3 Contents Perm Index BackNext What is a permeation tube? How does it work?  A permeation tube is a sealed permeable membrane containing solid, liquid or liquefiable gases that permeate through the walls of the membrane at a constant rate.  The device is maintained at a constant temperature to establish constant vapor pressure inside the device. This results in an equilibrium between liquid/solid and the vapor phase of the chemical compound. The vapor escapes through the walls of the permeable membrane at a constant rate as long as the set point temperature is maintained. A measured flow of an inert gas such as nitrogen, helium, argon etc. is passed through the permeation chamber where the device is housed to capture and mix with the vapor resulting in known volumetric concentration in ppm/ppb. By varying the dilution flow rate one is able to generate a wide range of concentrations using a single device.

5 Contents Perm Index BackNext Wafer devices  A wafer device is a type of permeation device that uses a metal reservoir and a circular TFE or FEP permeable membrane  Wafer devices have an active length of 4.6 cm and an outer diameter of 1.6 cm  Designed to allow very low permeation rates  Available with or without certification  An example of a wafer type 30T4: 30 Wall thickness, in thousandths of an inch T TFE (Permeable membrane) 4 Diameter of cap bore measured in sixteenths of an inch

6 Contents Perm Index BackNext Tubular devices  Dynacal tubular devices are primarily made out of different types of PTFE permeable membranes of varying wall thickness. They are available in active lengths of 0.5 to 20 cm long.  Each device is custom sized to generate the required mass per unit time to match the concentration range requirements of a specific application.  Typical permeation rates range from 5 ng/min to 50,000 ng/min for a single device.  Available with or without certification.

7 Contents Perm Index BackNext Diffusion vials A diffusion vial is a Pyrex reservoir attached to a Pyrex stem having a fixed bore size. The reservoir is filled with the liquid or solid material of interest. When maintained at a constant temperature, the material establishes a two phase equilibrium between the solid/liquid and gas phase where the gas diffuses through the bore of the stem. By varying the stem length and the bore size, one is able to vary the permeation rate at a set point temperature.

8 Contents Perm Index BackNext How are part numbers determined? There is a logical progression to each part number, once you understand the basic formula. Each number in the sequence represents a specific aspect of the device: for example, the type of tubing, the active length of the tube, or the chemical being used. 1XX – XXX – XXXX – XXXX – XXXX
