"ranges of concentration" is correct and can be used in written English.
For example, "The study examined the ranges of concentration of pollutants in the river."
Here, the circuit was designed to obtain high S/N signals and a relation function with a high multiple correlation coefficient of 0.998 was obtained to adapt the wide ranges of concentration 0∼20 wt% and temperature 10∼80°C on measuring electrolyte-solution concentration.
The authors of the present paper therefore developed a new concept without restrictions and applicable in all ranges of concentration, particle size and pipe diameter.
A mechanism developed for sodium sulfite oxidation was found to describe the experimental results for wide ranges of concentration of the reactants.
Aggregation behavior of hydrophobically modified ethyleneglycol oligomer, poly ethylene glycol) monododecyl ether (C12E25), in aqueous solution has been studied in wide ranges of concentration and temperature by means of light scattering, X-ray scattering, and linear-viscoelastic measurements.
Additionally, a very good linear response in the ranges of concentration tested (0.94 ppb to 3.75 ppb, R2=0.9975 and 3.75 ppb to 30 ppb, R2=0.9991) was obtained, complying perfectly with the acceptable arsenic concentration limits defined by the World Health Organization for drinking water samples (i.e. 10 ppb).
The method was thoroughly validated over two ranges of concentration of 2 100 ng mL−1 and 100 5000 ng mL−1 (r > 0.999) which produced a good intra-day and inter-day accuracy and precision.
The proposed classification along with ranges of concentrations of these parameters is given in Table 1.
Ranges of concentrations of measured phthalates are also presented.
"I have such a narrow range of concentration".
To test this possibility, hydrogen peroxide (H2O2) was used as an exogenous form of ROS in a range of concentration used in previous reports.
Intracellular protein content exhibits 9-orders of magnitude in range of concentration.
