BRIEFING

 〈1785〉 Osmolality and Osmolarity—Practical Considerations. It is proposed to add this new chapter as a companion to Osmolality and Osmolarity 〈785〉, which is being revised in this issue of PF. This new chapter makes recommendations on how to assess osmolality or osmolarity measurements for complex samples such as, but not restricted to, samples with high protein content or high viscosity that may be difficult to freeze under normal testing conditions.
