mf-from-ea v2.1.13

mf-from-ea

Find a molecular formula from the result of an elemental analysis based on a molecular formula range.

Installation

$ npm install --save mf-from-ea

Usage

const { mfFromEA } = requier('mf-from-ea');

let result = mfFromEA(
  { C: 0.8, H: 0.2 }, // elemental analysis result: 80% C, 20% H
  {
    ranges: 'C0-10 H0-20', // range of molecular formula to explore
    maxElementError: 0.003, // 0.3% Allowed error for each element
    maxTotalError: 0.01, // 1% total error (absolute sum of element errors)
  },
);

console.log(result);
