How do you select appropriate surrogate materials for specific APIs?
We match surrogates to APIs based on: 1) Particle size distribution (laser diffraction analysis), 2) Morphology (SEM imaging), 3) Electrostatic properties, and 4) Flow characteristics - using engineered lactose blends or custom particles when needed to accurately simulate challenging APIs.
Can surrogate testing validate containment for nanogram-potent compounds?
Yes, we use: 1) Fluorescent tracers detectable at <1ng/cm², 2) LC-MS/MS analysis for specific surrogate compounds, and 3) Statistical extrapolation models to verify containment at required levels for ultra-potent compounds.
How does Annex 1 (2022) impact surrogate testing approaches?
The updated Annex 1 requires: 1) Integration with Contamination Control Strategy, 2) More frequent performance verification, and 3) Linkage to media fill simulations for aseptic processes. Our testing protocols include these elements with documented correlations.
What's the advantage of time-synchronized video and particle data?
Synchronization allows: 1) Precise identification of contaminant-generating activities, 2) Correlation of particle counts with specific operations, and 3) Visual evidence for training and procedure optimization - creating a powerful diagnostic tool.
Can you test containment for large-scale manufacturing equipment?
Yes, we've developed scalable methods for: 1) Bin blenders and fluid bed dryers, 2) Continuous manufacturing lines, and 3) Large-scale isolators - using distributed sampling arrays and computational fluid dynamics modeling to extrapolate results.
What is the purpose of Surrogate Powder Testing?
Surrogate Powder Testing validates the integrity of containment systems used for handling potent pharmaceutical compounds. It uses safe, engineered materials to simulate real-world conditions, ensuring worker safety, product purity, and regulatory compliance.
How does Indivirtus ensure accurate results?
We employ advanced techniques including fluorescent tracers, real-time particle monitoring, and HPLC analysis with detection limits to ng/cm². For cytotoxic applications, we use ultra-sensitive LC-MS/MS, ensuring precise and reliable results.
What regulatory standards does your testing follow?
Our testing adheres to ISPE SMEPAC Guidelines (2021), EU GMP Annex 1 (2022), OSHA 29 CFR 1910.1000, NIOSH Hazardous Drug Handling Guidelines, EMA Health Based Exposure Limits, and ISO 14644-7 for cleanroom isolators.
What deliverables can I expect from the service?
You'll receive a risk-based test protocol, detailed contamination heat maps, synchronized video/particle data, quantitative performance metrics, OEB comparative analysis, an engineering control roadmap, and regulatory-ready documentation.
When should I use Surrogate Powder Testing?
This service is ideal for commissioning new containment systems, routine validation, troubleshooting breaches, or preparing for regulatory audits. It's essential for handling potent APIs, biologics, or cytotoxic drugs.
How does Indivirtus ensure confidentiality?
