Tailin Biotech Auto-Nuclear Pharmacy QC Analysis Workstation

Overview

The Tailin Biotech Auto-Nuclear Pharmacy QC Analysis Workstation is a purpose-built, integrated analytical platform engineered for quality control testing of radiopharmaceuticals under controlled radioactive environments. Designed in strict alignment with current Good Manufacturing Practice (cGMP) and Good Laboratory Practice (GLP) frameworks, the system implements automated sample handling, dose calibration, radiochemical purity (RCP) assessment, and radionuclidic identity verification—enabling full compliance with regulatory expectations from the U.S. FDA, European Pharmacopoeia (Ph. Eur.), and Chinese Pharmacopoeia (ChP) Chapter 9301. Its operational architecture leverages shielded robotic manipulation, gamma-compatible detectors, and programmable liquid handling modules to perform sequential assays—including instant thin-layer chromatography (iTLC), high-performance liquid chromatography (HPLC), and gamma spectrometry—without manual intervention inside hot cells or ventilated hoods. This eliminates operator radiation exposure while preserving assay integrity across batch release, stability studies, and clinical trial support.

Key Features

• Full automation of radiopharmaceutical QC workflows: sample vial loading, dilution, filtration, chromatographic separation, detector positioning, and data acquisition
• Integrated dual-detection capability: simultaneous gamma spectroscopy (with NaI(Tl) or HPGe detector options) and UV-Vis absorbance for co-elution confirmation
• Hot-cell–optimized footprint (W × D × H ≤ 600 × 750 × 1200 mm) enabling seamless integration into standard lead-shielded enclosures or fume hoods with ≥50 mm Pb equivalence
• Modular assay configuration: pre-validated method templates for ^99mTc-MDP, ¹⁸F-FDG, ⁶⁸Ga-DOTATATE, ¹⁷⁷Lu-PSMA, and other USP/Ph. Eur.-listed radiotracers
• Electromechanical safety interlocks compliant with IEC 61508 SIL2 requirements, including real-time radiation monitoring feedback loops and emergency shutdown protocols

Sample Compatibility & Compliance

The workstation accommodates standard radiopharmaceutical containers—including 10 mL serum vials, 30 mL HDPE syringes, and glass ampoules—with automatic barcode-based sample identification and traceability. All wetted components are constructed from gamma-stable materials (e.g., PTFE, sapphire, and 316L stainless steel) resistant to oxidation and radiolytic degradation. System validation documentation supports IQ/OQ/PQ execution per ASTM E2500-13 and aligns with FDA 21 CFR Part 11 for electronic records and signatures. Radiochemical purity analysis meets Ph. Eur. 2.2.47 and USP requirements for TLC solvent systems and R_f quantification accuracy (±0.02 R_f units). Radionuclidic identity verification satisfies ISO/IEC 17025:2017 criteria for energy calibration uncertainty (<0.5% at 140.5 keV).

Software & Data Management

Tailin’s QC-Studio™ software provides a 21 CFR Part 11–compliant environment featuring role-based access control, full audit trail logging (including user actions, parameter changes, and instrument status events), and electronic signature capture with biometric or PKI authentication. Raw spectral data, chromatograms, and calculation worksheets are stored in vendor-neutral formats (e.g., .cdf, .mzML, .csv) and exportable to LIMS via ASTM E1482-compliant interfaces. Method development tools include retention time prediction algorithms, peak deconvolution for overlapping isotopes (e.g., ⁶⁸Ga/⁶⁷Ga), and automated report generation compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

• Batch release testing of GMP-manufactured radiopharmaceuticals prior to clinical administration
• Stability-indicating assays tracking radiochemical decomposition over time (e.g., hydrolysis, transchelation, colloid formation)
• Method transfer and cross-site harmonization between centralized radiopharmacy facilities and satellite PET centers
• Regulatory submission support—including full traceability packages for FDA IND/ANDA filings and EMA marketing authorization applications
• Training and qualification of QC personnel using simulated radioactive sources and virtual workflow modules

FAQ

Does the workstation support both generator-produced and cyclotron-produced radionuclides?
Yes—it is validated for ^99mTc (from ⁹⁹Mo/^99mTc generators), ¹⁸F, ⁶⁸Ga, ⁶⁴Cu, ⁸⁹Zr, and ^{177</sup)Lu, with adjustable shielding configurations and detector gain settings per nuclide emission profile.
Can existing HPLC systems be retrofitted into this platform?
No—the workstation integrates a dedicated, gamma-hardened HPLC module with radiation-tolerant pumps, valves, and flow cells; third-party LC systems are not supported due to electromagnetic interference and material compatibility constraints.
Is remote monitoring and troubleshooting available?
Yes—via encrypted TLS 1.3 web interface with optional VPN tunneling; remote diagnostics require prior customer authorization and adhere to ISO/IEC 27001 information security controls.
What validation documentation is provided upon delivery?
Factory acceptance test (FAT) reports, installation qualification (IQ), operational qualification (OQ), and a customizable performance qualification (PQ) protocol template aligned with your internal SOPs and regional regulatory expectations.}
