in determined concentrations vs at determined concentrations

Both 'in determined concentrations' and 'at determined concentrations' are correct, but they are used in different contexts. 'In determined concentrations' is used when referring to the specific concentrations of substances, while 'at determined concentrations' is used when specifying the point or level at which something occurs.

in determined concentrations

This phrase is correct and commonly used when referring to specific concentrations of substances.

This phrase is used to indicate the exact concentrations of substances being discussed. It is commonly used in scientific contexts.

Examples:

  • The drug is effective in determined concentrations.
  • The enzyme activity was measured in determined concentrations of the substrate.
  • The pollutants were found in determined concentrations in the water sample.
  • determined concentrations of the test substance in 1-octanol and water as a function of time
  • Only the total element concentration is determined.
  • Plasma bimatoprost and timolol concentrations were determined in a crossover study comparing the monotherapy treatments to GANFORT treatment in healthy subjects.
  • The surface tension shall be determined at the highest concentration.
  • In vitro plasma protein binding studies determined that the mean concentration of the free drug was 74%.
  • DOC and/or COD concentrations are determined at least in duplicate in the samples according to 1.6.2 above.
  • The TVB-N concentration is determined by titration of the absorbed bases.
  • The dilution ratio is determined from the concentrations of tracer gases, such as CO2 or NOx, naturally occurring in the engine exhaust.
  • The water solubility is determined when the mass concentration of the eluate is constant.
  • Where stricter, the generic or specific concentration limits determined in accordance with Article 10 of Regulation (EC) No 1272/2008 shall prevail to the cut-off limit value of 0,010 % w/w (in terms of wet weight) mentioned above.
  • Specific concentration limits determined in accordance with Article 10 of Regulation (EC) No 1272/2008 shall apply in case it is lower than 0,10 %.
  • Specific concentration limits determined in accordance with Article 10 of Regulation (EC) No 1272/2008 shall apply in case it is lower than 0,1 %.
  • Applicable to membrane cell plants with brine recirculation, if the brine purge rate is determined by the sulphate concentration.
  • The quantities of pollutants are determined from the sample concentrations, corrected for the pollutant content of the ambient air and the totalised flow over the test period.
  • As a rule of thumb, the method limit of quantification can be determined as the concentration in water or 1-octanol that produces a signal to noise ratio of ten.
  • When such standards are not available, or where relevant to the manufacturing process, at least the following particulars shall be described and their concentrations determined:
  • On the basis of the parameters of the analytical method and the expected concentrations, an approximate sample size required for an accurate determination of the compound concentration is determined.
  • The DOC (or COD) concentrations are measured in the effluents, or the substance concentrations are determined by specific analysis.
  • The flow of carbon at various sampling points in the emissions and particulate sampling systems is determined from the CO2 concentrations and gas flow rates at those points.
  • For the calculation of the total uncertainty to be used in Section 2.2, hourly N2O concentrations as determined pursuant to Section 2.3 shall be used.

Alternatives:

  • in specific concentrations
  • in defined concentrations
  • in established concentrations
  • in fixed concentrations
  • in known concentrations

at determined concentrations

This phrase is correct and commonly used when specifying the point or level at which something occurs.

This phrase is used to indicate the specific concentration level at which something happens or is measured. It is commonly used in various contexts.

Examples:

  • The reaction rate peaks at determined concentrations of the reactants.
  • The color change occurs at determined concentrations of the indicator.
  • The precipitation forms at determined concentrations of the solute.
  • The surface tension shall be determined at the highest concentration.
  • determined concentrations of the test substance in 1-octanol and water as a function of time
  • Only the total element concentration is determined.
