Specification control
Target purity and composition are clarified before commercial confirmation.
Quality and documentation
Precision begins before the offer.
Product, grade, packaging and document requirements are reviewed as one commercial context.
Documentation follows the product
We identify the information needed for the requested grade, packaging, destination and intended use.
Quality records
Available certificates and supporting records are identified with the offer.
Safety information
Safety documentation is considered against product and transport context. Review the controlled Safety Data Sheet register.
Packaging review
State, pressure, volume, valve and handling requirements are clarified. For existing cylinders, see why a change of gas service needs a separate review.
Transport documents
Route-specific transport and customs records are reviewed where applicable.
Change control
Material changes to the request are reconfirmed before the next commercial step.
Product analysis against the agreed specification
Quality control starts with documented limits. The applicable analytical checks depend on the gas, grade, package and intended use.
Sample identificationProduct, batch and sampling context are recorded.
Moisture and oxygen checksRelevant trace readings are reviewed against the agreed limits.
Multi-component analysisSpecified impurities are screened using the applicable analytical method.
Results and release documentationReviewed data supports the applicable Certificate of Analysis.
Checks at the delivery point
Instrument verification starts with a defined reference. Review calibration gas and mixture requirements.
Portable analytical equipment can support checks at the delivery interface. The method, sampling point and acceptance criteria must be agreed for the gas and application.

The photographs illustrate analytical workflows, not results for a specific batch or shipment. The agreed specification and applicable Certificate of Analysis remain the determining documents. Published specification examples are available for neon, xenon, krypton and GeH4. Our high-purity gas analysis guide explains complementary methods, sampling and reporting limits.
