Quality checks to run before any mixing analysis.

A mixing calculation cannot tell you that an analysis is wrong – it will happily apportion a charge-imbalanced sample among your end-members and return confident numbers. These checks are the cheapest protection available, and they belong at the top of every notebook.

Functions

charge_balance_error	Charge balance error in percent, per sample.
charge_balance_report	Per-sample charge balance with a pass/fail flag.
detection_limit_report	Count values at or below the detection limit, per species.
ec_check	Compare measured EC with EC estimated from the ion sum.
ec_from_ions	Estimate electrical conductivity (uS/cm) from the cation sum.
missing_data_report	Count missing values per species, with the count of complete samples.
