Poropare™ Transfer plate
Poropare provides a novel mass spectrometry imaging without thin sectioning and matrix-spraying in mass spectrometry imaging.
Expands the possibilities of mass spectrometry imaging!
Hamamatsu developed Poropare by leveraging our unique glass-forming and thin-film deposition technologies. It features a robust porous structure with an ionization-assisting layer that simplifies sample preparation for mass spectrometry imaging.
Poropare enables ‘transfer sampling', eliminating the need for thin sectioning the samples commonly used in mass spectrometry imaging. This innovation significantly expands the range of applications.

Concept
Easy measure of a wide range of samples without thin sectioning
With Poropare, sample preparation is completed by simply pressing (transferring) the sample measurement surface onto the active surface.
Poropare eliminates the most difficult process of thin sectioning, while the ionization-assisting layer on the active surface of Poropare makes matrix-free measurements.
Step1
Cut to expose the measurement surface.
Step2
Press the sample onto Poropare.
Step3
Easy for anyone to do!
Challenging / impossible thin sectioning for some samples
Conventionally, sample preparation for mass spectrometry imaging is a complicated process. It requires a microtome machine, such as a cryostat, to cut frozen samples into thin sections. Consequently, the samples that can be measured are limited to those that can be frozen and cut into thin sections.
Step1
Cut sample into thin sections.
Step2
Apply the matrix coating.
Step3
Many steps are required....
