Laboratory, Refining & Materials Testing

Engineering Decisions Begin with Accurate Material Analysis

Precision manufacturing begins with precision chemistry. At Sigmund Cohn Corp., our in-house analytical laboratory plays a critical role in ensuring the quality, purity, and performance of the precious metals and specialty alloys we manufacture.

Our laboratory supports manufacturing, quality assurance, refining, recycling, and customer investigations through comprehensive metallurgical testing and material verification. By combining advanced analytical instrumentation with decades of metallurgical expertise, we help customers ensure their materials meet demanding engineering, manufacturing, and regulatory requirements.

Refining & Precious Metal Recovery

One of the laboratory's primary functions is refining precious metals. Materials received from outside our manufacturing facility are considered impure and undergo refining processes designed to remove organic contaminants and base metal impurities. This enables valuable precious metals to be recovered, recycled, and returned to production while maintaining the highest standards of material quality and sustainability.

Advanced Analytical Testing

To verify material chemistry and product quality, our laboratory utilizes advanced analytical techniques, including:

  • Inductively Coupled Plasma (ICP) Spectroscopy

  • Atomic Absorption Spectrometry (AAS)

These technologies allow our team to identify trace metal impurities, verify alloy composition, and confirm compliance with customer specifications and recognized industry standards. Once materials have been refined and tested, a Certificate of Analysis (COA) is issued to document that the material meets the required specifications.

Failure Analysis & Technical Support

Our laboratory also supports customers through product evaluations and failure investigations. Materials returned through the RMA process may undergo comprehensive metallurgical testing to help determine the cause of a product failure, providing engineers with valuable insights that can improve product performance, manufacturing processes, and future designs.
