Unknown Contaminant Identification
Identify unknown particles, residues, stains, foreign material, or mixed components using orthogonal chemical and physical evidence.
Contaminant and impurity analysis services for unknowns, particles, residues, trace signals, and root-cause investigations.
This section summarizes Triclinic’s contaminant and impurity analysis pages for unknown contaminant identification, impurity identification, root-cause investigations, trace-level analysis, elemental quantification, counterfeit analysis, and extractables and leachables. These pages connect the investigation question to the right combination of microscopy, spectroscopy, chromatography, mass spectrometry, elemental analysis, and reference comparisons.
Contaminant and impurity service areas
Use these pages when a visible or microscopic particle, residue, unknown peak, elemental signal, foreign material, suspect product, or leachable/extractable concern must be identified or interpreted in context.
Impurity Identification
Identify process impurities, degradants, unknown peaks, and low-level components using chromatography, MS, NMR, MicroED, and spectroscopy when appropriate.
Root Cause Investigations
Connect material identity, morphology, source comparisons, process history, and batch context to deviation, OOS, or manufacturing investigations.
Trace Level Analysis
Support investigations where the target is low-level, matrix-interfered, sparse, microscopic, or difficult to isolate.
Elemental Quantification
Quantify elemental signals and interpret inorganic, metallic, mineral, catalyst, residue, or source-related findings.
Counterfeit Analysis
Compare suspect products, ingredients, particles, packaging-related materials, or formulation signatures to support counterfeit or authenticity investigations.
Extractables & Leachables
Evaluate material-related extractable or leachable concerns involving packaging, devices, components, residues, or product-contact materials.
How to use this section
Start with the failure mode and available comparison materials. A visible particle, an unknown chromatographic peak, a residue, an elemental signal, and a suspected counterfeit require different sample preparation and analytical paths.
Common Questions
What should be sent for a contaminant or impurity investigation?
Send the unknown material if available, retained acceptable lots, suspect lots, process materials, packaging, cleaning agents, suspected sources, photos, prior data, and chain-of-custody or sampling context.
Can Triclinic identify mixed or microscopic materials?
Often yes, but the conclusion may require microscopy, Raman, FTIR, SEM/EDX, chromatography, MS, elemental analysis, and reference comparisons rather than one technique.
Can this support quality or manufacturing investigations?
Yes, when the scope includes relevant comparison materials, material history, sampling context, and documentation appropriate to the investigation.
What if the unknown is only a trace-level signal?
Trace-level work may require targeted preparation, enrichment, high-sensitivity methods, or orthogonal follow-up to separate real signals from matrix interference and artifacts.
How much material is needed for an investigation?
The amount depends on particle size, concentration, sample matrix, homogeneity, and the techniques required. Small visible particles may be analyzed individually, while trace-level or heterogeneous samples may require more material, enrichment, separation, or replicate preparation.
Investigate a contaminant or impurity
Send the material, current data, suspected sources, comparison samples, project objective, quality requirements, and timeline.
