The phrase "a better quantification of" is correct and usable in written English.
It can be used when discussing improvements in measurement or assessment of a particular variable or phenomenon.
Example: "The new model provides a better quantification of the environmental impact of the project."
Alternatives: "an improved measurement of" or "a more accurate assessment of".
Since March 14, 40 more ashmeters have been deployed around Tungurahua volcano that will allow a better quantification of Tungurahua ash emissions (Bernard et al., in preparation).
However, the inclusion of kinetic PET data will likely give rise to a better quantification of VAP-1 expression in local tissues.
The model simulated the contributions of pre-event and event waters during flood events and allowed a better quantification of the available resource.
The comparative study based on a better quantification of the accuracy and precision of hydrological modelling predictions yields a better understanding for the potential improvement of model deficiencies.
A better quantification of uncertainties should provide better decisions, which often translate into optimal use and economic value of the forecasts.
These investigations are designed to achieve a better quantification of supported 226Ra activities in the separated samples, enabling the use of excess 226Ra (226Raex) in marine barite as a tool for dating Holocene sediments.
Moreover, the reconstruction of the absorption and scattering properties of the sample allows a better quantification and localization of the fluorescence signal.
Also, they argue that a better quantification and resolution of the cap formation process (which was my main suggestion to possibly achieve a conceptual understanding of the symmetry breaking process) is hindered by phototoxicity.
For a better quantification with 3D optical profilometry, a time-of-flight secondary ion mass spectrometry (ToF-SIMS) was used for the experiments.
However, because 177Lu can only be imaged using SPECT cameras, a PET equivalent such as 89Zr-labelled I253A/H310A might be a better alternative and may allow better quantification of tumour uptake and saturability in vivo.
Iyer et al. (2012) developed a reaction-transport model that enables better quantification of the amount and depth at which hydration occurs in an incoming oceanic plate due to normal faulting caused by the bending force.
