Elemental Impurities
Elemental Impurities (Class I)
Quantitative ICP-MS analysis reports arsenic, cadmium, lead, and mercury for eligible natural products, botanical materials, dietary supplements, foods, beverages, and ingredients.
Share the complete product, matrix, intended market, and applicable specification. The laboratory confirms method-and-matrix fit, sample requirements, reporting needs, timing, and price during technical review.
For quote and submission: reference Test Code 301.
Quantitative Coverage
Four individually reported elements
Each element is reported separately. The defined panel is not a broad elemental screen and does not imply coverage of additional elements or elemental species.
- 01Arsenic (As)
- 02Cadmium (Cd)
- 03Lead (Pb)
- 04Mercury (Hg)
Product Pathways
Elemental-impurity testing across eligible matrices
These examples support initial routing only. The laboratory confirms whether the panel and reporting approach fit the submitted product before testing begins.
Natural products and botanicals
Eligible raw materials, powders, extracts, and other botanical preparations may be reviewed for the four-element panel.
Dietary supplements
Capsules, tablets, gummies, powders, and liquid supplements require product- and matrix-specific review.
Foods, beverages, and ingredients
Eligible food, beverage, agricultural, and plant-derived ingredient matrices may be scoped after the complete formulation and reporting question are provided.
Technical Review
Define the article, limit, and reporting decision
A concentration result alone does not select the applicable acceptance criterion. Include the product and exposure context so the laboratory can review the requested scope and reporting basis.
- Exact product, matrix, ingredients, and processing context
- Product category, intended use, and target market
- Applicable USP chapter, monograph, regulation, or customer specification
- Maximum daily dose or serving when acceptance criteria depend on exposure
- Required limits, reporting units, and decision rules
- Sample count, available quantity, and requested deadline
FAQ
Planning an elemental-impurities submission
Which elements are included in the four-element panel?
The panel quantitatively reports arsenic, cadmium, lead, and mercury. It does not imply coverage of additional elements.
Does the four-element panel certify USP compliance?
No. The test provides four individual elemental results. The applicable USP chapter, product category, daily dose or serving, monograph, acceptance limits, and decision rules must be defined before compliance can be evaluated.
Does the four-element panel include elemental speciation?
Do not assume a four-element result answers a species-specific question. If the project requires a particular form of arsenic, mercury, or another element, identify that need during technical review so the laboratory can confirm whether a separate approach is available.
What information should I include in a quote request?
Provide the exact matrix and formulation, product category, intended use and market, applicable standard or specification, maximum daily dose or serving when relevant, required limits and units, sample count, available quantity, and deadline.
