[27] You will discover requirements known as 'release requirements' that samples tested will have to satisfy statistically, both equally as personal values and as ordinary of The complete.[28][29] One particular such standards is the parameter "Q", and that is a percentage worth denoting the quantity of dissolved Energetic component throughout the monograph of the sample solution. When the First sample Investigation, often called S1 or phase 1 testing fails to satisfy the satisfactory price for Q, then added testing often known as stage 2 and three testing is needed.
