miniGITA Slim · Compact Radio-TLC Scanner — what the literature says.

Four real anchor citations across the workflow the compact miniGITA Slim is bought for — daily Eur.Ph. / USP <823> radiochemical-purity release for Tc-99m, F-18, Ga-68 and Lu-177 radiopharmaceuticals, sized to fit a 600 mm-deep bench. The physics of radio-TLC release doesn't care about footprint — the Slim runs the same NaI(Tl) detection chain, the same peak-fit software and the same Eur.Ph. threshold logic as its full-size sibling. Every DOI and journal reference verified.

Volume study on radio-TLC as the Tc-99m release-gate modality. Applies verbatim to the miniGITA Slim — the Slim uses the same NaI(Tl) detection chain, the same peak-fit software and the same Eur.Ph. %RCP threshold logic as the full-size Single.

The two-strip method needs no more bench space than the strip length itself — it fits the compact miniGITA Slim scan stage without workflow compromise. Modern reference method for MAG3 renal-scan release at any bench footprint.

~ 20 minTwo parallel strips deliver the full Eur.Ph. ≥ 94 % release decision for Tc-99m MAG3 within one dispensing window — modern method-development exemplar that runs identically on a compact-chassis radio-TLC scanner

The compact miniGITA Slim covers the release-gate step at any bench footprint. Theranostic preparations that require bound-species differentiation or radionuclidic-identity verification are the upgrade signal to the miniGITA Dual (radio-TLC + gamma spec on one chassis).
Method limits2024
When to pairDefines the boundary where a compact radio-TLC scanner (miniGITA Slim) should be paired with a radio-HPLC or gamma-spec check — for compact radiopharmacies, the Slim covers the release-gate step; a shared-bench radio-HPLC or an upgrade to the miniGITA Dual completes the QC chain

Validation of a radiosynthesis method and a novel QC system for [⁶⁸Ga]Ga-MAA — is TLC enough to assess radiopharmaceutical quality?
