6.5 Permeation Tube

- nitrogen dioxide - is normally a gas at room temperature and pressure, but can be liquified

at moderate pressures. The permeation tube consists of a small container of NO

liquid, with a

small window of PTFE which is permeable to NO

, see Figure 6-1. The gas slowly permeates

through the window at a rate in the nanogram/min range. If the tube is kept at constant
temperature, usually about 50

C, the device will provide a stable source of NO

gas for a year or

more. See below for permeation tube ordering information.

The NO

concentration is determined by the permeation tube specific output (ng/min @ 1 slpm

@ 50

C), the permeation tube temperature (

C) and the air flow across it (slpm). The specific

output in ng/min is a fixed function of the permeation tube and is noted on shipping container.
The ng/min units can be converted to ppb units by the following equation:
