Head Space Analyzer Module for Quality Control Leak Testing

Head Space Analyzer Module for Quality Control Leak Testing

Helium leak testing is a non-destructive method to verify the presence of a leak in a component or device by using helium as a tracer gas. Being a highly sensitive method, it measures the amount of helium escaping through the package and is stated as a leak rate. Helium leak detection using Seal Integrity Monitoring System (SIMS) 1915+ is widely used in pharmaceutical and medical device product package systems for quality checking. SIMS 1915+ enable quantitative CCI analyses of packages at a sensitivity level as low as 1 x 10-10 mbar/L/sec. This quantitative method enables direct comparison across multiple packaging materials and formats, production line settings, and stability storage conditions. Each SIMS 1915+ Helium Leak Testing device is custom-built to meet the specifications and packaging configurations of the client. The following are the SIMS 1915+ configurations for CCI.

  • Headspace Analyzer Module (HSAM)
  • Helium Leak Detector Module
  • External Calibrated Helium Leak Standard
  • Dual Test Port Manifold
  • Vacuum Test Fixture Model (VTFM)

Quality Control Leak Testing using LDA's Head Space Analyzer Module

The Head Space Analyzer Module (HSAM) is a critical component of a Leak Detection Associates (LDA) custom helium leak testing system. The Model VM-2, created by Leak Detection Associates, is the most recent version of this unique device. The HSAM includes a probe, which is essential for determining the helium concentration in the headspace of the container system. This system is simple to use and operate since it has an Integral Calibration Chamber with a Calibrant Gas Flow Control Valve and a Universal Holder that allows multiple diameter systems to be evaluated. Leak Detection Associates will provide three (3) Puncture Probes (two spares) with each unit.

The optional vial filling component enables the test preparation of already-sealed vials by replacing the headspace gas with 100% helium. This module can be used to prepare samples at the moment of testing, after capping, or to prepare samples that have been stored for a period of time prior to testing. When combined with the VM-2, these unique attachments enable accurate and sample-specific readings that may be integrated into flexible study designs.

Uses of Helium Leak Detection

  • Ensuring container closure integrity.
  • Seal integrity monitoring during stability studies.
  • Verify and predict shelf-life seal integrity.
  • Useful in the early-stage drug product package system development.
  • Selecting closure formulation and configuration.

LDA's Head Space Analyzer Module (HSAM) - SIMS 1915+ configuration ensures highly sensitive leak detection of pharmaceutical pouches. Cold form blister cards, parenteral vials, cartridges, pre-filled syringes, bottles, combination product systems, and medical device products are other applications.
