Abstract
We have designed and built a versatile radiochromatogram scanner for chromatographic and electrophoretic strips of variable width and length and for chromatographic columns. The scanner’s variable speed and collimator width and the availability of digital output give it a wide dynamic range. To every extent possible, it was constructed from general laboratory equipment and surplus parts that can be found in many nuclear medicine departments. A series of validation experiments was performed to demonstrate the capabilities of the system and shows its excellent spatial resolution for such gamma emitters as Tc-99m. Quantitative results are available immediately without the need to integrate peaks by planimetry or to cut and count each activity peak.
