Solid Precursors

Percolation

The carrier gas percolates through a porous precursor. CeeVeeTech uses a multi point temperature sensor to measure the temperatures thoughout the porous solidified bed. 

Vapor Draw

The carrier gas removes the vapor over the surface of the bed. Layers of different temperature develop. A CeeVeeTech  multi point temperature sensor  measures the temperature field thoughout the solid bed and uses the infrastructure connected to the bubbler to deliver a precise vapor concentration.
