Hi,

In my new HACCP, a signif. hazard is glass, all preventive measures are taken, but when is glass in glass, for example, deformation of container glass post packing is very difficukt to detect.

I heard about differents machine for this detection, laser, x ray, gamma ray, etc....

Dou you know about some company with this SOLUTION??

thank again,

tasi.

Thanks Enya, raising this topic again reminded me of a recent news article on our website: X-ray detection of glass contaminants in glass containers

By the way welcome to the forums Enya.

From personal experience using X-rays, it very much depends upon the homogeneity of your product. If it's a very uniform product, it's going to be easier but if it's a liquid, it might miss it because any glass sunk to the bottom may be read as the packaging.

Of course once you start saying that there is a method to remove a contaminant, you need to check it works like a metal detector. I don't know if you can get 'glass test cards' but remember you need to be checking using the same type of glass you are looking for, otherwise it might not be a valid test.

X-ray manufacturers are very fond of claiming it can prevent any contamination, bone, plastic, etc but the fact is, once you push them, their claims aren't as strong as they make out. Cooked bones detect badly in a metal detector unless they're very large, also most manufacturers don't point out you need a test card (not hard plastic) for testing for metal with an x-ray due to the risk that the hard plastic of a normal test piece might be detected as well! Personally I don't think x-rays are ever a simple solution especially if you use them instead of a metal detector. There are big claims about their sensitivity but did you know metal detectable plasters will not be detected in all orientations in an x-ray?
