Applications of matrix solid-phase dispersion in food analysis

Journal of Chromatography A, 2000
Matrix solid-phase dispersion (MSPD), a patented process for the simultaneous disruption and extraction of solid and semi-solid samples, was first reported in 1989. Since that time, MSPD has found application in numerous fields, but has proven to be particularly applicable for the analysis of drugs, pollutants, pesticides and other components in foods.

Solid-phase extraction versus matrix solid-phase dispersion: Application to white grapes

Talanta, 2007
The use of matrix solid-phase dispersion (MSPD) was tested to, separately, extract phenolic compounds and organic acids from white grapes. This method was compared with a more conventional analytical method previously developed that combines solid liquid extraction (SL) to simultaneously extract phenolic compounds and organic acids followed by a solid ...

Recent trends in matrix solid-phase dispersion

TrAC Trends in Analytical Chemistry, 2013
Abstract The key factors for the success of matrix solid-phase dispersion (MSPD) are its feasibility, flexibility, versatility, low costs and rapidity. Furthermore, with MSPD, it is possible to perform, on a small sample aliquot, extraction and clean up in a single step.

Trends and recent applications of matrix solid-phase dispersion

Analytical and Bioanalytical Chemistry, 2008
Matrix solid-phase dispersion (MSPD) is a sample-preparation technique with increasing acceptance in trace analysis of organic compounds using chromatographic and electro-driven separation techniques. It has been applied to the extraction and fractionation of a large number of substances from solid, semi-solid, and liquid matrices.

Recent advances and developments in matrix solid-phase dispersion

TrAC Trends in Analytical Chemistry, 2015
Abstract Matrix solid-phase dispersion (MSPD) is a sample-preparation process first introduced in 1989 for the extraction of drug residues from animal tissue. The feasibility and the versatility of MSPD mean it is still widely employed and applicable to a large variety of analytes and samples.

Disruption and fractionation of biological materials by matrix solid-phase dispersion

Journal of Chromatography A, 1993
The isolation of drug residues, environmental contaminants or naturally occurring component molecules from biological materials is often a complex undertaking. We report here the development and application of a simple approach to the disruption of biological samples that also allows for the rapid fractionation and isolation of the sample's natural ...

Matrix solid-phase dispersion extraction of organophosphorous pesticides from beeswax

International Journal of Environmental Analytical Chemistry, 2017
ABSTRACTBeeswax is a complex mixture of lipophilic compounds and other components such as aliphatic alcohols and carotenoids. Then, extraction and clean-up for pesticide analysis in beeswax is a challenge. In this work, a multiresidue method for the analysis of dichlorvos (DCV), diazinon, malathion, methyl parathion and coumaphos (CMF) in beeswax was ...

Multiscreening determination of organic pollutants in molluscs using matrix solid phase dispersion

Journal of Chromatography A, 2015
This work describes the optimisation, validation and application of matrix solid-phase dispersion (MSPD) coupled to gas chromatography mass spectrometry, both single quadrupole (GC-MS) and tandem (GC-MS/MS), for the quantification in molluscs of up to 40 different analytes belonging to several families of priority and emerging organic contaminants ...

Automated extraction of acetylgestagens from kidney fat by matrix solid phase dispersion

The Analyst, 1994
A new extraction method for the acetylgestagens medroxyprogesterone acetate (MPA), chloromadinone acetate and megestrol acetate, from kidney fat, has been developed. The method is a combination of matrix solid phase dispersion and solid phase extraction and is simpler and safer than previous methods, especially as it can be automated.
