Patent ID: 8664617

Claim:
A multi-stream optical interrogation flow cell for a radiopharmaceutical comprising: a first flow cell body defining a first elongate fluid flowpath therethrough for conducting the radiopharmaceutical therethrough, said first flow cell body further defining: an elongate optical channel extending therethrough; a first and second aligned UV transparent optical guides positioned within said optical channel; and a first interrogation passageway of said fluid flowpath extending between said first and second optical guides such that the radiopharmaceutical flows in between the first and second optical guide; a second flow cell body defining a second elongate fluid flowpath therethrough for conducting the radiopharmaceutical therethrough, said second flow cell body further defining: an elongate optical channel extending therethrough; a first and second aligned UV transparent optical guides positioned within said optical channel; and a first interrogation passageway of said fluid flowpath extending between said first and second optical guides such that the radiopharmaceutical flows in between the first and second optical guide wherein said first and second optical channels are optically aligned so that a single interrogation beam is able to extend through both said optical channels; A first optical port and a second optical port, wherein said first optical guide seals said first optical port and said second optical guide seals said second optical port; A fluid inlet port and a fluid entry segment extending in fluid communication between said fluid inlet port and said interrogation passageway; A fluid exit port and a fluid exit segment extending in fluid communication between said fluid exit port and said interrogation passageway; and an opaque spacer positioned between said first and second flow cell body, wherein said spacer comprises a planar body defining an aperture therethrough in registry with said second optical port of said first flow cell body and said first optical port of said second flow cell body.
