Solid-Phase Extraction (SPE): Principles and Applications in Food Samples.
Solid-Phase Extraction (SPE) is a sample preparation method that is practised on numerous application fields due to its many advantages compared to other traditional methods. SPE was invented as an alternative to liquid/liquid extraction and eliminated multiple disadvantages, such as usage of large amount of solvent, extended operation time/procedure steps, potential sources of error, and high ...
متن کاملRemoval of Triton X-100 from Plasma Samples Using Mixed-Mode Solid Phase Extraction (SPE)
in t ro du C t io n Pharmaceutical dosing vehicle excipients such as Triton X-100 are often added to formulations to facilitate dissolution in dosing media. Unfortunately, these compounds can cause significant matrix effects, typically ion suppression, in LC/MS/MS analyses. The use of fast LC gradients, common in drug discovery, can result in co-elution of target analytes with these compounds. ...
متن کاملIntroduction to Solid-phase Extraction
We have a sample in front of us. It is of unknown composition, but we know that it is complex, containing anywhere from a few hundred to many thousand chemical components. It is of uncertain physical form perhaps it looks like a liquid, but it has solid particles floating in it. We think that a particular compound is present in that sample, somewhere and in some form, but we don't know how much...

متن کاملAutomated Solid Phase Extraction (SPE)-LC-MS/MS Method for the Determination of Acrylamide in Brewed Coffee Samples
Acrylamide is thought to be produced during the roasting process associated with coffee production. Acrylamide has been labeled as a probable human carcinogen. Due to the use of roasted coffee beans in making coffee and the high consumption of coffee world-wide, brewed coffee could be a source of daily exposure to acrylamide. Acrylamide determination has been shown to be challenging due to pres...
