Analog output
2 analog outputs via optional plug-in expansion board to output absorption
channels
Resolution: 20 bit
Maximum data rate: 50 Hz
Outputs can be configured via software (output voltage range 0 to 1 V or
0 to 10 V, sensitivity and offset)
Control
Chromeleon 7
The device can be operated also with other data systems. For details,
contact the Thermo Fisher Scientific sales organization.
Keypad with 3 buttons for performing certain functions directly from the
device
Materials in the flow path
See the
Specifications
for the flow cells.
NOTICE
For information about the chemical resistance of materials refer to
the technical literature.
Safety features
Power-up check of optics, cooling fans, motors and electronics
Leak detection and safe leak handling
Good Laboratory Practice (GLP)
features
Predictive Performance functions for scheduling maintenance procedures
based on the actual operating and usage conditions of the device. This
includes monitoring of lamp age, and lamp ignitions for UV and VIS lamp.
All system parameters are logged in the Chromeleon Audit Trail.
Temperature reference conditions for noise, drift and linearity specifications
For drift tests, ASTM requires that temperature changes stay below 2 °C/
hour over a period of one hour. The drift specification above is based on
these conditions. Larger changes in the ambient temperature will result
in a larger drift.
