new methods (see page 5) !
Product description
The Spray Head Upgrade Kit provides an improved version of the ImagePrep spray cap.
The key advantages of this new design are:
• No need to replace the piezo anymore, now only the thin perforated metal sheet
(Spray Generator II) must be replaced after about 20 sample preparations.
• Much cheaper: app. 20% of former cost per preparation only!
• Improved robustness: the new spray cap is equipped with a protection foil preventing
wetness from entering into interior parts of the spray cap during the preparation.
• Overall handling is much easier: The Spray Generator II can be changed without need
of any adjustment.
All existing ImagePrep can be upgraded by the customer himself.

Mounting the Spray Cap
Lock cap in position with thumbscrew.
Press cap fully onto spray head.
No further adjustment is necessary:
All adjustments described in chapter 6.1 of the
ImagePrep manual are not needed for the new
spray head.
Washing the Spray Cap
Whereas the metal sheet has to be cleaned after every preparation (with the ImagePrep washing
routine), the spray head needs only to be washed from time to time when massive matrix
crystallization is observed on the yellow protection film.
For washing dismount the metal sheet from the spray cap and sonicate the spray cap in alcohol
(EtOH or MeOH, NOT water) for approx. one minute. After the washing procedure carefully dry the
device with pressurized air or nitrogen. Extensively blow air into the two openings next to the clamp
in order to dry the interior parts of the spray head.
Never use water or water containing solvents for washing because water does not evaporate
completely from inside the spray cap. This would result in partial internal shortcuts and finally in a
reduced spray power.
Note: Never try to clean the spray cap when it is mounted on the spray head.
The wetness inside would immediately decrease the spray power!

Spray Power Adjustment with the new Spray Head
The global spray power adjustment is necessary every time the spray generator is replaced.
Please follow the instructions given in chapter 6.2 of the ImagePrep User Manual.
Note: Before you perform the spray power adjustment first let the new spray head spray at 100%
for a few seconds before you do the 10% adjustment!
Note: Typically offset values for the new spray head (+10% … +20%) are slightly higher than for
the old version (0 ... +10%).
Spray Generator Replacement Intervals
The metal sheet corrodes with time resulting in larger pinhole diameters and uneven spray.
In order to ensure high quality sample preparations we strongly recommend to replace the
Spray Generator II metal sheet after 20 preparations.
