HIGH THROUGHPUT SAMPLE HANDLING –
A B
TYPICAL WORK FLOW
To guarantee high sample throughput, up to 3 sample holders may be
placed on the Flexi-lock sample magazine. An optical image is acquired
of each sample holder from which the sample analysis positions are
identified during the automated ‘pump’ cycle. An acquisition method is 75mm
chosen defining all requirements for the data acquisition. A method may
define simple spectroscopy or more complex experiments such as sputter
depth profiling or angle-resolved XPS. Subsequent analysis from samples 32mm
on different sample holders can be added to the analysis queue with the
automated sample handling system exchanging the sample holder to C D
progress through the analysis queue.
