concentration of buffer effects in buffer strength
To calculate the pH of a buffer solution, you can use the Henderson-Hasselbalch equation, which is pH pKa log(A-/HA), where pKa is the negative logarithm of the acid dissociation constant, A- is the concentration of the conjugate base, and HA is the concentration of the weak acid in the buffer solution.
In chemistry, the spike method, more often called the addition method, is used to find the concentration of an analyte in a complex matrix. Examples of such matrices would be soil samples or biological fluids.
One common method to determine the concentration of an acid is titration. In an acid-base titration, a solution of known concentration (titrant) is added to the acid solution until the reaction is complete, as indicated by a color change with an indicator or a pH meter. The volume of titrant used is then used to calculate the concentration of the acid.
The method you are referring to is called titration. Titration involves slowly adding a solution of known concentration (titrant) to a solution of unknown concentration (analyte) until the reaction is complete, allowing the determination of the analyte's concentration.
Titration is a quantitative method used to determine the concentration of a substance in a sample. It involves slowly adding a reagent of known concentration to the solution being analyzed until a specific endpoint is reached, allowing for the calculation of the unknown concentration.

pH is regulated generally in the stomach, when food is broken down. Acids are introduced to dissolve food and i think then bile is introduced to neutralize the acid, so you don't get eaten from the inside out. Which would be unfortunate.

Titration
Sensitivity is the smallest change in concentration of the analyze that can be detected by using that method. This is the slope of the calibration curve. Detection limit is the lowest concentration that can be detected by the particular method.

I don't know how to make the solution below. Low salt buffer: 10 mM phosphate buffer, 10 mM NaCl, pH 7.4. Could you tell me the method in detail?

The Bradford method involves a chemical test. It is used by scientists to determine the concentration of proteins in a solution.
