Abstract
An explosion-proof apparatus includes a pressure resistant explosion-proof case, heater, manifold, and analyzer unit. The heater is disposed in the pressure resistant explosion-proof case. The manifold is heated by the heater in the pressure resistant explosion-proof case and supplies heat from the heater to an outside of the pressure resistant explosion-proof case by heat conduction. The analyzer unit is disposed outside the pressure resistant explosion-proof case in contact with the manifold, and is heated by heat supplied from the manifold.
Claims9
A gas chromatograph comprising:
- a pressure resistant explosion-proof case;
- heating means disposed in said pressure resistant explosion-proof case;
- a heat conduction member heated by said heating means in said pressure resistant explosion-proof case and adapted to supply heat front said heating means to an outside of said pressure resistant explosion-proof case by heat conduction;
- and
- an analyzer unit disposed outside said pressure resistant explosion-proof case in contact with said heat conduction member and heated by heat supplied from said heat conduction member.

A gas chromatograph comprising:
- a pressure resistant explosion-proof case comprised of at least a housing with an opening and a manifold attached to said opening of said housing, said manifold having a plurality of gas flow paths;
- art analyzer unit having a flow path selector valve and adapted to come into surface contact with an outer surface of said manifold to switch flow paths of an introduced gas, and a column for separating a component of the introduced gas;
- heating means, disposed in said pressure resistant explosion-proof case, for heating an inner surface of said manifold, thereby supplying heat to said analyzer unit through said manifold;
- and
- temperature keeping means, disposed outside said pressure resistant explosion-proof case, wherein said analyzer unit is kept a constant temperature by said temperature keeping means.
