4Use
4.1 General description of the device
The Qmix λmodules are a part of the Qmix micro reaction and analysis system. They allow the spectral
analysis of fluids in flow.
4.2 Intended use
The Qmix λmodules serve the spectral analysis of fluids in flow. They are intended only to be used in a
Qmix micro reaction system from CETONI GmbH. The application is usually carried out in laboratory-
like rooms.
4.3 Reasonably foreseeable faulty application
A use for applications distinct from the intended purpose can lead to dangerous situations and is to be
omitted.
CAUTION. The unit must not be used as a medical device or for medical purposes!
4.4 Safety advice
For the safe operation of the Qmix λmodules it is necessary to observe the safety measures from the
general section of the manual for the Qmix micro reaction system. Take into account particularly the
remarks regarding the European Pressure Equipment Directive 2014/68/EU.
IMPORTANT. Please read this manual, the general part for the Qmix system, as well as
the related software manual carefully and completely before putting your Qmix λmodule
into operation.
When using an external light source, please read the associated manual carefully and
completely before putting the light source into operation. Pay particular attention to the
safety instructions contained therein.

Qmix λHardware Manual 11
5Transportation and storage
The individual modules must not be lifted or transported plugged-together. Transportation of plugged-
together devices is only allowed in the original packaging.
Use the original packaging for transportation or shipping of the module.
Concerning the storage conditions, please observe the data from chapter “Technical data”.
CAUTION. Risk of damaging the device. Do not transport the modules plugged-
together.
CAUTION. Transportation, storage or operation of the modules below 0°C with water
in the fluid passages may cause damage to the module.

6Operation
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.

Qmix λHardware Manual 13
CAUTION. Check chemical resistance of the wetted parts against the used chemicals
before using the device.
CAUTION. The flow measuring cell is suitable for a maximum operating pressure of
10 bar. Make sure that the tubing, you want to use, is also suitable for the expected
pressure.
CAUTION. Depending on the configuration of the internal or an external light source
optical radiation may leak, that can cause eye and skin damage. Note the safety
information concerning wavelength and optical power. When using an external light
source read the associated manual of the manufacturer and follow the safety instructions
therein.
6.1 (Dis)Assembly of the measuring cell
Both Qmix λ modules have a holder for the measuring cell. The only functional difference is the
presence of spring contacts on the small which serve to power the LED light source.
The measuring cell consists of the same parts on both Qmix λ modules - two connection pieces and an
intermediate piece. The assembly of the measuring cell on the devices will be described below.

Place the window followed by the O-ring in the central recess of one of the connection pieces. If the
window is provided with an anti-reflective coating on one side, the window has to be placed with this
side first.
Attach the connection piece to the holder on the module with two M2.5x8 screws using a 2 mm Allen
key. It may be helpful to hold the module upright, lest the window and the O-ring fall out.
At the small module, the spring contacts protrude through the connection piece.

The intermediate piece is mounted next. The shortest intermediate piece is simply inserted into the
recess of the connection piece ①. The two longer intermediate pieces are attached with the
corresponding screws (M2.5x10 or M2.5x25) using a 2mm Allen key ②.
Make sure that O-Rings are mounted in the recesses of the intermediate piece on both sides. The PTFE
tubing can be used optionally.
Finally the second connection piece is mounted. When the shortest intermediate piece is used, the final
connection piece is screw mounted directly on the existing connection piece ①. When one of the
longer intermediate pieces is used, the final connection piece is screw mounted to this ②. Use the
corresponding M2.5x10 screws therefore.

6.2 Fluidic connection
The fluidic connection of the measuring cell is achieved with 1/16” tubing and coned 10-32 UNF fittings
(for instance IDEX F-120).
The direction of flow through the measuring cell does not matter. So it is your decision which of the
ports you would like to be in- or outlet.
6.3 Light source
The small module provides an integrated LED light source. The brightness of the LED can be adjusted to
your needs with the dial on the device. An adapter with SMA 905 connector for use of external light
sources is available optionally.

The larger module is equipped with the SMA 905 connector by default. Insert the fiber of the external
light source into the connector and tighten the union nut.
6.4 Changing the light source (small module)
You can replace the LED attachment, for example in order to change the wavelength of the emitted
light. To do this, remove the two marked screws with a phillips screwdriver and then simply exchange
the LED attachment. Please do not remove the smaller screw in the centre.
If you want to mount the SMA 905 adapter instead of the LED light source, remove the two screws with
a 2 mm Allen key and then pull out the mounting plate. Make sure that the window and the O-ring
remain in the central recess of the connection piece. Now you can plug in the SMA 905 adapter and
fasten it with the accompanying Phillips screws.

7Maintenance and care
If used in accordance with intended purpose, the device is maintenance-free. Should there be a failure
despite this, which you cannot eliminate yourself, or which requires opening the device, please contact
CETONI GmbH to coordinate further actions. The device may only be opened by CETONI GmbH or
thereby authorized service staff. Otherwise the warranty and guarantee claims are void.
Software-related troubles are dealt with in the Software Manual.
For cleaning it please rub the surface gently with a soft, damp cloth. The cloth must not be wet, so that
no fluency can trickle into the device. In case of a heavier soiling you can also use a little bit of
detergent or alcohol.
