Trace Elemental Analysis (ICP-MS & ICP-OES) Testing Techniques
Trace elemental analysis identifies and quantifies metallic and inorganic impurities from major elements down to trace levels. At Lucideon, we apply ICP-MS for ultra-low detection limits, and ICP-OES for rapid multi-element quantification at low-to-mid ppm levels - providing precise data you can trust for product release, problem-solving, and compliance. Our chemical analysis laboratories are UKAS ISO/IEC 17025:2017 accredited, with methods tailored to your matrix and regulatory needs.
Why choose Lucideon for trace element analysis?
- Ultra-trace sensitivity - ICP-MS routinely reaches trace level detection with mass-selective specificity for elemental and isotopic confirmation
- Speed for multi-element panels - ICP-OES rapidly quantifies a broad suite of elements for screening, trending, and process control
- Method selection that fits the risk - we choose ICP-MS, ICP-OES, or a combined approach to balance sensitivity, speed, interferences, and cost. (Common industry practice pairs ICP-MS for trace/ultra-trace with ICP-OES for majors/minors.)
- End-to-end expertise - from sampling guidance and digestion strategy through to data interpretation and corrective actions, drawing on our wider testing and consultancy expertise
- Integrated with wider testing - we can combine trace elemental analysis with broader chemical analysis, mechanical testing, and microstructural evaluation, giving you a single laboratory partner for both composition and performance assessments of advanced materials and components
What we test and why it matters
- Pharmaceuticals & medical - elemental impurities to ICH Q3D; extractables & leachables for devices/packaging (e.g., metals from elastomers, polymers, glass)
- Advanced materials & components - alloy verification, contamination control, raw-material qualification across metals, ceramics, polymers, and composites
- Nuclear, energy & defence - determination of detrimental elements and halides to support material selection and compliance (e.g., MIL-STD)
- Biomaterials & coatings - trace metals in hydroxyapatite and coated implants
Techniques we use
ICP-MS (Inductively Coupled Plasma - Mass Spectrometry). Trace quantification with mass and isotope selectivity; ideal for ICH Q3D, impurity profiling, and leachable metals at very low levels.
ICP-OES (Inductively Coupled Plasma - Optical Emission Spectroscopy). High-throughput, multi-element quantification for majors, minors, and many trace elements - ideal for routine screening and process control
We often combine ICP-MS and ICP-OES to cover a very wide concentration range efficiently
Typical deliverables
- Clear, decision-ready reports - method, calibration, detection limits, QC checks
- Actionable interpretation - what results mean for specification, process, or compliance
- Optional corroboration - link with SEM-EDX, XRD, EPMA or surface analysis when morphology or near-surface chemistry is important
Example use cases
- ICH Q3D elemental impurities panel for drug product or API
- Extractables/leachables investigations on devices and packaging
- Detrimental elements/halides verification for defence/nuclear programmes
- Raw material qualification and contamination trending for advanced manufacturing
- Trace metals in bio-ceramics (e.g., hydroxyapatite)
How we ensure quality
Our laboratories operate to UKAS ISO/IEC 17025:2017, with validated methods, matrix-matched calibration where required, and robust QA/QC (blanks, spikes, CRMs). Where appropriate, we align testing to recognized standards (e.g., ICH Q3D, ISO methods, MIL-STD).

Inductively Coupled Plasma (ICP) analysis is a powerful technique used to detect and quantify trace elements in various samples with high precision and accuracy. Utilizing a plasma source that reaches temperatures of up to 10,000°K, ICP excites atoms and ions, causing them to emit light at characteristic wavelengths. By measuring this emitted light using a spectrometer, the concentrations of elements, even at trace levels, can be accurately determined. ICP analysis is widely employed in industries such as environmental monitoring, pharmaceuticals, metallurgy, and food safety due to its ability to analyse multiple elements simultaneously with low detection limits and excellent reproducibility.
