In our latest video, discover a space-saving, GMP-compliant instrument with improved operator access

Continuing with LabLogic’s reputation for small, high-performance instruments, we are pleased to unveil the new Spec-RAM CZT gamma spectrometer. Weighing less than half the original Spec-RAM, this new benchtop instrument provides an ideal solution for identifying impurities or contaminants in gamma-emitting radiopharmaceutical samples for medical radioisotope producers, radiopharmacies, and research facilities.

Improved energy resolution with new CZT detectors

For the first time ever, LabLogic has introduced CZT detectors to its range of instruments. The Spec-RAM’s Cadmium Zinc Telluride detectors are highly sensitive to gamma rays because of the high atomic numbers of Cd and Te. This provides an energy resolution (FWHM) of <2.5 % compared to traditional scintillation detectors such as NaI(Tl). It also means the Spec-RAM CZT is a suitable alternative to High Purity Germanium (HPGe) detectors for the quality control of radiopharmaceuticals.

The Spec-RAM CZT weighs less than half the original Spec-RAM on the right.

A new cost-effective alternative to HPGe for radionuclidic purity and identity

HPGe detectors are recognised as the gold standard for determining gamma spectra, but acquiring and maintaining such a system is expensive, and its high resolution is far in excess of what is needed for radiopharmaceutical QC. In addition to costs, HPGe detectors lack compliant software, require liquid nitrogen cooling, and are large instruments that many existing laboratories cannot accommodate.

The new Spec-RAM CZT addresses every one of these issues by delivering the necessary energy resolution for gamma-emitters used in radiopharmaceutical and theranostic applications in a benchtop unit with a compact footprint measuring just 24 cm in diameter and 23 cm in height. The CZT detectors can operate in ambient room temperature as there is no Germanium to be cooled, and the instrument is controlled by our industry-standard Laura Radiopharma software, providing the necessary compliance with regulations such as FDA 21 CFR Part 11 and EU Annex 11.
