A C18 monolithic material with a hydrophilic character was obtained by copolymerizing stearyl methacrylate (SMA) and a hydrophilic monomer poly(ethylene glycol)methyl ethermethacrylate (PEGMEA) with porogen of 1-propanol/1,4-butanediol, and the resulting material was used for solid phase extraction (SPE) of phenols in water sample.

These include methylenedioxymethamphetamine (MDMA), methylenedioxyamphetamine (MDA), 3,4-methylenedioxyethylamphetamine (MDEA) and those drugs commonly sold as “ecstasy”, which may or may not contain MDMA or its analogues.

The resulting end product is methyl ester ethoxylate, a naturally [...]

The most notable of these include the methcathinone analogue 4-methyl-methcathinone (also known as “mephedrone”).

The packing material is a porous poly hydroxymethacrylate polymer.

For example, the BELSIL® DM 5/BELSIL® PDM 20 hairspray assists in the care of damaged hair, with the polydimethylsiloxane and phenyl-modified silicones in the product working together in synergy to give hair a natural and healthy appearance.

It is therefore important for the industry to continue closely monitor the manufacturing process, identify potentially problematic conditions and develop methods that would prevent or reduce the formation of EC and maintain EC contamination at the lowest level possible during processing and storage.

Increasing both the number of food items and the number of samples per individual food commodity for laboratory analysis could provide a more comprehensive coverage and a more precise estimate of the range and average EC concentration of fermented foods in the Hong Kong market.

[...] [...] desmethylsterols” in rice bran oil should be deleted from Table 3 and reconsidered by the Committee on Fats and Oils (CCFO) for the following reasons: it was not a significant identity characteristic for the authenticity of rice bran oil, which was adequately determined by the specificdesmethylsterols mentioned in the Table; the methods of analysis were complex and the reference materials were not easily available, which created difficulties especially for developing countries; and, as it appeared from a study that low levels of other desmethylsterols could be found inrice branoil, the [...][...]
