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
See the Specifications for the flow cells.
NOTICE For information about the chemical resistance of materials refer to
the technical literature.
Power-up check of optics, cooling fans, motors and electronics
Leak detection and safe leak handling
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.
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.
