The phrase "a different concentration of" is correct and usable in written English.
It can be used when discussing variations in the amount or strength of a substance in a particular context, such as chemistry or nutrition.
Example: "The experiment required a different concentration of the solution to observe the effects on the reaction rate."
Alternatives: "a varying level of" or "a distinct amount of".
