. Such variability is a key contributor to many pharmaceutical companies' need for a "hidden factory, " or an extensive non-value-adding infrastructure, to ensure product quality and safety (Figure 1). Chromatography process variability starts with buffer or solution make-up; effects of that variability ripple
Selection Factors for Seals

Optimizing the Use of Aircraft Deicing and Anti-Icing Fluids
Use of 10°C Type I buffer: Standard deicing fluid con- centrations (typically 50% water/50% glycol) have been employed by the industry, despite the fact that Type I deicing holdover times are based on 18°F (10°C) buffer fluids .

New pH-Buffered Low-Polymer Borate-Crosslinked Fluids
Laboratory conductivity tests show that these pH- buffered fluids , utilizing reduced polymer loadings, produce retained conductivity values of 10 to 25% (absolute) higher than alternative conventional borate-crosslinked fluids incorporating higher polymer loadings.
Metasomatism and the Chemical Transformation of Rock
The composition of most crustal fluids is effectively buffered for a wide range of components by interactions with minerals in the host rock (Hanor 1994; Yardley 2005); buffered fluids are saturated solutions of common host rocks.
