at different concentration vs in different concentration

Both "at different concentration" and "in different concentration" are commonly used phrases in English. They are both correct, but the choice between them depends on the context in which they are used. "At different concentration" is typically used when referring to specific points or levels of concentration, while "in different concentration" is used when discussing the overall composition or mixture of substances.

at different concentration

This phrase is correct and commonly used in English.

This phrase is used when referring to specific points or levels of concentration. It indicates the particular concentration at which something is being measured or observed.

Examples:

The enzyme activity was measured at different concentrations of the substrate.
The drug showed varying effects at different concentrations.

in different concentration

This phrase is correct and commonly used in English.

This phrase is used when discussing the overall composition or mixture of substances. It indicates that there are variations in the concentration of a substance within a mixture.

Examples:

The samples were prepared in different concentrations of the reagent.
The solution was found to be stable in different concentrations of the solvent.
