Available tools
- Aqueous Speciation One Equilibrium Ratio Tool One activity-based complexation mass-action term; ligand is free activity and mass-balance speciation is not solved.
- Blank Corrected Trace Element Mass Tool Subtract an explicit trace-element blank mass from sample mass in matching units without clipping signed analytical residuals.
- Element Enrichment Reference Ratio Term Tool Calculate element enrichment reference ratio term from explicit caller-supplied inputs.
- Element Oxide Basis Factor Tool Derive one stoichiometric element/oxide mass multiplier from explicitly identified formula metadata and supplied atom counts/masses; no mineral identity or formula parsing.
- Geochemical Detection Limit Substitution Flag Tool Explicit caller-requested substitution for censored observations with an audit flag; not an inferential recommendation.
- Geochemical Dry Wet Concentration Crosswalk Tool Calculate geochemical dry wet concentration crosswalk from explicit caller-supplied inputs.
- Geochemical Dryash Basis Flag Tool Concentration basis crosswalk under a caller-asserted constituent-retained-in-ash assumption.
- Geochemical Loss On Ignition Basis Tool Signed gravimetric loss on ignition; oxidation-related mass gain appears as negative LOI.
- Geochemical Reference Deviation Factor Tool Calculate geochemical reference deviation factor from explicit caller-supplied inputs.
- Geochemical Replicate Censored Pair Code Tool Preserve explicitly supplied replicate-pair censoring metadata without substituting values or computing precision from censored results.
- Geochemical Single Element Closure Residual Subtract a supplied expected mass from measured mass for one element without compositional fitting.
- Geochemical Spike Native Mass Ratio Tool Divide supplied geochemical spike mass by positive native-analyte mass on a consistent elemental or isotope basis.
- Geochemical Standard Recovery Compare a supplied measurement with an explicit positive reference value without selecting analytical acceptance limits.
- Geochemical Volatile Free Normalization Term Tool Calculate geochemical volatile free normalization term from explicit caller-supplied inputs.
- Isotope Activity Decay Reference Date Term Tool Shift explicit reference isotope activity by signed elapsed time under a supplied first-order decay constant in matching time units.
- Isotope Delta To Ratio Standard Term Tool Delta notation delta=1000*(Rsample/Rstandard-1), with an explicit positive standard ratio.
- Isotope Mixing Two Endmember Fraction Tool Exact ratio mixing when concentrations measure denominator-isotope amount per mass, rather than total element concentration.
- Isotope Parent Daughter Decay One Step Tool Closed-system one-parent-to-one-stable-daughter decay without intermediate chains.
- Isotope Ratio Denominator Label Label explicit isotope-ratio numerator, denominator, and reference wording without isotope lookup or normalization.
- Isotope Ratio Mass Bias Reference Term Tool Solve beta from measured/reference isotope ratio=(numerator/denominator isotope mass ratio)^beta using the explicitly ordered mass ratio.
- Isotope Ratio Mixing Weight Tool Mix isotope ratios using explicit denominator-isotope amounts, not bulk mass weights.
- Isotope Reference Delta Offset Tool Rebase isotope delta notation in per mille using two explicit compatible reference ratios.
- Isotope Standard Delta Residual Tool Compare a supplied isotope delta notation to a supplied positive standard ratio without choosing isotope standards.
- Loss On Ignition Mass Gap Tool Compare measured ignition mass change with an explicit reference; mass gains remain visible.
- Mineral Cation Valence Uncertainty Range Tool Continuous valence-mixture charge range; does not assert that intermediate integer valence states exist.
- Mineral Formula Occupancy Residual Compare explicit mineral-site occupancy contributions to a supplied capacity without assigning valences or sites.
- Mineral Hydroxyl Anion Oxygen Equivalent Tool Formal anion charge accounting for O2-, OH-, F- and Cl-, without mineral identification.
- Mineral Oxide Molar Proportion Term Tool Calculate mineral oxide molar proportion term from explicit caller-supplied inputs.
- Mineral Oxygen Basis Factor Scale one supplied cation amount to an explicit oxygen basis without determining mineral stoichiometry.
- Mineral Site Occupancy Vacancy Budget Tool Calculate mineral site occupancy vacancy budget from explicit caller-supplied inputs.
- Mineral Site Valence Budget Tool Calculate mineral site valence budget from explicit caller-supplied inputs.
- Oxide Analysis Anhydrous Component Weight Tool Renormalize one explicitly supplied oxide component to a water-excluded total without inferring mineralogy or missing components.
- Oxide Element Molar Factor Sign Tool Formal elemental inventory with supplied stoichiometry/molar mass and a signed correction; no oxide composition table.
- Oxide Stoichiometry Normalization Term Tool Apply explicit oxide-to-cation and normalization factors without a mineral formula table.
- Rare Earth Chondrite Normalized One Element Tool One normalized element and geometric-neighbor anomaly from explicitly sourced reference concentrations.
- Rare Earth Eu Anomaly Reference Term Tool Calculate Eu/Eu-star using explicitly reference-normalized Eu divided by the geometric mean of normalized Sm and Gd.
- Rare Earth Reference Normalization Normalize one rare-earth concentration to a supplied same-unit reference without providing a reference abundance table.
- Rock Powder Dilution Blank Correction Tool Blank-corrected digest concentration converted to sample mass basis in caller-consistent units; negative blanks-corrected results are retained.
- Sample Dry Mass Support Share Tool Calculate sample dry mass support share from explicit caller-supplied inputs.
- Sediment Elemental Titanium Normalization Term Tool Calculate sediment elemental titanium normalization term from explicit caller-supplied inputs.
- Sediment Extraction Step Fraction Label Tool Preserve an explicit sediment extraction step and operational fraction label without assigning chemical speciation.
- Sulfur Isotope Mass Dependent Offset Term Tool Nonlinear capital-delta anomaly relative to an explicitly supplied mass-dependent exponent; deltas are per mil.
- Trace Element Nondetect Interval Return an explicitly supplied nondetect interval without substituting a concentration estimate.
- Trace Element Reference Gap Tool Calculate trace element reference gap from explicit caller-supplied inputs.
- Water Rock Mass Ratio Label Tool Preserve an explicit water-rock mass ratio transcription and basis without equating mass and volume ratios.
