Mild source conditions (temperature: 90°C, capillary voltage: 2.5kV, sampling cone: 30V, desolvation gas flow: 800L/h, desolvation temperature: 250°C) were used in order to minimize back-exchange while ensuring proper desolvation (73). Peptide identification was assisted by collision induced dissociation collected in the MSE mode, using PLGS 3.0.2 and UNIFI 1.8. Deuterium incorporation was determined in DynamX 3.0. Structural figures were prepared using PyMOL 1.8.2.3

troca reversa (back-exchange)
Acho interessante apresentar uma proposta de tradução, mantendo ao lado, entre parênteses o termo original.
Ex.:

...amostras foram mantidas em gelo para evitar troca reversa

Encontrei referências que utilizam o termo original, segue exemplo:
file:///C:/Users/dell/Downloads/2017_SamuelCoelhoMandacaru.pdf
"A troca também pode acontecer nos sítios O-H, N-H e S-H das cadeias laterais; no entanto, esses deutérios são perdidos durante a cromatografia líquida (LC), em um processo chamado back-exchange."
"Existe, no entanto, um problema no qual as amidas deuteradas podem sofrer back-exchange durante o processo de separação [134, 135]. Para minimizar este back-exchange, o sistema é refrigerado a 15 °C durante a digestão e a 0 °C durante a separação cromatográfica."

Neste caso específico, encontrei bastantes sugestões coincidentes com a sua proposta, bastantes para validá-la. :)
