The phrase "a limited selectivity" is correct and usable in written English.
It can be used to describe a situation or system that has a restricted ability to choose or differentiate among options.
Example: "The experiment demonstrated a limited selectivity in the chemical reactions, leading to unexpected byproducts."
Alternatives: "restricted selectivity" or "narrow selectivity".
In order to gain sufficiently high fragment ion intensities, limited selectivity of precursor selection has to be addressed (e.g., isolation width = 2 or 3 u).
The phosphate dolomite separation has a limited separation selectivity using conventional flotation.
Limited selectivity of OFDM/SC-OFDM receiver-in a case when there is no user data transmission in the uplink (only the control channel is present), the middle part of the UL component carrier is empty, and only the resource blocks at the border convey useful data.
Due to low dispersion of CNTs into solvents and limited selectivity of CNTs and oxidized CNTs for SPE, a common technique is chemical functionalization which is used relatively often to generate functional groups on the surface of CNTs (Liu et al. 2008).
However, the limited selectivity of the OXR antagonists available has prevented a full elucidation of the relative neuro-functional contribution of each receptor sub-type on specific physiological functions of potential therapeutic relevance.
A drawback of the dosimeter used in this study is the limited selectivity to differentiate between the three frequency ranges.
Given the limited selectivity of current small molecule tyrosine kinase inhibitors, studies of more selective antagonists are underway.
However, this method offers only limited selectivity since most chemical interfaces based on reversible chemical interaction are not very selective [9] [13].
The limited selectivity of NVP-AAM077 at higher concentrations prevented us from reaching a definitive conclusion about the contribution of GluN2A-containing NMDAR to induction of LTP in either genotype.
