Sqmin Minimum Weighing - Sartorius Cubis MSU116P User Manual

SQmin Minimum Weighing

Purpose: This application is used to compare the measured weight value directly with the
defined minimum sample quantity (SQmin = sample quantity minimum). This
ensures that weighing results are within tolerances defined by your quality assur-
ance system. This fulfils the requirements of the United States Pharmacopeia (USP).
According to USP guidelines, the measurement uncertainty can be a max. of 0.1%
in terms of the initial weight when weighing substances for quantitative analyses.
Requirements: The balance must be set up by a service technician to be able to use the SQmin
function. The technician will determine the permitted minimum sample quantity
and set this on your balance using your QA system's guidelines. He will document
this setting via a "Weighing module test as per USP" certificate in which the mea-
surements and min. sample quantity are logged. The SQmin function ensures that
the weighing results correspond to USP guidelines.
Combination options: Mass unit conversion, second tare memory, individual identifiers (DKD measure-
ment uncertainty)
