SPE for radiotracers purification

Find the best way to purify your radiotracers

Purification is the critical step in radiotracer production

Due to the short lifetime of radiotracers, the method of purification is a key aspect in radiopharmaceutical production and long purification steps must be avoided. The method of choice must also be effective enough to ensure a high level of radiochemical purity. AFFINISEP proposes solutions based on Solid phase extraction (SPE).


Benefits of Solid-Phase Extraction (SPE)

- Rapid and simple radiotracer purification: no need for a preparative HPLC thanks to our SPE cartridges

- Increased reliability of radiotracer production: reduction of manual handling steps

- Improved radiotracer purity: no cross contamination thanks to single use cartridges

- Compatible with radiofluoration automates
