Comparison of gas chromatography–mass spectrometry and liquid chromatography–mass spectrometry for the determination of fatty and resin acids in paper mill process waters

Refractory organic pollutants and toxicity in pulp and paper mill wastewaters

“…Both GC-MS and LC-MS methods show good linearity and precision in the analysis of resin and fatty acids (Latorre et al 2003). Additionally, similar results of concentration levels can be obtained with both methods.…”

“…Traditionally, resin acids have been analyzed by GC coupled with FID (Latorre et al 2003;2005). However, the analysis of complex matrices is difficult and MS detector is often more useful.…”

“…), requirement of derivatization and low stability of derivatives. However, detection limits of ng/L of some resin acids have been achieved with MS detection (Latorre et al 2003).…”

“…Effluents from pulp and paper industry contain complex matrices and a high number of diverse compounds (Latorre et al 2003). Pulp and paper mill effluents can contain over 250 identified chemicals, including harmful components, such as resin acids and sterols (Ratia et al 2012;.…”

Unconventional Raw Natural Sustainable Sources for Obtaining Pharmacological Principles Potentially Active on CNS Through Catalytic, Ecologically Clean, Processes

“…However, this method has disadvantages for us, including instability of the derivatized samples (Latorre et al, 2003), hazards of methylating reagents (potentially explosive and carcinogenic), and tedious work-up of raw biological material required.…”
