Can a laboratory reproduce the stated physical measurement without proprietary interpretive software?
The charge is measured on every production run, and the measurement can be repeated on any filter, upon request.
The polarity is a positive electric charge at rest, and it is measured as surface charge density, in nanocoulombs per square centimetre. The coulomb is the unit of electric charge, and the National Institute of Standards and Technology gives the quantity the coulomb measures as “electric charge, amount of electricity.” That is a physical quantity in a published unit, and the company publishes no software and no interpretive step. The company publishes no measurement procedure, no instrument record and no uncertainty budget.
The company states no value, so a laboratory that measures a filter is measuring it, not reproducing a published figure.
