The instant invention involves the use of a combination of preparatory steps in conjunction with mass spectroscopy and time-of-flight detection procedures to maximize the diversity of biopolymers which are verifiable within a particular sample. The cohort of biopolymers verified within such a sample is...

Stephen T.Semegen, inEncyclopedia of Physical Science and Technology (Third Edition), 2003 V.B.1Molecular Weight Since rubber is a high-molecular-weight substance, ranges of values exist. Viscosity measurements of the dry rubber in shear are commonly used for relative assessment ofmolecular weight...
