Non-Destructive Inline CCIT for High-Speed Pharmaceutical Production

The pharmaceutical industry faces mounting pressure to ensure 100% container closure integrity and headspace accuracy while maintaining high-speed production rates. Traditional destructive testing methods force manufacturers to choose between comprehensive quality assurance and operational efficiency, creating gaps in compliance and increasing product waste.

Modern pharmaceutical production demands a solution that delivers complete container closure integrity testing (CCIT) inspection on the production line without compromising throughput, destroying product samples, or requiring routine daily calibration procedures.

Gasporox provides LineArch™ as a standalone, plug-and-play solution designed for straightforward integration into production lines.  This article addresses the most common questions manufacturers ask when seeking to integrate automated LineArch™ non-destructive inspection for vials, ampoules, and bottles on high-speed production lines.

What are the options for non-destructive inline headspace inspection systems?

Gasporox LineArch™ provides a completely non-destructive and non-intrusive headspace gas inspection solution based on Tunable Diode Laser Absorption Spectroscopy (TDLAS). The system measures headspace oxygen and water vapor content by sending laser light through pharmaceutical containers as they pass on the production line, analyzing gas composition without opening or damaging any products.

This technology was available from Gasporox previously as discrete VialArch™ and BottleArch™ sensor modules respectively shaped for small and large volume containers. However, these needed to be fitted separately to the line, requiring some engineering and system integration expertise.

In contrast, LineArch™ is a self-contained standalone plug-and-play unit that simply needs to be placed alongside the line and plugged into electrical and comms ports. The LineArch™ platform incorporates the mechanical, electrical, and electronic components required for inline inspection and can be equipped with either Vial Arch™ or BottleArch™ sensors. This integration makes it very simple to set up.

In either format, LineArch™ can be directly integrated into existing lines as a standalone solution or as a complement to other machines to enable true 100% testing of both small and large volume parenterals.

Do inline pharmaceutical inspection systems require specific calibration?

The Gasporox LineArch™ offers a parameter-free operation for container format changes, eliminating the need for routine recalibration. In VialArch™ form, it handles vials from 2R to 100R diameter, while the BottleArch™ configuration accommodates bottles up to 105mm diameter. The system’s self-calibrating functionality eliminates the need for daily maintenance or calibration procedures, making it a true plug-and-play solution. LineArch™ measures oxygen from 0-100% with typical accuracy of +0.4% O₂ and can detect water vapor for total pressure measurements ranging from 10-1050 mbar, all without requiring manual adjustments or parameter settings for different container formats.

How accurate is LineArch™?

For bottles and large containers, Gasporox LineArch™ achieves typical precision of 0.1-0.2% O₂ at 300 mm/s belt speed. In its VialArch™ configuration, the system can process production lines running with a minimum 1 vial diameter gap between containers, while the BottleArch™ version can handle LVP containers spaced as close as 12mm apart. The TDLAS technology provides consistent accuracy, delivering 0.2% O₂ precision at 300 mm/s for both configurations. This performance enables real-time detection of container closure defects and gas ingress during full-speed production without creating bottlenecks or requiring product sampling.

What integration is required to add inline headspace analysis to pharmaceutical production lines?

LineArch™ is designed as an integration-ready system that connects to existing inspection machines and production lines through standard industrial interfaces. The system provides Serial RS422 and USB communication ports, along with Digital I/O (0-24V) for input/output communication with line controllers. Its compact, IP-rated stainless-steel and anodized aluminum architecture is suitable for GMP production environments.

Gasporox delivers LineArch™ with their measurement concept, meaning their technical team works directly with customers to customize and optimize the system for specific container types, production speeds, and inspection requirements, ensuring seamless integration into existing manufacturing environments.

Can one inspection system perform both oxygen measurement and leak detection?

The Gasporox LineArch™ TDLAS/HSA technology can measure oxygen (O²) and carbon dioxide (CO₂) total pr partial density in container headspace as key indicators of product integrity (detecting gas ingress for CCIT. Separately, it can also measure moisture (H₂0) levels from 0-25 mbar partial pressure within total pressures of 10-1050 mbar for internal pressure-based leak detection.

This dual capability allows manufacturers to verify either proper initial fill conditions or ongoing container closure integrity using single inline measurement points, providing comprehensive quality assurance for oxygen-sensitive pharmaceutical products throughout the production process.

What pharmaceutical container formats work with automated inline inspection systems?

The Gasporox LineArch™ system supports an extensive range of pharmaceutical containers through its two main configurations. VialArch™ is optimized for small to medium vials (2R to 100R diameter) and ampoules, accommodating tubular glass vials, molded vials, plastic vials, and amber glass containers. BottleArch™ extends inspection capabilities to larger containers up to 105mm diameter, including large volume parenterals (LVP) and pharmaceutical bottles. The laser-based TDLAS measurement technique works effectively with both transparent and semi-opaque glass materials, eliminating container-specific setup requirements. Each LineArch™ system is custom configured for the customer’s specific container portfolio and production line requirements.

Is laser-based inspection safe for operator exposure in pharmaceutical manufacturing?

Gasporox LineArch™ employs completely eye-safe laser technology that poses no risk to operators or quality control personnel working near the inspection system. The low-power tunable diode lasers used in the TDLAS measurement process are specifically designed for safe operation in pharmaceutical production environments without requiring special protective barriers or safety interlocks beyond standard CE marking compliance. The system meets EMC 2014/30/EU and Low Voltage Directive 2014/35/EU requirements, ensuring it operates safely within regulated pharmaceutical manufacturing facilities. The non-intrusive measurement method requires no physical contact with containers and generates no harmful byproducts, making it suitable for cleanroom and controlled environment installations.

How do I ensure regulatory compliance with inline headspace testing equipment?

The Gasporox LineArch™ uses TDLAS technology, which aligns with the deterministic testing principles described in USP <1207> and supports compliance with EU GMP Annex 1 requirements for sterile manufacturing. The deterministic measurement approach provides quantitative data that supports validation protocols and regulatory submissions, unlike subjective pass/fail methods. Calibration-free LineArch™ operation and consistent measurement performance simplify validation documentation and ongoing compliance verification. The system operates on 24V/2A DC power (range 18-30V DC) with standard industrial communication protocols, which aligns with the deterministic testing principles described in USP <1207> for pharmaceutical container testing and supports compliance with FDA 21 CFR Part 11, as well as  EU GMP Annex 11 and Annex 1 expectations for sterile manufacturing.
