What does isotopically mean?
Isotopically is an adverb meaning in a way that involves isotopes, the versions of an element that have the same number of protons but different numbers of neutrons. It is used especially when scientists are distinguishing, tracing, or enriching material according to these differences in nuclear composition. For example, carbon atoms can be isotopically labeled so that researchers can follow where particular carbon samples originate or how they move through an organism or environment. The adverb is closely associated with laboratory and field methods in chemistry, geology, biology, and related sciences. In nontechnical contexts it may occasionally describe any contrast based on precise variations among similar things, but its principal use is scientific. Isotopically also reflects the broader idea that elements can share their basic chemical identity while possessing subtly different isotopic signatures that make them traceable.
adverbIn a manner involving isotopes or the distinctive nuclear or isotopic properties of atoms. It is especially used to describe material that has been characterized, labeled, enriched, or traced according to its isotopic composition.
- In a manner that involves or distinguishes atoms according to their isotope composition or isotopic properties.
"The researchers isotopically labeled the samples to trace how carbon moved through the ecosystem."
"The team isotopically enriched the water so that the contribution from each source could be measured."
"Because the compounds are isotopically distinct, the spectrometer can determine their relative abundance."
Isotopically labeled molecules can reveal the hidden journey of carbon, oxygen, or nitrogen through nature.

Where does isotopically come from?
The underlying word “isotope” was coined in the early 20th century from Greek iso, meaning “equal,” and topos, meaning “place,” reflecting the initial proposal that such atoms occupied equivalent places in the periodic table. The adjective “isotopic” and the adverb “isotopically” were formed from this stem with the suffixes -ic and -ly. Related scientific vocabulary includes “isotopy,” referring to the study or phenomenon of isotopes, and “isotope” itself.

How isotopically is actually used
This is a technical adverb, most common in chemistry, Earth science, biology, and isotope-ratio studies. It is normally used with a term describing an isotopic treatment or property, especially “labeled,” “enriched,” “distinct,” or “traced.”
