摘要：
Dynamic diffusion- and carburetion-type dosers are developed for preparation of verification gas-vapor mixtures (GVPs) of hydrazine. Certification of GVPs is carried out using photometric and titrimetric techniques. The operational stability of the dynamic dosers over time is studied. The diffusion-type doser allows stable dosing of hydrazine concentration over a time of 240 h, and the carburetion-type doser - over 24 h within an accuracy of 5%.
