Trace metal analysis of anaerobic adhesives is best carried out using destructive techniques because of the high concentration of fillers and thickening agents added. These additives tend to interfere with trace metals from background noise, peak blooming, and the extent of dilution may exceed the detection limits and particle sizes may be too large to nebulise an anaerobic solution into the sample introduction orifice of the ICP-OES.

The molecules produced by living organisms, natural products, are employed in our lives as flavors, fragrances, pharmaceuticals, nontraditional medicines, dyes, and pesticides, among other uses. The products of chemistry are employed in our food as preservatives, artificial sweeteners, thickeners, dyes, taste enhancers, flavors, and textnring agents. Chemistry creates such key materials as plastics, ceramics, fabrics, alloys, semiconductors, liquid crystals, optical media, and biomaterials. Chemistry also does many kinds of analysis and these include measurements of air quahty, water quality, food safety, and the search for substances that compromise the enviromnent or workplace safety. 

Carboxymethyl cellulose (CMC) is the most important cellulose ether commercially. Its DS is 0.4-1.4. DS more than 0.6-0.8 gives a good water solubility. Carboxymethyl cellulose is one of the important modified celluloses that is widely used as an additive in industries. It possesses advantageous properties, especially solubility in water, immiscibility in oil and organic solvency, which makes it act as a multifunction agent. Therefore, it functions as stabilizer, thickener, binder and suspension agent in industries such as food and pharmaceutical. Hence, analysis of the CMC production process has been studied by researchers in order to enhance the efficiency of the process to achieve specific properties of CMC needed. There are many published works about CMC. For example, optimization of carboxymethyl cellulose production from etherification cellulose has been studied by Muei in 2010 [33].
