Progress of sample preparation and analytical methods of dried fruit foods

Chinese Journal of Chromatography, 2021
Dried fruit foods, including nuts and preserved fruits, are favored by consumers and are rich in protein, lipids, minerals, vitamins, and other nutrients. However, these food products can be contaminated by pesticide residues, heavy metals, mycotoxins, and additives during growth, processing, storage, and transportation. The presence of such pollutants

Solid phase analytical derivatization as a sample preparation method

Journal of Chromatography A, 2013
Analytical derivatization (AD) is an important procedure in analysis as it improves the sensitivity, selectivity and chromatographic separation. Solid phase analytical derivatization (SPAD) combines extraction and derivatization into a single step fulfilling many aspects of a good sample preparation technique, which includes low organic solvent ...

A sample preparation method for recovering suppressed analyte ions in MALDI TOF MS

Journal of Mass Spectrometry, 2015
In matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI TOF MS), analyte signals can be substantially suppressed by other compounds in the sample. In this technical note, we describe a modified thin‐layer sample preparation method that significantly reduces the analyte suppression effect (ASE). In our method, analytes are

Synthetic Cannabinoids in Biological Specimens: A Review of Current Analytical Methods and Sample Preparation Techniques

Bioanalysis, 2018
Synthetic cannabinoids are a new class of chemical drugs capable of modifying human behavior. These products do not contain cannabis, but produce similar effects after consumption. The fact that they are easily accessed, and are many times considered to be harmless, justifies their widespread use among young people.
