There are two things that clue me in - attention to detail and the ability to follow directions. I give a test that has explicit instructions and it works every time. The test has both math and non-math problems but is mostly logical. The questions are more broad so that I can see their thought process.

I also weed candidates out immediately in the job description by throwing in a sentence in the middle that instructs them to send their resume with the subject line "entropy" or some other key word. When I get emails with resumes I simply delete those that don't have the key word.

I don't see how this measures analytical capabilities.

For example, people with mild ADHD will probably fair poorly on your tests. Now, if you are hiring for something that requires profound attention to detail (dispensing medicines in a hospital), keep on. If you are trying to measure analytical abilities, you should try measuring that, not some proxy that has little to do with analytical abilities.

(and the reverse also applies - I know people with great attention to detail but that I wouldn't rate particularly highly on analytical skills).
