Automated Radionuclide Separation and Sample Preparation

High-precision syringe pumps and a valve bank deliver each reagent to the extraction column while a robotic arm handles activation, sample loading, vial washing, rinsing, and elution. An in-house online control package runs stored programs, so eight columns can be processed with one start command and minimal hands-on time.

• Eight extraction channels run in parallel on one platform.
• Corrosion-resistant platform with built-in anti-corrosion ventilation.
• Coated sampling needle resists attack and holds its shape in use.
• No air enters the column; the sorbent stays wet throughout.
• Complete loading with no sample loss; vials can be washed and reloaded.
• Multi-stage needle wash bath limits carryover between samples.
• Built-in programs and one-click operation from the control software.

One integrated unit performs sample transfer, impurity removal, water-sample acidification, carrier dosing, precipitant dosing, and precipitate collection. It is built to enrich radionuclides from large water volumes quickly enough for the enriched sample to reach the minimum detectable activity of existing radioactivity measurement instruments.

• Processes up to 50 L of water in a single batch.
• Dedicated stirring paddle mixes the batch for a complete reaction.
• Syringe pump combined with a peristaltic pump for precise reagent dosing.
• Custom cellulose filter cartridge resists pressure and prevents precipitate loss.
• Vacuum filtration separates the precipitate without settling time.
• Spray-in-place cleaning of the interior; no disassembly required.
• Corrosion-resistant construction throughout; the compact unit can be moved as a whole.

Isotope-N1 combines an automated separation and purification system, a low-background α/β counter, and control software in one modular design. Separation, purification, sample preparation, and activity measurement are handled as a single workflow, and the extraction platform can be configured for one to four parallel channels.

• Separation, purification, sample preparation, and counting in one workflow.
• Modular assembly lets the units be combined to suit the lab.
• Extraction platform runs one to four channels in parallel.
• Chemically corrosion-resistant platform design across the system.
• Closed-loop peristaltic waste handling reduces the risk of leakage.
• Pipette-needle liquid handling cuts the waste generated per run.
• Can be customized for coupling to a liquid scintillation counter.
