Hello

Is there a test determine the amount of lubricant on the wire surface that can be made in the production line?
We usually do a test by taking a sample of the wire to the lab. Clean it and do a weight difference analysis but it takes too much time.

Thanks

You may wash the wire boiling ch2cl2, liquifying it with a heat exchanger and washing with it the wire (continous cycle). Then evaporate ch2cl2 and measure remaining lubricant that you collect in a bottle. 1kg of wire is enough. Your scale should be able to measure mgrs.
