title: Some observations on a new type of point average molecular weight.
abstract: A new type of (reduced) point average molecular weight, A*, is described. Several interesting properties are developed: (i) A* (cell base) = reduced weight average molecular weight over the whole cell, Aow; (ii) A* (meniscus) = Aw (meniscus); (iii) A* (zero concentration) = reduced number average molecular weight, An (meniscus). In addition, its usefulness in extracting the meniscus concentration, J(a), and in examining heterogeneous systems such as mucus glycoproteins, are discussed. The evaluation and application of A* requires only simple computational facilities, without the use for large-scale multiple data acquisition and recycling techniques.
