ORDER OF REACTION - PharmaQuesT

When the reaction rate is independent of concentration of the reacting substance, it depends on the zero power of the reactant and therefore is zero order reaction. In this type of reaction, the limiting factor is something other than concentration, for example, solubility or absorption of light in certain photochemical reactions.

PHARMAQUEST (c) This method maintains the procedure of the finding evaluate the reliability of the sample. Disadvantages (a) This technique of sampling cannot be used for a large sample.It is applicable only for small sample. (b) This technique is time consuming, costly, and requires more competition.(c) Its planning and administration is more complicated.

Stability:- Basic Concepts and Objectives

STRESS TESTING–FORCED DEGRADATION (API) Studies undertaken to elucidate the intrinsic stability of the API. Such testing is part of the development strategy and is normally carried out under more severe conditions than those used for accelerated testing. To identify potential degradants (degradation pathways) of the API and assess if they can

General Properties of Polyvinyl Chloride Pipe

CORROSION, PERMEATION, AND CHEMICAL RESISTANCE_____ PVC and PVCO pipes are resistant to almost all types of corrosion—both chemical and electrochemical—that are experienced in underground piping systems. Because PVC is a nonconductor, galvanic and electrochemical effects are nonexistent in PVC piping systems.
