Deposited-dose determination
|
• The microbalance is capable of measuring the deposition in the module at a resolution of 10 ng/cm2.
|
1 well can be used for the microbalance (optional).
|
Gravimetric methods, using the precision balance.
|
One of the wells is designed to carry a transmission electron microscope (TEM) grid to monitor exposure. Also has an electrometer.
|
• For the 6/6 and 12/12, a built-in microbalance option is available. A microbalance sensor would occupy one compartment; therefore, the module should have at least 4 compartments in order to allow 3 replicates for exposure.
|
• For the 24/24, the purchase of a separate, standalone 12/1 CF module to use a microbalance would be needed.
|
Exposure Method
|
The VITROCELL® 6/6 is compatible with electrostatic deposition.
|
Not compatible with electrostatic deposition, but due to high deposition efficiency of NMs in the Cloud, electrostatic deposition is not needed (Cloud is equipped with a nebulizer that generates liquid aerosols).
|
Compatible with electrostatic deposition (both RFS and RFS compact).
|
Compatible with electrostatic deposition.
|
The 12/12 and 24/24 are not, but in those cases, the VITROCELL® 6/6 modules can be used with adaptors for 12 or 24-well inserts.
|
Exposure time duration
|
Maximum 6 h possible
|
Approximately 3–4 min
|
Up to 1 h reported

Ability to utilize multiple aerosol generating techniques?
|
May be used with a wide range of aerosol generators.
|
Compatible only with the aerosol generator, which is part of the delivery (vibrating mesh type for liquid aerosols).
|
May be used with a wide range of aerosol generators; One option is the Cultex® dust generator, which is a Mitchell or screw mill type.
|
May be used with a wide range of aerosol generators; Can be placed close to the workplace or aside a busy street.
