Permeation Tube emits compound at constant rate.
November 20, 2003 -
Dynacal® Permeation Tube is a small, inert capsule containing pure chemical compound in 2-phase equilibrium between its gas phase and liquid or solid phase. At constant temperature, device emits compound through its permeable portion at constant rate. Accurate, stable concentrations range from PPB to high PPM. Permeation Tube rate for existing and new compounds can be certified using standards traceable to NIST.

Dynacal® Permeation Tubes
VICI Metronics' Dynacal® Permeation Tubes, are small, inert capsules containing a pure chemical compound in a two phase equilibrium between its gas phase and its liquid or solid phase. At a constant temperature, the device emits the compound through its permeable portion at a constant rate. Accurate, stable concentrations range from PPB to high PPM.
The purpose of a calibration gas standard is to establish a reference point for the verification of an analysis. Permeation Tube rates can be certified using standards traceable to NIST by the most basic and accurate laboratory procedure - measuring the gravimetric weight loss over a known period of time at a known temperature.
Permeation rate data is already established for hundreds of different compounds, and rates for new compounds can be easily certified using NIST-traceable standards.
