The preanalytical phase includes a set of processes that are difficult to define because they take place in different places and at different times. Classically, the preanalytical phase included all processes from the time a laboratory request is made by a physician until the...
In chemistry, concentration refers to the amount of a substance in a defined space. Another definition is that concentration is the ratio ofsolutein a solution to eithersolventor totalsolution. Concentration is usually expressed in terms ofmassper unitvolume. However, the solute concentration may al...
Adsorption is a surface phenomenon in which particles or molecules bind to the top layer of material. Absorption, on the other hand, goes deeper, involving the entire volume of the absorbent. Absorption is the filling of pores or holes in a substance. Characteristics of Adsorbents Typically, ads...
