Contaminant & Impurity Analysis

Protect Your Products Before Contamination Reaches Consumers

Identify Unknown Contaminants and Impurities—and Evaluate Their Probable Source

Contaminant and impurity analysis is about more than detection—it is about understanding what the unknown material is, where it may have come from, and how it could affect product quality. Quantum Analytics Group investigates unexpected particles, residues, chemical impurities, odors, discoloration, precipitates, residual solvents and unknown peaks in raw materials, packaging, manufactured components and finished products.

Using complementary analytical techniques, our scientists identify and characterize organic and inorganic impurities, compare findings with suspected sources, and develop clear, actionable conclusions that help prevent production delays, protect product performance and reputation, and reduce the risk of costly recalls.

SOME OF THE MANY PROBLEMS WE INVESTIGATE

When Something Unexpected Appears in Your Product

Product contamination does not always present as an obvious foreign object. It may appear as a subtle chemical difference, an unusual odor, a deposit, a change in color, texture or performance.

MicroscopeForeign Particles

Black specks, fibers, fragments, flakes, metallic debris and other visible foreign materials.

Actives

Surface Residues and Deposits

Films, stains, oily residues, powders, bloom, buildup and material affecting adhesion or product appearance .

impuritiyOff-Odors and Volatile Compounds

Unexpected odors associated with formulations, raw materials, packaging, processing or storage.

Yellowing, staining, darkening, haze and other unexpected changes in product appearance.

Actives

Precipitates And Sediment

Unexpected solids, crystals, sediment or phase changes in liquid and formulated products.

HOW ANALYTICAL FINDINGS SUPPORT PRODUCT and PROCESS DECISIONS

When unexpected contaminants or impurities appear, understanding what they are is often the first step toward resolving the problem. These real-world investigations demonstrate how Quantum Analytics Group combines scientific expertise with complementary analytical techniques to identify unknown materials, compare suspected sources, and provide clear, actionable results.

Polymer Product

Unknown black particle in molded components

Problem: Intermittent black particles appeared in finished components produced from a polymer resin.

Approach: Particles were isolated and compared with the base polymer and suspected process-contact materials using complementary microscopic and chemical methods.

Outcome: The analytical profile helped the manufacturer narrow its process investigation and focus corrective-action efforts.

Packaging Product

Unexpected odor after product storage

Problem: A finished product developed an odor that was not present immediately after manufacturing.

Approach: Volatile compounds from affected and control samples were compared with potential formulation and packaging sources.

Outcome: The findings supported evaluation of packaging materials, storage conditions and future product monitoring.

Manufacturing Component

Surface residue affecting adhesion

Problem: A thin residue was discovered on a component after an adhesion failure.

Approach: The residue was characterized and compared with process aids, cleaning substances and other suspected materials.

Outcome: The client used the analytical comparison to refine its cleaning and process-control investigation.
