FAQs
How is "as input material" typically used in scientific writing?
In scientific writing, "as input material" specifies the substance used at the beginning of a process, often with precise details about its quantity and preparation. For example, "A total amount of 3 μg RNA per sample was used "as input material" for the RNA sample preparation."
What are some alternatives to "as input material"?
Alternatives include "as raw material", "as feedstock" (especially in industrial contexts), or "as a component", depending on the specific context and nuance you want to convey.
Is it more appropriate to say "as input material" or "as the input material"?
