Permeation tubes 

KIN-TEK Trace Source™ permeation tubes use a mixture of reagent-grade nitric and sulfuric acids as the analyte source. The sulfuric acid binds the water, reducing water emission to negligible levels. Emission of the sulfuric acid is extremely low compared to that of nitric acid, so the emission is primarily nitric acid. Formation of nitrogen oxides in the vapor is minimized by dynamically blending the emission to form trace concentration mixtures that are then used immediately. Tubes are available for concentrations from low parts per billion to about 10 ppm in 1-L/min dilution flow. KIN-TEK Laboratories Inc. (La Marque, Texas).
