Imperative sentence

English Medical Chemistry; Chem Sci/Eng
Context: Test Sample Preparation Method:
Dissolve 5 g xxxx (batch. No: 02030) in 10 ml ethyl acetate at 40¡æ, and add 2 g chromatographic silica gel for adsorption. Condense the mixture under vacuum to a dry matter, which was taken as the stock sample. Add about 22 g chromatographic silica gel into a 60 ml sand core funnel that was then shaken for compactness, and add the stock sample. Cover with a filter paper and let the sample dissolve and evenly flow down. Rinse 10 times with 20 ml of ethyl acetate under reduced pressure and monitor the thin-layer chromatographic process. Combine fractions 2-5, let the combined fraction condense to 15ml and precipitate via naturally cooling down. Cool in a refrigeratory, filter and dry, thus 3 g resulting product obtained for use.

Question: it is in a research report not a use instruction.

Can imperative sentences be used in this kind of "Method"?

TIA!!!

Discussion

Ah - of course. . .well then, I'm with Enza. :)
Non-ProZ.com Aug 31, 2005:
It might not seem strange. In research papers there usually is " mehod and materials", which discribes how to do the test.
I'm a little confused here. "Test sample preparaton method" indicates a instruction for WHAT to do (imperative). But at the end you say it is a report, not a use instruction, which makes me think it is a description of an event in the past (past tense)?

yes

One of the uses of the imperative is to give instructions -in your case, giving instructions on how to prepare the test sample.
Peer comment(s):

agree Alex Crichton : If you were to aviod the imperative in aprodedure this long (e.g. with passives), it would get tiresome.

agree RHELLER : a method implies instructions and we always use imperatives for instructions (like a recipe)

I'm not so sure. Since you say it is a research report - not a use instruction, that sounds to me like you are describing something that has already happened. (and it seems to show up in the sentence beginning "Condense . .. which WAS taken." However, your context says "test sample preparation method, which WOULD indicate you can use imperative, as Enza Longo suggests. I realize now I should have asked a question for clarification! I'll do that!
