Description

Gastec P-92-1 Permeation Tube Acetaldehyde

Gastec P-92-1 (also cataloged as P921) is a certified, standard-emission Acetaldehyde ( $\text{CH}_3\text{CHO}$ ) permeation tube engineered as a primary trace-gas generation standard. It provides a constant, reliable micro-rate release of pure acetaldehyde vapor for generating known calibration gas mixtures.

When housed inside a constant-temperature dynamic gas calibration generator (such as the Gastec PD-1B or PD-1C permeaters), it releases a factory-certified nanogram-per-minute mass flow of acetaldehyde through a fluoropolymer membrane into a controlled carrier air or nitrogen stream.
