28 Preparing For Conductive AFM On The
Environmental Scanner
Conductive AFM works only with the gas cell body, but with any sample stage.
Prerequisites: Assemble your sample stage and gas cell body, as described in Attach cell body
and sample stage on page 82 .
Mount the sample stage onto the environmental scanner, as described in Exchan-
ging the sample stage and cell body on page 84 .
Install the gas cell cable, as described in Gas cell cable installation on page 65 .
Follow the procedure Zeroing the ORCA sample bias signal on page 190 .
Required
items: An ORCA conductive AFM cantilever holder, such as 901.767 (see Visual iden-
tification of ES cantilever holders on page 54 ).
The gas cell body 901.746 (see Gas cell on page 62 ).
The gas cell cable 448.137 (see Gas cell parts list on page 63 ).
The Electrical Sample Puck Assembly (448.140), included in the Environmental
Scanner Accessory kit.
An electrically conducting cantilever, such as the Asylum Electrilever.
1. Prepare the cantilever holder and AFM, as described in steps 1–17 of Loading the cantilever and
sample on an environmental scanner on page 205 .
2. Remove old sample.
l
Use Platypus tweezers (part # 290.165) to remove the
old sample from the sample stage.
l
Wipe the sample stage clean with a cloth or use com-
pressed air.
Any dust or grit will prevent the sample disc from
seating properly.
