Qmix λ Hardware Manual

Operation
The Qmix λ modules allow performing a spectral analysis of fluids within a flow measuring cell of
variable length.
The installation and handling of the spectrometer are described in the related spectrometer manual.
This can be found on the supplied CD. Read this manual and follow the instructions it gives, before
connecting the module to your system.
The two Qmix λ modules differ in the used spectrometer and in the light source. The smaller module,
depending on the configuration, covers a wavelength range of 350 to 1100nm. It provides an integrated
LED light source, which can be adapted to the required wavelength range. An adapter with SMA 905
connector is also available.
The larger module can be adapted for best performance in a wavelength range from 200 to 1100nm.
Any external light source can be connected via an SMA 905 connector.
To compensate the influence of differing optical density, both modules incorporate a flow measuring
cell of variable length. The functionality of the flow measuring cell is shown in the following cross
section drawing. The intermediate piece which is slightly darker in the picture can be exchanged and is
available in three different lengths. This results in measurement sections of 8, 16 and 32mm length.
