Scintillation analysis system
A system for the combustion preparation of samples for scintillation analysis comprising a combustion tube containing a combustion catalyst, a chimney tube positioned within the combustion tube and resting on the catalyst and means for admitting a sample for combustion, oxygen gas for ignition, and an outlet means for the combustion product is described. Also, means for collecting the combustion products comprising: for H/sub 2/0 an externally cooled condenser-like system contining means for contacting a scintillation solvent with the gaseous combustion products in a cooled zone; and for CO/sub 2/ an externally cooled condenser-like system containing a helical rotatable band within the inner bore thereof for distributing a scintillation solvent along the walls thereof for countercurrent contact with the CO/sub 2/ combustion product are described.
