Determination of the main aliphatic carboxylic acids in kraft black liquors by high- performance liquid chromatography-mass spectrometry
In kraft pulping, wood polysaccharides are subjected to the end-wise degradation (i.e., the peeling reaction) under alkaline conditions with the simultaneous formation of a large number of water/alkali-soluble hydroxy monoand dicarboxylic acids together with formic and acetic acids [1-3]. The versatile analysis of organic material in black liquor is of a great importance, for example, for monit...
متن کاملSimultaneous Determination of 13 Priority Polycyclic Aromatic Hydrocarbons in Tehran’s Tap Water and Water for Injection Samples Using Dispersive Liquid-Liquid Micro Extraction Method and Gas Chromatography-Mass Spectrometry
Abstract Polycyclic aromatic hydrocarbons (PAHs) are classified as persistent and carcinogenic organic pollutants. PAHs contamination has been reported in water. Many of relevant regulatory bodies such as EU and EPA have regulated the limit levels for PAHs in drinking water. In this study, 13 priority polycyclic aromatic hydrocarbons (PAHs) were determined in tap water samples of Tehran and wat...

متن کاملImproved characterization of tomato polyphenols using liquid chromatography/electrospray ionization linear ion trap quadrupole Orbitrap mass spectrometry and liquid chromatography/electrospray ionization tandem mass spectrometry.
Tomato (Lycopersicon esculentum Mill.) is the second most important fruit crop worldwide. Tomatoes are a key component in the Mediterranean diet, which is strongly associated with a reduced risk of chronic degenerative diseases. In this work, we use a combination of mass spectrometry (MS) techniques with negative ion detection, liquid chromatography/electrospray ionization linear ion trap quadr...
متن کاملDetermination of ethyl glucuronide in hair samples by liquid chromatography/electrospray tandem mass spectrometry.
A method for the determination of ethyl glucuronide (EtG) in hair samples, using liquid chromatography/electrospray tandem mass spectrometry (LC/ESI-MS/MS), was developed and validated. The treatment of hair samples was as follows: to 100 mg of washed (dichloromethane followed by methanol, 1 ml each) and cut (1-2 mm) material, 700 microl of water, 20 microl of internal standard solution (pentad...
