Elemental Analysis Testing Services

Elemental analysis can be qualitative, quantitative, or a combination of both. Qualitative analysis identifies which elements are present in a material, while quantitative analysis determines their concentrations. The appropriate testing approach depends on factors such as the sample matrix, target elements, expected concentrations, required detection limits, specifications, and applicable regulatory or quality requirements.

BA Sciences provides elemental analysis and elemental impurity testing for pharmaceutical raw materials, drug products, and other regulated materials. Our analytical capabilities include inductively coupled plasma mass spectrometry (ICP-MS), trace metals testing, heavy metals analysis, and atomic absorption spectroscopy (AAS).

Elemental testing may be used to:

• Identify and quantify elements in raw materials, drug products and other samples
• Detect and measure elemental impurities and unexpected contaminants
• Evaluate trace metals and heavy metals
• Support material characterization, purity, potency and quality evaluations
• Generate quantitative data for established specifications or acceptance criteria
• Support pharmaceutical development, investigations, release testing

Because elemental testing requirements vary by material, analyte, and application, BA Sciences works with clients to select an appropriate analytical approach based on the sample matrix, target elements, required sensitivity, and intended use of the data.

ICP-MS (inductively coupled plasma mass spectrometry) is a highly sensitive analytical technique used to identify and quantify metals and other elements at trace and ultra-trace concentrations. During ICP-MS analysis, the sample is introduced into an inductively coupled plasma, where elements are ionized. The resulting ions are then separated and measured based on their mass-to-charge ratios, enabling sensitive, multi-element analysis.

A key advantage of ICP-MS is its ability to measure multiple elements in a single analytical run while providing the sensitivity required for many trace-level applications. ICP-MS can also measure individual isotopes, supporting isotope-specific measurements and complex elemental analysis across a wide range of sample types.

At BA Sciences, ICP-MS is used for elemental analysis of pharmaceutical raw materials and other regulated materials, including applications such as trace metals analysis and elemental impurities testing. The appropriate method and sample preparation approach are selected based on the sample matrix, target elements, expected concentrations, and required limits of detection (LOD) and quantitation (LOQ).

For pharmaceutical programs requiring elemental impurities testing, BA Sciences provides dedicated analytical support to address applicable ICH Q3D and USP <232> and <233> requirements, including the evaluation and quantification of relevant elemental impurities.

Elemental analysis of pharmaceutical raw materials provides valuable information about elemental composition and can help detect and quantify trace elements, elemental impurities, and potential contaminants. This data can contribute to material characterization and quality assessment, helping pharmaceutical manufacturers confirm that incoming materials meet established specifications and quality requirements.

Depending on the material and its intended use, elemental analysis may be performed on active pharmaceutical ingredients (APIs), excipients, and other materials used in pharmaceutical manufacturing. Testing can identify unexpected elemental contaminants and determine whether specified elements are present within established acceptance criteria.

BA Sciences provides comprehensive pharmaceutical raw material testing, including elemental analysis by ICP-MS, trace element and elemental impurity testing, and metals analysis by atomic absorption spectroscopy (AAS). These capabilities can be incorporated into broader raw material testing programs when multiple chemical and physical attributes must be evaluated to support material qualification, quality control, and pharmaceutical manufacturing.

Elemental analysis and elemental impurities testing are related, but the terms are not interchangeable. Elemental analysis broadly identifies and may quantify elements present in a sample, while elemental impurities testing focuses on specific elements that may present safety concerns and must be controlled within established limits in pharmaceutical products.

ICH Q3D provides a risk-based framework for assessing and controlling elemental impurities in drug products. USP <232> establishes limits for specified elemental impurities in drug products, while USP <233> describes analytical procedures and validation expectations for determining elemental impurity levels.

BA Sciences has extensive experience supporting pharmaceutical elemental impurities testing using ICP-MS. Our scientists work with clients to determine an appropriate analytical approach based on applicable compendial and regulatory requirements, product specifications, sample matrix, target elements, and the intended use of the data.

Not every elemental analysis project can rely on an established compendial procedure. Differences in sample matrix, target elements, expected concentrations, or analytical requirements may require a method to be developed, optimized, or adapted for a specific application.

Elemental analysis method development considers factors such as sample preparation, target elements, calibration standards and reference materials, analytical range, and required sensitivity. Depending on the method and its intended use, performance characteristics such as limit of detection (LOD), limit of quantitation (LOQ), linearity, accuracy, precision, and specificity may also be evaluated.

LOD and LOQ are particularly important when selecting an analytical method. A method may be capable of detecting an element without reliably quantifying it at the concentration required by a specification or acceptance criterion. Defining the analytical objective and required sensitivity early in the project helps ensure the method generates data suitable for its intended purpose.

BA Sciences also provides analytical method development and validation support and other analytical applications, with methods tailored to specific materials, products, specifications, and regulatory requirements.

What does an elemental analysis tell you?

Elemental analysis identifies which elements are present in a sample, while quantitative elemental analysis determines their concentrations. The results can help characterize elemental composition, detect trace elements and potential contaminants, support purity and quality assessments, and determine whether specified elements meet established acceptance criteria.

What is the procedure for elemental analysis?

The procedure for elemental analysis depends on the sample matrix, target elements, required sensitivity, and analytical technique. A typical process involves defining the analytical requirements, preparing the sample, calibrating the instrument with appropriate standards, measuring the target elements, and evaluating the resulting data against applicable specifications or acceptance criteria.

Techniques such as ICP-MS and atomic absorption spectroscopy (AAS) may require different sample preparation and analytical procedures depending on the material and intended use of the results.

How long does elemental analysis testing take?

Turnaround time for elemental analysis depends on the sample matrix, number of target elements, analytical technique, sample preparation requirements, and whether method development or validation is needed. BA Sciences works with clients to define testing requirements, deliverables, and expected timelines before analysis begins.
