Increase the concentration of formaldehyde outside of TEA – how should this be translated here?
Out of” has many meanings: outside of…, from inside, because of, coming from, not suitable for/compatible with…, leaving, separating from… Here I guess it should mean “the formaldehyde content in TEA
First, thank you to the person who replied above; it’s an email sent by a foreigner. However, TEA itself does not contain formaldehyde.
Lack, absence, giving up, loss – these factors increase the concentration of formaldehyde in TEA. Without TEA, the concentration of formaldehyde can increase; or removing TEA can also increase its concentration. Out of office, out of danger. Without an official in charge, there is no risk. Please consider the context again.
Increase the concentration of formaldehyde outside of TEA Use TEA to increase the formaldehyde concentration
Increase the concentration of formaldehyde rather than TEA
