Helium Leak Detection

Helium leak detection (HeLD) is routinely used and widely accepted for applications that require the utmost leak sensitivity.

  • Helium is a small, non-reactive gas that is naturally rare in the atmosphere.
  • A custom-tuned spectrophotometer quantitatively measures the amount of helium escaping a package under vacuum.
  • Leakage is quantified to levels well below Maximum Allowable Leakage Limits (MALL) of most all product-package systems; ideal for package development and validation.
  • HeLD is currently used to fulfill test requirements or procedures in FDA guidance, EU Annex 1, ASTM F2391, USP <1207> and more.

One Technology, Many applications

Custom-designed and easy to change test fixtures enable a range of applications.
