Would you please let me to know about the methods for measurement of medullation and Kemp % on animal? My problem is that the wool sampling and sending to laboratory is not possible. So I would like to verify the possibility of a method to measure Kemp/medullation % in wool rapidly on the animal. I know "Benzene test" (attached file) for distinguishing of Kemp fibers, but Benzene is a risky material. Furthermore the use of portable OFDA in our situation is not possible.
Is there safe substance similar to benzene that has the similar optical refractive index ? Which safe liquid can be found that has a light refractive index similar to wool? (1.54). Sincerely,
Try an optical based system. for example, place a thin layer of fibers on a scanner or photocopier and make an image; enlarge the image and count the kemp fibers and total fibers. Divide the number of kemp fibers by the number of normal fibers to get % kemp fibers. There are several optical fiber scanning systems you could buy if you have the budget. (see, for example, www.isatag.ch) and you can send them a sample to check if it can really do what you want it to do before making any purchase.
Alvin Ulrich , Thank you for your response. Would you please check the link address www.isatag.ch . I could not access to it. Kind Regards, Seyed
