A method for measuring bonding agent content and distribution in a composite product that includes bonding agent and cellulosic material. The method involves using a bonding agent that includes electronegative functional groups and an X-ray active cationic label bonded with the functional groups in the manufacture of the composite product. The cellulosic material is exposed to X-rays to generate a characteristic fluorescence signal from the label. The X-ray fluorescence of the label is measured to determine the amount and distribution of the label in the cellulosic material and thereby the amount and distribution of the bonding agent in the composite product. The present invention also provides a bonding agent composition useful for determining the distribution of the bonding agent in a composite product comprising a bonding agent containing electronegative functional groups and a label compound that includes positively charged ions to emit characteristic fluorescence when exposed to X-rays. The bonding agent and the label compound are homogeneously mixed.
