SONOPLOT MICROPLOTTER Proto, Руководство пользователя

Страница: 49 / 67

A sharp dip, followed by a spike, occurs at around 440 kHz. This is a resonance within the
dispenser. The sharper the dropoff, in the resonance, the stronger it is. Several smaller
resonances can be seen, but those are weaker than the one at around 440 kHz. The exact
resonance frequency is the frequency near the bottom of the dip where impedance is at a
minimum. After a scan, this frequency is automatically assigned to the
Dispense and Spray
values in the control window described in the Dispenser control section, because it is the
one where pumping and spraying occur most readily.
When done, the window will disappear and all dispenser functions, such as pattern printing, will
be enabled. A notification will appear indicating that the dispenser has been calibrated.
To return to this calibration dialog, either choose the menu item Dispenser | Perform
Dispenser Calibration... or the Calibrate dispenser toolbar item.
Solution well locations
The Microplotter has the ability to dispense multiple solutions when printing patterns. To do this,
the dispenser will use higher-intensity ultrasonics (the Spray settings seen earlier) to forcibly
eject fluid from the dispenser. The procedure for switching solutions consists of the dispenser
approaching a waste well (or the original solution well if you wish to conserve material), spraying
out its contents, moving to a rinse solvent well and loading solvent, moving back to the waste
well and spraying out that solvent, then moving into the well for the next solution. The solvent
rinsing process can be performed for multiple cycles before loading the next solution, to
minimize cross-contamination.
In order to know where the various solutions are located, as well as rinse solvent and waste
wells, locations are specified in the following windows.
