Abstract
Disclosed are cell-free, stable, aqueous blood gas controls containing a proteinaceous foaming agent. The addition of foaming agent to the blood gas control permits generation of a gas impermeable foam within the head space of a sealed ampule in which the control is packaged. Upon agitation of the ampule prior to opening, the foam thus generated effectively isolates the control fluid from the ambient environment, thereby maintaining the concentration of gases dissolved within the fluid at their assigned values.
