3.5.1 Sample Plates Types and Applications
The Voyager Instrument Control software supports several
types of reusable and disposable plates. See Table 3-2 for the
applications of different sample plates.

Sample Plate Type Applications/Benefits
Welled Sample Plates
Gold • GPC-MALDI or HPLC fractions when high
concentration of organic solvent provides no
surface tension.
• Polymer analysis using highly volatile solvents.
• Easier automated acquisition, specifically for
search pattern (.SP) file creation. Ensures correct
sample placement needed for running in
Automatic Control mode.
Flat Sample Plates (Laser Etched)
Stainless steel • Increased mass accuracy, allows close external
calibration procedures.
• Etched circles ensure correct sample placement
needed for running in Automatic Control mode.
• Crystallization, particularly with DHB, DHBs, and
3-HPA, is more defined on stainless steel and
easier to observe on the video monitor.
