The terms "maximum assay" and "minimum assay" are commonly used in the context of chemical analysis, specifically in relation to the purity determination of a substance.

The maximum assay refers to the highest percentage of the target compound present in a given sample. It indicates the highest level of purity that can be achieved for that substance.

The minimum assay, on the other hand, refers to the lowest percentage of the target compound that must be present in a sample to meet certain specifications or standards. It represents the minimum acceptable level of purity for the substance to be considered pure or of sufficient quality.

To determine the maximum assay and minimum assay of a substance, you would typically perform a quantitative analysis using an appropriate analytical method or technique. This can be achieved through various methods such as chromatography, spectroscopy, or titration, depending on the nature of the compound being analyzed.

Here is a step-by-step breakdown of how you could determine the maximum and minimum assay:

1. Prepare a representative sample of the substance to be analyzed. This typically involves taking a small portion of the substance that is representative of the whole.

2. Select an appropriate analytical method or technique based on the properties of the substance. This could involve techniques such as high-performance liquid chromatography (HPLC), gas chromatography (GC), or UV-visible spectroscopy.

3. Calibrate the analytical method using standards of known purity. This step is crucial for determining the accuracy and reliability of the method being used.

4. Perform the analysis using the prepared sample and the calibrated analytical method. This involves injecting the sample into the instrument or performing the necessary measurements according to the chosen method.

5. Calculate the assay value based on the obtained results. This can be done by comparing the peak area or height of the target compound in the sample to that of the standard, or by using a calibration curve obtained from the standards.

6. Repeat the analysis multiple times to ensure precision and obtain a reliable average value.

By following these steps, you can determine both the maximum and minimum assay values for a given substance, which provide important information about its purity and quality.
