Define the following terms

1 Maximum assay
2 Percentage assay

Percentage assay is the ratio of purities to impurities expressed as percentage

1. Maximum assay:

To define the term "maximum assay," we need to understand two components: "assay" and "maximum."

Assay refers to the analysis or measurement of the composition or purity of a substance, typically conducted in a laboratory setting. It involves determining the quantity or proportion of a particular component in a sample. Assays are commonly used in fields such as chemistry, pharmaceuticals, and biology.

Maximum, on the other hand, refers to the highest possible value or limit that can be attained.

Combining these two terms, a maximum assay refers to the highest or maximum level or amount of a specific component that can be measured or detected in a sample during an assay. It represents the upper limit or concentration of the component that can be identified using the particular assay method.

2. Percentage assay:
The term "percentage assay" also involves two concepts: "assay" and "percentage."

As discussed earlier, an assay involves measuring the quantity or proportion of a particular component in a sample.

Percentage, in this context, represents a fraction or proportion of one quantity in relation to a whole, expressed as a fraction of 100.

Putting it together, percentage assay refers to the proportion or percentage of a specific component in a sample, expressed as a fraction of the whole, usually represented as a percentage value. It provides information about the purity, concentration, or amount of the component in relation to the entire sample.
