In this article, we will discuss various methods to determine the concentration of a solution and provide step-by-step instructions for each method. Methods to Calculate Concentration. 1. Mass by ...

IT is becoming customary, in the descriptions of histochemical methods, to express the concentration of solutions in terms not of percentage but of molarity. Thus, in one method, it is stated that ...

A mathematical model of Wu et al. [J. Membr. Sci 254 (2005) 119-127] of a cationic glucose-sensitive membrane is discussed. The model involves the system of non-linear steady-state reaction-diffusion ...

An approximate analytical expression of concentration profiles of n-butanol in the biofilm phase and gas phase has been derived using the homotopy perturbation method and hyperbolic function method ...

The critical coagulation concentration of a colloidal dispersion for the case of a general electrolyte solution is estimated under the conditions of constant surface potential. By combination of the ...

The inexact Newton–Kleinman method is an iterative scheme for numerically solving large-scale algebraic Riccati equations. At each iteration, the approximate solution of a Lyapunov linear equation is ...

Among such methods, a new approach of homotopy perturbation method is applied to solve the non-linear differential equations Eqns. (11) and (12). The focal point of this method is that it resulted in ...

Glucose plays an important role in biological fermentation and biosensing. Therefore, it is very important to detect the concentration of glucose aqueous solution quickly and accurately. A novel ...

Simplified methods are described for the measurement of human plasma renin "concentration" (PRC) and "activity" (PRA) based on the denaturation of renin substrate in which separation and concentration ...
