Flow-Count provides affordable, state-of-the-art HPLC detection for radiopharmaceutical development, monoclonal antibody labeling, environmental analysis and PET chemistry. A wide selection of detectors cover a range of activities found in metabolite studies, radiopharmaceutical purity measurements and monitoring prep HPLC.

Interchangeable Detectors give ultimate flexibility - A thin-window NaI detector is well suited to low-energy gamma such as I-125, while 1" detectors are matched to detection requirements of Tc-99m, In-111, PET isotopes,and other high-energy gamma emitters. High-energy beta emitters such as Y-90 can be monitored with a plastic scintillation detector. Very high activities, up to 1 Curie, can be monitored with a miniature PIN diode detector. It’s small size makes it easy to shield inside a hot-cell or other containment area.

Monitor Two Separates Applications Simultaneously - A scintillation detector and a PIN diode detector can be connected to the Flow-Count simultaneously. A frontpanel switch allows run-time detector selection. Remote operation of the Flow-Count up to 12’ away from the compact base unit, allows the detector you need to fit where you need it...in the hood, hot cell, or in close proximity to a UV detector on a crowded lab bench. Flow cells for all Flow-Count detectors are easily prepared and replaced by the user with standard plastic tubing. Flow cell volumes are determined by the number of loops of tubing placed in the field of view of the detector.
