Barber-Colman Model 5190 Radioactiv ity Monitoring System a n d Series 5000 Selecta-System provide t h e ultimate in continuous radioactivity monitoring for either 14 C or 3 H labelled materials. Model 5190 includes a combustion fur nace, proportional counter a n d ratemeter. I n operation, the G / C column effluent is split with p a r t of t h e sample going t o t h e mass detector a n d t h e rest to t h e R.A.M. system. T h e sample is immedi ately burned t o C 0 2 and H z O . T h e H 2 0 is then reduced t o H2. T h e radioactive CO2 a n d H 2 a r e counted a t ambient temperature. Series 5000 Selecta-System with allglass columns a n d direct on-column injection is t h e basic G / C unit used with t h e R . A . M . system. Series 5000 instruments a r e t h e product of Barber Colman's m a n y years of experience in the biomedical field and were designed specifically for biomedical applications.
