The phrase "at the minimum concentration" is correct and usable in written English.
It can be used in scientific or technical contexts to refer to the lowest level of concentration of a substance in a solution or mixture.
Example: "The experiment was conducted at the minimum concentration of the chemical to observe its effects on the reaction rate."
Alternatives: "at the lowest concentration" or "at the least concentration".
The oxosteroids 17-α-methyltestosterone, nandrolone, boldenone, 17-α-Trenbolone, fluoxymesterolone, mesterolone and bolasterone were identified in human urine at the minimum concentration level recommended by the world anti-doping agency, 2 ng/mL.
Furthermore, Mitchell said: "If you look at the minimum concentration for which a significant negative impact on bees has been found, then 48% of our samples exceed this level". The researchers said these impacts include damage to learning, behaviour and colony success.
O. majorana-mediated SNPs showed better result against E. coli at the minimum concentration of 25 µg/ml, whereas -mediated SNPs were good against B. subtilis.
Our analysis indicated that RL7-11 and RL-STD reached the maximum E24 index of 100% at the minimum concentration of 1.2 g/l, whereas SDS reached the maximum E24 index of 74% at the minimum concentration of 5 g/l (Fig. 5b).
This protein, on sequencing found, to be homologous to bikunin, inhibited crystal adhesion at the minimum concentration of 10 ng/mL, and completely blocked it at 200 ng/mL.
Similarly, the LOQ on the Cp scale was estimated by the upper one-sided 95% confidence interval of the fitted (linear) model at the inverse prediction of ymin or at the minimum concentration fulfilling the linear range criteria if the inverse prediction of ymin was less than the lower linear range limit (on the concentration scale).
To quantify this effect, we defined the lower limit of detection sensitivity as the minimum concentration at which an observer could correctly identify the original object from the reconstructed image.
a The MIC defined as the minimum concentration of antibiotic at which growth was completely inhibited while the MBC defined as the minimum concentration at which 99.9% of bacteria was killed.
At 4°C, the minimum concentration of P22sTsp resulting in detectable cell agglutination (minimum agglutination concentration) was 149 ng/ml (Figure 1).
It appears that cryoprotectant solutions that are composed to be at the minimum concentrations needed for vitrification at moderate cooling rates are toxic in direct proportion to the average strength of water hydrogen bonding by the polar groups on the permeating cryoprotectants in the solution.
Multivariate data analysis revealed that at pH 5 the minimum concentration of sorbic acid necessary for a tenfold decrease of viable spores ranges between 0.08% and 0.10% exhibiting only minor dependence on the cosolvents concentration.
