Description
Return sample and reference element/normalizer ratios and their ratio as enrichmentFactor.
Geochemical normalization compares a measurement with a supplied reference or reporting basis. Ratios remove compatible units, while rescaled concentrations retain a unit; a chosen reference is an assumption rather than an independently verified material standard.
Return sample and reference element/normalizer ratios and their ratio as enrichmentFactor.
When to use this tool
Use Element Enrichment Reference Ratio Term when you need one reference-normalization or reporting-convention calculation.
How to use the tool and how it works
- Enter sampleElement, sampleNormalizer, referenceElement, referenceNormalizer. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read sampleRatio, referenceRatio, enrichmentFactor. Use the output convention below.
Require nonnegative sampleElement and positive sampleNormalizer, referenceElement, and referenceNormalizer. Return sample and reference element/normalizer ratios and their ratio as enrichmentFactor.1

}Limitations and assumptions
- Concentrations need compatible units and reporting bases. The normalizer, reference material, and interpretation of enrichment are caller assumptions, not proof of contamination or geological origin.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use the complete analytical method and appropriate reference materials for interpretation. Align concentration units, dry/wet basis, detection-limit handling, and reference provenance before comparing samples.
