miniGITA Dual · Radio-TLC + Gamma Spectrometry — what the literature says.

Five real anchor citations across the workflows the miniGITA Dual is bought for — high-volume Tc-99m radiopharmaceutical release, modern two-strip TLC method development, Ga-68 DOTATATE HPLC-validated release, Lu-177 PSMA I&T theranostic release, and the honest limits of TLC-only QC that make the Dual's combined radio-TLC + gamma-spec architecture valuable. Every DOI and journal reference verified.

radionuclidic identity + purity
Radio-TLC is the release gate; radio-HPLC or gamma-spec is the identity + integrity check. The Dual's two-position architecture (TLC scanner + gamma-spec probe) delivers both release paths from one instrument, one QC session and one batch record.
Method limits · TLC vs HPLC2024
TLC alone: noHonest-limits paper — TLC alone cannot distinguish [⁶⁸Ga]Ga-HSA from the target [⁶⁸Ga]Ga-MAA aggregate. The Dual answers this by pairing radio-TLC with a fixed gamma-spec probe on the same instrument for combined radiochemical + radionuclidic release

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