Sample preparation procedures are essential for drug analysis in biological fluids, tissues, pharmaceutical preparations, food and environmental matrices. For this purpose different techniques have been used like protein precipitation, liquid liquid extraction (LLE) and solid phase extraction (SPE). Magnetic solid phase extraction (MSPE) has become a highly preferred method due to its advantages as a sample preparation-pretreatment technique when compared to classical methods as a novel type of SPE. Basically, this type of extraction is based on the separation of different analytes from complex matrices based on the use of magnetic nanoparticles (MNPs) as adsorbents. Magnetic solid phase extraction minimizes the use of additional steps which reduces the manipulation of conventional extractions. The main advantages depend on its simplicity, environmentally friendly process, disposable cost, reduced solvent consumption, and short duration. In this review, special attention is paid on drug analysis by using MSPE prior to various analytical methods from biological, environmental and food matrices. MSPE applications, with various types of magnetic adsorbents, and different analytical method combinations were revealed for drug analysis.

“…Applications in food analysis utilizing these described modes of DSPEs have a broad range of different matrices analyzed. There are recent publications for analysis of milk, tea infusions, fruit juices, milk, pork, chicken, shrimp, rice, and among others . The great applicability of dispersive solid phase techniques can be related to the simplicity of the apparatus needed to proceed with the sample preparation (conical tube, centrifuge, and sorbent phase).…”

The accelerated rising of the world's population increased the consumption of food, thus demanding more rigors in the control of residue and contaminants in food-based products marketed for human consumption. In view of the complexity of most food matrices, including fruits, vegetables, different types of meat, beverages, among others, a sample preparation step is important to provide more reliable results when combined with HPLC separations. An adequate sample preparation step before the chromatographic analysis is mandatory in obtaining higher precision and accuracy in order to improve the extraction of the target analytes, one of the priorities in analytical chemistry. The recent discovery of new materials such as ionic liquids, graphene-derived materials, molecularly imprinted polymers, restricted access media, magnetic nanoparticles, and carbonaceous nanomaterials, provided high sensitivity and selectivity results in an extensive variety of applications. These materials, as well as their several possible combinations, have been demonstrated to be highly appropriate for the extraction of different analytes in complex samples such as food products. The main characteristics and application of these new materials in food analysis will be presented and discussed in this paper. Another topic discussed in this review covers the main advantages and limitations of sample preparation microtechniques, as well as their off-line and on-line combination with HPLC for food analysis.

Nowadays, there is an increasing need for sensitive real-time measurements of various analytes and monitoring of industrial products and environmental processes. Herein, we describe a fluorescence spectrometer in continuous flow mode in which the sample is fed to the flow cell using a peristaltic pump. The excitation beam is introduced to the sample chamber by an optical fiber. The fluorescence emitted upon excitation is collected at the right angle using another optical fiber and then transmitted to the fluorescence spectrometer which utilizes an array detector. The array detection, as a key factor in process analytical chemistry, made the fluorescence spectrometer suited for multiwavelength detection of the fluorescence spectrum of the analytes. After optimization of the experimental parameters, the system has been successfully employed for sensitive determination of four fluoroquinolone antibiotics such as ciprofloxacin, ofloxacin, levofloxacin, and moxifloxacin. The linear dynamic ranges of four fluoroquinolones were between 0.25 and 20 μg·mL−1, and the detection limit of the method for ciprofloxacin, ofloxacin, levofloxacin, and moxifloxacin were 81, 36, 35, and 93 ng·mL−1, respectively. Finally, the proposed system is carried out for determination of fluoroquinolones in some pharmaceutical formulations.
