Analytical chemistry in ESM

Molarity, ppb and dose types, with a contaminated batch the rules find

type: molarity · ppb · doseRate

This is an analytical chemistry sheet with molarity, parts-per-billion and dose-rate types, and a contaminated batch that the rules find. It shows domain units and inline rules catching a real problem in scientific data.

Loading a live grid…

This is the ES module version. The grid is imported straight from a CDN as a module, the same configuration as the vanilla tab without a global script tag, so it drops into any bundler or a bare module script.
