Quality Control

A Focus on Accuracy and Precision

Our team of expert quality professionals is Zochem’s ultimate resource to ensure their teammates deliver superlative products to our customers. We always remain focused on our “built-in-quality” mindset.

Our Laboratory

The inside story of how we maintain the industry’s highest quality control standards for Zinc Oxide.

The accuracy and confidence derived from precisely documented results, obtained in our state-of-the-art laboratories, are paramount to the success and growth of Zochem internationally. Customers worldwide recognize Zochem’s quality-conscious approach underpinned by our reliable testing, consistent manufacturing processes, and dependable staff.

Zochem’s operational systems have been integrated with the safety and quality expectations of our customers to ensure process capability and versatility that meet the expectations of even our most discerning clients. Our laboratory extends much further than its physical location. A Genchi Genbutsu (“Go and See”) mantra engenders a continuous improvement environment for enhanced detection of issues through error-proofing. Along with our focus on preventative actions, we reduce or eliminate the frequency of QC challenges our customers might otherwise find unacceptable.

Zochem is FDA, Health Canada, and European ICH Q7A approved which signifies our customer can also be a ‘patient’. Our laboratory equipment is supported by extensive procedures and practices to ensure the patient’s welfare is given the utmost priority. Our laboratory’s best practices are accentuated by our Quality team’s consistent input.

Mona Ghanam and Cheril Norville represent commitment, leadership, and honesty as our two Quality Control and Assurance Managers in Brampton, Ontario, and Dickson, Tennessee respectively.

Mona Ghanam explained the following concerning pharmaceutical testing “The process begins before manufacturing. An identity test for the zinc metal is performed for every lot received from the zinc supplier. Impurity tests are then performed periodically to ensure that the supplier Certificate of Analysis matches Zochem’s internal testing. Zochem uses special high-grade zinc to produce various grades of French Process zinc oxide. The purity level of the zinc metal must be at 99.995% as a minimum.”

Cheril Norville commented “The Lab is the gatekeeper and is where the quality control testing is done, independently and autonomously, to confirm the properties and purity of French process Zinc Oxide. Once this is complete, a Certificate of Analysis (COA) is generated for each customer. Before the material is shipped, a final inspection is performed to ensure all shipping and labeling requirements have been met.”

Our Quality team works closely with Operations to ensure that inputs are understood and controlled to ensure the successful provision of the predictable output our customers demand. Zochem’s investment in sustainable and robust Muffle Furnaces supports this culture.
