X-Ray Findings - How to sift through

Looking for some input on my process here.

So we product tomato products and sauerkraut products. We have an X-ray that we monitor and record the findings of. I am having a very hard time actually going thru the jars and finding what was causing the X-ray to eject the jar (mostly the tomato sauces). I am very certain there are things in them due to the picture, but I am using water and a double screen method (one larger and one finer) and then doing that over a catch tray. I can find things most of the time in the sauerkraut but these tomato products are tough. Any ideas for a better method. We want to track and trend what we find. 

Thanks in advance. 

Can you split the contents into two jars then run each through again?  Then keep splitting until you find what it was?
