ABSTRACT:
An automatic gas flow safety device or system is provided for use with an atomic absorption spectrophotometer burner. Generally speaking, a dual function pneumatic and electrical safety device is described which provides for a cut-off of the (acetylene) gas to the burner, upon monitoring an unacceptable air flow or electrical condition, to avert possible flash-backs at the burner. The invention basically comprises a pneumatic and electrical actuated means to control the on/off flow of gas to the burner determinative on the status of the air pressure and electrical power to the system.
