pH

BACKGROUND
The test for pH is measure the acidity or basicity of an aqueous solution.  The pH of water at 25°C is approximately 7.0.  Solutions with a pH of greater than 7.0 are said to be basic and solutions with a pH of less than 7.0 are acidic.

OUR METHODOLOGY
DYNALABS test pH using a standardized potentiometric instrument according to USP <791>.  For samples with a monograph in the USP, DYNALABS will use the specification define in the monograph, unless otherwise instructed by the customer.  For sample that do not have monographs DYNALABS uses the customer defined specification, and in the absence of a customer defined specification will use a specification of “Report Result”.
