Description
One supplied linear assay-reference mass calculation without identifying a substance.
Botanical laboratory records distinguish wet mass, dry matter, carriers, extract mass, and assay response. A fraction or reference comparison depends on the chosen material basis and supplied analytical method. Voucher and monograph metadata help identify records but do not themselves authenticate a specimen or establish product quality.
One supplied linear assay-reference mass calculation without identifying a substance.
When to use this tool
Use Botanical Marker Supplied Assay Content Term when you need this mass-basis, assay-response, extraction, or source-record calculation for supplied laboratory data.
How to use the tool and how it works
- Enter sampleSignal, blankSignal, referenceSignal, referenceMass, sampleMass, dilution. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read correctedSignal, markerMass, massFraction. Use the output convention below.
For positive referenceSignal, referenceMass, sampleMass, and dilution return correctedSignal=sampleSignal-blankSignal, markerMass=correctedSignal*referenceMass*dilution/referenceSignal, and massFraction=markerMass/sampleMass.1

}Limitations and assumptions
- Signals need a common response scale and masses one unit. Negative corrected signal and fractions outside zero through one are allowed; calibration, specificity, recovery, identity, and product safety are not established.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Use the appropriate authenticated reference material, analytical protocol, and source records for a full laboratory assessment. Verify moisture basis, response factors, and extract/carrier definitions before comparing results.
