RF-Tracer on Small Filter Paper (1)   RF-Tracer on Small Filter Paper


Microtracers-RF are iron powder colored with water soluble FD&C colors, designed to be used in feeds or premixes.  Microtracers-RF may be assayed qualitatively using a Rotary Detector or the Mason Jar Technique in about two minutes.  For qualitative tests, the tracer will yield a ring of color on a filter paper, indicating the presence or absence of the product it was coding.  Microtracers-RF can also be determined quantitatively by eluting the dye from the tracer, reading its absorbance at a specific wavelength, and comparing it to a set of standard curves.
