The phrase "a sufficiently large quantity" is correct and usable in written English.
It can be used when discussing the adequacy of a certain amount of something in various contexts, such as scientific, economic, or general discussions.
Example: "In order to conduct the experiment successfully, we need to ensure that we have a sufficiently large quantity of the reagent."
Alternatives: "an adequate amount" or "a considerable quantity".
Legislation is justified even for a chemical preparation with a low hazard, if it can pose a risk to the environment through being released in sufficiently large quantities.
Despite the anticoccidial activity observed for natural products, the elevated cost of farming and production required to obtain sufficiently large quantities make their use impractical as a strategy to control coccidiosis in large population of birds.
Despite the anticoccidial activity observed for natural products, the elevated cost of farming and the production required to obtain sufficiently large quantities of extracts renders their use as a strategy to control coccidiosis in large population of birds difficult.
Heavy water was not only less effective than graphite but also far more difficult to obtain in sufficiently large quantities, leaving the Nazis dependent on steady supplies from the Norsk Hydro plant in Norway.
"The likelihood of fish absorbing sufficiently large quantities of radioactive fallout from the ocean is negligible," Lam says, "except for larger fish, who live long enough to accumulate large amounts".
At present, our knowledge of these processes on the molecular and cellular level is limited, since studies on HSCs are hampered by their low abundance in hematopoietic organs and are thus difficult to access in sufficiently large quantities for direct studies.
In case you wondered, Professor Brewer reported that the "overwhelmingly strong assumption that in common usage, a sufficient plurality is interpreted as a sufficiently large number or quantity or profusion".
Any finite number of lives in population A can therefore be outweighed by a sufficiently large number of lives in Z because the gain in the quantity of lower values outweighs the loss of certain higher values.
Continuum theory may be applied when there is a sufficiently large sample size to ensure that statistical variation of material quantities, such as density, is small.
