Sentence examples for mass concentration using from inspiring English sources

The instrument determines volume (or mass) concentration using a volume conversion factor Cv.

The SA of the final product was also determined with LC/MS by measuring the [19F]CFT mass concentration using the same reference as was used with analytical HPLC.

Optical density was converted to dry cell mass concentration using a standard curve determined before.

We obtained particle counts using a condensation particle counter (model 3022A; TSI, Shoreview, MN), and we calculated mass concentration using idealized particle density (1.5 g/cm).

The exposure mass concentration used in our study, 50 μg/m, is relevant to concentrations encountered on or near roadways in urban environments, where the fine particle mass can exceed 100 μg/m (HEI Panel on the Health Effects of Traffic-Related Air Pollution 2010).

This work expands on previously published measurements of PM mass and chemistry by examining the sources of fine and coarse particles and the relative contribution of each to ambient PM mass concentrations using the Positive Matrix Factorization receptor model (Clements et al., 2014).

The set of spectra was calculated from the size-segmented aerosol mass concentration measured using the Micro-Orifice Uniform Deposit Impactor (MOUDI) onboard a research vessel; the marine aerosol sampling performed during ACE Asia 2001 is summarized by Mochida et al. (2007).

The amount of dye adsorbed per unit biosorbent (mg dye/g of biosorbent) was calculated according to a mass balance on the dye concentration using Eq. (1): q_{text{e}} = frac{{(C_{0} - C_{text{e}} ),V}}{m} (1 where C0 is the initial dye concentration (mg L−1), Ce the equilibrium dye concentration in solution (mg L−1), V the volume of the solution (L), and m is the mass of the biosorbent in g.

The amount of dye adsorbed per unit PLP (mg dye per g biosorbent) was calculated according to a mass balance on the dye concentration using Eq. (1): q_{rm {e}} = frac{(C_{rm {i}} -C_{rm {e}});V}{m} (1 where C i is the initial dye concentration (mg L−1), Ce is the equilibrium dye concentration in solution (mg L−1), V is the volume of the solution (L), and m is the mass of the biosorbent (g).

Furthermore, gravimetrically determined cell mass concentration was used together with the fluorescence spectra for calibration and validation of multivariate partial least squares (PLS) regression models.

The results suggested that the contribution to indoor PM2.5 mass concentrations from using gas for cooking was negligible over the 6- or 24-hr periods relevant to this study; i.e. PM2.5 in homes using gas from cooking could not be distinguished reliably from background [ 22].
