The phrase "a concentration increase" is correct and usable in written English.
It can be used in contexts related to science, chemistry, or any field discussing changes in concentration levels of substances or elements.
Example: "The experiment showed a concentration increase of the solute after the reaction was completed."
Alternatives: "an increase in concentration" or "a rise in concentration."
Their competitive interactions with metal ions to HSA revealed that the participation of Mg2+ ion in compound 7d HSA association could result in a concentration increase of free compound 7d.
Furthermore, a concentration increase by 16 folds (from 0.5 to 8 wt%) has caused only a modest increase in size which again falls within the experimental error.
The elements Mn, P, Cr, Ni, Mo, and Ti, which show a concentration increase in the sandstones after the experiments, might originate from the pipe material of the apparatus.
Results derived from stress strain measurements as depicted in Table 2 shows that an increase in the concentration of EGDMA results in a concentration increase Young's and Shear modulus.
We recall that 6 mL of 250 g L−1 NaNO3 was added to each PBR on day 4 this corresponds to a concentration increase of ~ 82.35 mg L−1 NO3-N for each vessel (indicated in the table using the notation '+ 82.35' on day 4, assuming there was 3 L of liquid in each PBR).
As a large amount of NO3-N was consumed in the MX, MX-N, and MX-C flasks, the nitrogen content in some of these flasks (MX and MX-C) were further enhanced at the beginning of Phase II (by adding 30 mL of 250 g L−1 NaNO3, corresponding to a concentration increase of about 411.8 mg L−1 NO3-N in each flask).
The diurnal change of amplitude of sea surface temperature decreases from 1.5° to 0° after the week-long prevailing northwest monsoon wind with the maximum gust more than 20 m/s while the observed surface salinity and chlorophyll-a concentration increase from 34.1 to 34.37 and from 0.05 to 0.14 mg/m3, respectively.
We assumed an additive genetic model (i.e., fetuin-A concentration increasing linearly with each additional minor allele of the genotypes).
When the Con A-containing buffer was added to the gel-modified FET, positive shifts of the VT were observed and increased as the Con A concentration increased.
During the end of July chlorophyll-a concentrations increased dramatically, first in high resource enclosures and then in low resource enclosures (Fig. 4).
