Summary

Media data and Non-free use rationale
Description	Part of an illustration of an Andersen six stage sampler, showing air flow and stages
Author or copyright owner	Ariel A. Andersen
Source (WP:NFCC#4)	https://www.ncbi.nlm.nih.gov/pmc/articles/PMC290224/
Use in article (WP:NFCC#7)	Andersen sampler
Purpose of use in article (WP:NFCC#8)	For visual identification of the object of the article. The article as a whole is dedicated specifically to a discussion of this work.
Not replaceable with free media because (WP:NFCC#1)	Any derivative work based upon the artwork would be a copyright violation, so creation of a free image is not possible.
Minimal use (WP:NFCC#3)	Only part of the figure (the top two stages) is used to illustrate the air flow of the six-stage Andersen sampler. The rest of the figure is cropped out.
Respect for commercial opportunities (WP:NFCC#2)	The use of a low resolution image of the artwork will not impact the commercial viability of the art.
Other information	As a pre-1989 work, if copyright notices haven't been explicitly added, and nothing is filed with the copyright office after the fact by the journal or the author, more conditions could be allowed, but I haven't checked.
