Error Analysis of Intrinsic Viscosity Measurements
The intrinsic viscosity of polymer solutions is widely used for characterizing the molecular sizes of polymers. The experimental procedure is very involved, and therefore a variety of precautions needs to be observed to eliminate errors. In this paper, a hypothetical case is discussed to demonstrate that the analysis of data can detect the absence or presence of different kinds of errors in the experimental measurements. It is shown that a systematic or constant error in the concentration measurement is the only error that is not reflected anywhere in the analysis and still leads to inaccurate results. Therefore, it is very important to eliminate this error through the automation of instruments.
