Cementation | sedimentary rock | Britannica

Cementation, in geology, hardening and welding of clastic sediments (those formed from preexisting rock fragments) by the precipitation of mineral matter in the pore spac It is the last stage in the formation of a sedimentary rock The cement forms an integral and important part of the rock.

Elution - an overview | ScienceDirect Topics

An example of elution by changing pH is the elution of antibodies from immobilized protein A or protein G, yet because the affinity of proteinA/G to antibodies is very strong, with K a in the 10 8 M − 1 range, a combination of different elution conditions may be required for maximum antibody release In many cases, affinity requires proper .
