THE N E W PACKARD TRI-CARB® FLOW M O N I T O R / FLOW DETECTOR SYSTEMS . . . add another dimension to liquid and gas chromatography.
With them,
the research scientist can obtain an immediate radioassay of components in an effluent stream, without the need for time consuming analysis of individual samples.

measure 2 0 0 dpm in a single peak, when used with an amino acid analyzer.
High counting efficiencies
14
(25-30% for C , 1-2% for H3) and low backgrounds (20-25 cpm) make this method ideally suited for counting weak beta emitters such as H3 and C14. For more energetic isotopes such as
P32 or CI36, efficien-
cies are even higher and backgrounds lower.
