if there was a smell it would be easily detectible by humans using apparatus they have for such things as it would mean something of physical nature was traveling from these individuals into their surroundings...

I'm confused. TFA says "all dogs succeeded in each trial", and while there may have not been a lot of trials, that still sounds like grounds to believe it wasn't by coincidence.

I don't see how the fact that they didn't use a machine to smell negates their findings. Do you believe that every single time the dogs were correct was purely coincidental? Or do you believe that there's some other thing emanating from a tin containing the body odor of a person with epilepsy? I don't understand what your explanation for the results is

detecting and identifying trace molecules in air is not at all easy. there are some very specific detectors that work well, but nothing like a general electronic nose.
We use dogs in many roles due to their sense of smell. Police work, customs and border control, search and rescue etc. Using an apparatus isn’t a good substitute yet.
