If the specific optical rotation specification for a sample is
-48 to -51 deg, which is the Upper Specification Limit? Is it -48 or -51?
-48 is a larger number than -51.
To determine the Upper Specification Limit (USL), we need to consider the range given for the specific optical rotation specification.
In this case, the specific optical rotation specification range is -48 to -51 degrees. The USL represents the maximum allowed value within this range. Since -51 degrees is the lower value in the range and -48 degrees is the higher value, the USL is -48 degrees.
Therefore, the Upper Specification Limit is -48 degrees.
