Specific Gravity of Coarse Aggregates: Its Importance ...

2021-3-5 · In the aggregates, some of the pores are permeable, whereas others are impermeable. Therefore, two types of specific gravities are defined: one is the absolute specific gravity, and second is the apparent specific gravity. In the determination of true or absolute specific gravity, both the permeable and impermeable voids are excluded.

Challenges in the Determination of Protein

Most analytical approaches used for the determination of low-molecular-weight noncovalent aggregates in protein pharmaceuticals suffer from important limitations. This first part of this two-part column series discusses those limitations. Part II will present a viable analytical approach that offers, in our opinion, the best solution for analyzing these aggregates. The intent of this column is ...
