XFlash
®
detectors. Bruker’s XFlash
®
detectors are maintenance-free. There is no excess wear
out whatsoever by permanently powering the detector; nonetheless detectors for light element
analysis may exhibit slight parameter changes after very long periods (several days) of
continuous operation.
From time to time the cooling system needs to be switched off for some hours to regenerate the
crystal of the detector. Ideally, an XFlash
®
detector should be running in standby mode during
work-free shifts or on weekends.
Caution!
After complete shut-down of the XFlash
®
detector, an extended warm-up period
and/ or recalibration may be necessary for high precision measurements.
Standby. Standby mode for the thermoelectrically cooled detector can be chosen between work
sessions in order to save energy and regenerate the crystal while maintaining reduced time to
return to stable operation (seconds). Standby mode is also provided for the spectrometer
electronics. Standby mode can be entered via command from the M4 TORNADO program
window (see section 6.2.2.1) or by confirming the corresponding option when terminating a work
session.
Cooling mode. A mode selection for the detector cooling is provided for XFlash® detectors.
Maximum cooling will provide the optimum energy resolution. Thermostat mode will reduce
possible changes due to varying environment temperature. Though these changes are normally
negligible, thermostat mode is the proposed setting with most QUANTAX applications. Please
check the detector manual, to decide which of the above options is the most suitable for your
purpose.
Detector window. The X-ray detectors can be equipped with a beryllium window (detection range
starting from sodium) or a light element window. Both kinds of windows are extremely thin, fragile,
and contact sensitive. In general, cleaning of the windows is neither necessary nor permissible. If
unavoidable, contact customer support or your local supplier for assistance.
A broken window caused by any user interaction impairs warranty and can result in a total loss of
the X-ray detector. Additionally, a broken beryllium window represents a substantial health risk
(see section 2.3).
5.4.1.2 Software and data handling
Backing up data. Even state-of-art, complex and versatile software systems cannot be designed
to completely exclude the possibility of damage or impairment by improper operation and/or
misuse. The safety measures provided by the operating system can only moderate this.
Additionally no existing computer system is actually immune against potential hardware or
software errors. Appropriate backing-up of all relevant data is strongly recommended. No
warranty can be accepted in case of data loss by whatsoever reasons.
Maintaining system integrity. The QUANTAX system is installed on special selected and
configured computers. Any change of the system configuration, user status, access rights, or else
can impair system integrity. Also new applications, especially multi-media, internet, and game
software can interfere with QUANTAX. The internal client-server architecture of QUANTAX
depends on Windows
®
communication services that may be adversely modified by subsequent
installations.
