operate with gases with a 6.0 purity level. Furthermore, the entire system is constructed using VCR® metal gasket face seal components, which are rated for ultrahigh vacuum applications and are compatible with 6.0 gases.
