What is Surrogate Powder Testing?

Surrogate Powder Testing assesses how well your containment systems protect workers from potent pharmaceutical compounds. By using safe, specially designed materials that mimic real drugs, we measure containment performance to ensure worker safety and product integrity without exposure risks.

Why is Testing Essential?

Potent compounds, including APIs and biologics, can cause serious harm if containment systems fail. Our comprehensive testing identifies potential weaknesses, validates system effectiveness, and ensures compliance with strict regulatory requirements, protecting both your people and operations.

Your Partner in Safety Excellence

Indivirtus Healthcare Services combines cutting-edge analytical techniques with deep regulatory expertise to deliver customized testing solutions. As your trusted CRO partner, we provide actionable insights that help maintain safe, compliant, and efficient pharmaceutical manufacturing operations.

Our Proven Testing Methodology

At Indivirtus Healthcare Services, we follow a rigorous, science-based approach to validate pharmaceutical containment systems. Our process starts with a risk-based test protocol specifically designed for your equipment and compounds. We employ fluorescent tracers like sodium fluorescein for immediate breach detection, combined with carefully engineered lactose/naproxen blends that accurately replicate your target API particle characteristics. For biologic applications, we use specialized surrogate APIs to ensure test relevance.

Our comprehensive testing approach includes real-time airborne particle monitoring combined with synchronized video recording for precise contamination tracking. We create detailed 3D contamination maps using UV-visible tracers and perform quantitative analysis through HPLC, achieving remarkable detection limits as low as ng/cm². For cytotoxic applications, our ultra-sensitive LC-MS/MS analysis ensures exceptional accuracy. Every test includes worst-case scenarios—like equipment failures or incorrect PPE use—to thoroughly challenge your systems and confirm reliability. Results are compared against Occupational Exposure Limits (OELs) and aligned with ISPE SMEPAC guidelines.

Frequently Asked Questions

Frequently Asked Questions

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.
