Osmotic concentration - Wikipedia
The unit of osmotic concentration is the osmole. This is a non-SI unit of measurement that defines the number of moles of solute that contribute to the osmotic pressure of a solution. A milliosmole (mOsm) is 1/1,000 of an osmole. A microosmole (μOsm) (also spelled micro-osmole) is 1/1,000,000 of an osmole.

克分子渗透压浓度 - 百度百科
克分子渗透压浓度 osmolality，osmolarity是物理学术语， 为表示某溶液的渗透压，有时使用与该溶液具有等渗的非电解质溶液的克分子浓度，称此为克分子渗透压浓度，以渗透克分子（osmole，Osm），或毫渗透克分子（m osmole， m Osm）来表示。
Osmolarity and Osmolality - an overview | ScienceDirect Topics
2010年11月1日 · An osmole is 1 mole of any fully dissociated substance dissolved in water. Osmolality is the concentration of osmoles in a mass of solvent. In biologic systems, osmolality is expressed as mOsm/kg of water and can be measured using an osmometer.
等渗溶液和等张溶液的区别 - 知乎 - 知乎专栏
2023年4月11日 · osmolarity 是一种浓度，表示每升水中有多少 osm 的溶质。 osmolarity 可以用 渗压计 测量。 如果两种溶液的 osmolarity（或 重量克分子浓度osmolality） 相等，就说他们是等渗的。 如果我们只提到某一种溶液是等渗的，一般默认它和血浆是等渗的。 tonicity 描述的是一种行为，是定性的。 把细胞放到溶液中，张性衡量的是溶液对细胞体积会产生怎样的影响。 低张（hypotonic）溶液中的细胞会吸水膨胀，高张（hypertonic）溶液中的细胞会失水皱缩。 …
克分子渗透压浓度 osmolality，osmolarity_生物行
2007年7月24日 · Osmolarity is a measure of the osmotic pressure exerted by a solution across a perfect semi-permeable membrane (one which allows free passage of water and completely prevents movement of solute) compared to pure water. Osmolarity is dependent on the number of particles in solution but independent of the nature of the particles.
Osmole | definition of osmole by Medical dictionary
osmole The standard unit of osmotic pressure. The osmole is equal to the molecular weight of the dissolved substance expressed in grams divided by the number of particles or IONS into which each molecule of the substance dissociates in solution.
Basic concepts and practical equations on osmolality ... - PubMed
Osmolality is milliosmoles of solutes per one kilogram (or liter) of water of solution (plasma) and is calculated by osmolarity divided to plasma water. The osmolal concentration is corrected to osmolal activity by using the osmotic coefficient, φ.
Osmolarity | Definition, Formula & Osmolarity vs. Osmolality
2019年5月24日 · An osmole (Osmol) is basically 1 mol particles that contribute to generating Osmotic Pressure of a solution. For example, when NaCl dissolves in water it completely dissociates in water and forms Na + ions and Cl – ions. Thus, each one mole of NaCl becomes two osmoles in solution after dissociation: one mole of Na + ion and one mole of Cl ...
