Colate specific strings and list to a new sheet ?

I’m puzzling over this.  I have “Sheet1” with cells say A1 to E33 with test results in the form of strings. These cell strings include “Pass”, “Fail”, etc but also a few with a reference like “artfxxxxx”, where xxxxx is a varying five digit number.  I want to find in “Sheet1” the unique “artfxxxxx” strings only and list them in a column in say “Sheet2” ? 

Here is an example of what I'm trying yo achieve...

Sounds like it should be easy, thanks.
