Permeation Tubes are available for hydrogen cyanide.
Press Release Summary:
Sep 25, 2012 - DynacalÂ® Permeation Tubes consist of inert capsules containingÂ pure chemical compound inÂ 2-phase equilibrium between its gas phase and its liquid or solid phase. AtÂ constant temperature, device emits compound through permeable portion atÂ constant rate. Accurate, stable concentrations range from PPB to high PPM. Rates can be certified using standards traceable to NIST by measuring gravimetric weight loss overÂ known period of time atÂ known temperature.

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.
Devices are typically inserted into a carrier flow to generate test atmospheres for calibrating gas analyzer systems, testing hazardous gas alarms, or conducting long-term studies of effects on materials or biological systems – in short, any situation requiring a stable concentration of a specific trace chemical.
Permeation rate data is already established for hundreds of different compounds, and rates for new compounds can be easily certified using NIST -traceable standards.
