Chemistry

Fit standard-addition spike data or use a fitted line to estimate unknown concentration from the negative x-intercept.

Estimate resin capacity, packed-bed volume, cycles, resin replacements, and resin-only campaign cost for chromatography planning.

Estimate preparative HPLC injections, mobile phase, solvent A/B volume, runtime, and solvent cost from your method and loading data.

Calculate matrix-spike volume, final fortification, recovery, dilution correction, and an optional method-limit check.

Calculate sodium hypochlorite feed rate, daily active chlorine use, pump setting, and usable tank life from flow and dose.

Calculate estimated LOD and LOQ from response SD and calibration slope. Record the SD source, units, and method multipliers.

Calculate corrected titrant concentration, a unitless correction factor, and blank-corrected titrant volume from standardization data.

Calculate RO antiscalant pump rate, daily neat product use, and 30-day chemical cost from flow, dose, density, dilution, and price.

Calculate direct reagent cost per test, batch, annual use, whole packages needed, and annual purchase spending.

Calculate purity-corrected mass for a molar solution, then plan a practical stock and aliquot using optional balance and transfer limits.
