This grid is placed into the sample holder, which is paired with the specimen stage.
The electrospray mist is attracted to the surface by applying a voltage on the sample holder.
For these samples, the sample holder is placed between two mirrors that reflect the laser beam multiple times through the sample.
The wafer sample to be treated is placed on a sample holder in a vacuum chamber.
The lipid is mixed with a matrix, such as 2,5-dihydroxybenzoic acid, and applied to a sample holder as a small spot.
The device consists of a controller box, a cooling stage, and a sample holder.
Each of the wells in the sample holder are filled with a "heavy" immersion oil.
When the pressure is sufficiently low that the boiling points of the solvents are below the temperature of the sample holder, then they will boil.
For neutron diffraction vanadium cylinders are used as sample holders.
To place the sample under investigation into the x-ray beam, a sample holder is required.
