Description
Convert an as-received marker fraction to a dry-mass fraction.
Botanical analytical records connect voucher identities, plant parts, extraction wording, moisture basis and marker units. A dry-basis fraction uses dry mass as its denominator, while a printed drug-extract ratio still needs its stated basis. Source labels and arithmetic do not authenticate a medicinal plant, establish potency or determine safe herbal use.
Convert an as-received marker fraction to a dry-mass fraction.
When to use this tool
Use Herbal Marker Dry Mass Correction when you already have asReceivedMarkerFraction, moistureFraction and need to convert an as-received marker fraction to a dry-mass fraction.
How to use the tool and how it works
- Enter asReceivedMarkerFraction, moistureFraction. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read dryBasisMarkerFraction. Use the output convention below.
Require markerFraction in [0,1], wet-basis moisture in [0,1) and markerFraction<=1-moisture; return marker/(1-moisture).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| asReceivedMarkerFraction | As Received Marker Fraction | Required. Finite number; minimum 0; maximum 1. |
| moistureFraction | Wet-basis water mass fraction below one; marker must not exceed dry mass fraction. | Required. Finite number; minimum 0; strictly below 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| dryBasisMarkerFraction | Dry Basis Marker Fraction | Required. Finite number. |

}Limitations and assumptions
- Marker and water fractions must describe the same received mass; the tool does not identify a botanical, validate an assay or determine potency or safety.
- 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
Review the original voucher, analytical method, moisture basis and reference-material documentation. Botanical identity, extraction basis and marker quantity require their own evidence; a recorded ratio or mass-basis conversion does not establish equivalence or medicinal suitability.
