“…The first step of MSPD is to homogenize the targets and the dispersant with mortar and pestle. The grinding process needs manual operation, and the related parameters depend on the operator such as strength, speed and time [17]. The introduction of ball mill instrument realizes the first step automation of MSPD, because the strength, vibration frequency, and vibration time of ball mill are controllable.…”

Rubi Fructus, a common traditional Chinese medicine, is abundant in phenolic components with pharmacodynamical effect. An efficient and rapid ball mill‐assisted vortex‐enhanced matrix solid‐phase dispersion method was developed for the simultaneous quantification of five phenols (ellagic acid, kaempferol‐3‐O‐rutinoside, astragalin, tiliroside, and kaempferol) in Rubi Fructus by high‐performance liquid chromatography. The introduction of the ball mill instrument realized the automation of the first step of matrix solid‐phase dispersion. Several extraction parameters were evaluated, and the best extraction conditions were optimized by response surface methodology. The method exhibited a good linearity for the five compounds (r2 > 0.999). The recoveries of the five target analytes in Rubi Fructus ranged from 98.7% to 102% (RSD≤3.92%) under the optimized conditions: Al‐SBA‐15 as a dispersant, sample/dispersant ratio of 1:3, ball milling time as 2 min, vibration frequency of the ball mill as 1300 rpm, 1.4 mL methanol as eluent and vortex time as 3 min. Consequently, the established ball mill‐assisted vortex‐enhanced matrix solid‐phase dispersion combined with HPLC could be applied to extract and analyze the target phenolic compounds in Rubi Fructus samples.

“…As is well known, sample pretreatment is a key procedure for the analysis of pesticides residue [4]. In recent years, varieties of pretreatment methods, such as solid-phase extraction (SPE), solid-phase microextraction and matrix dispersion SPE, have been developed for the enrichment of pyrethroids in aqueous solutions [5,6,7]. Among them, magnetic SPE (MSPE) is a new type of SPE technique which is based on the magnetic adsorbent, and has gained huge attention in bioseparation and chemical analysis [8].…”

A simple, sensitive and effective magnetic solid-phase extraction (MSPE) technique was developed for the extraction of pyrethroid pesticides from environmental water samples, followed by gas chromatography tandem triple quadrupole mass spectrometry determination. An adsorbent of magnetic zeolitic imidazolate framework-8@deep eutectic solvent (M-ZIF-8@DES) was prepared using deep eutectic solvent coated on the surface of M-ZIF-8. The features of M-ZIF-8@DES were confirmed by material characterizations, and the results indicated that M-ZIF-8@DES has a good magnetism (61.3 emu g−1), a decent surface area (96.83 m2 g−1) and pore volume (0.292 mL g−1). Single factor experiments were carried out to investigate the effect of different conditions on the performance of MSPE. Under the optimal conditions, the developed method performs good linearity (R2 ≥ 0.9916) in the concentration range of 1–500 μg L−1. The limits of detection were in the range of 0.05–0.21 μg L−1 (signal/noise = 3/1). The intraday relative standard deviation (RSD) and interday RSD were less than 9.40%. Finally, the proposed technique was applied for the determination of pyrethroid pesticides in environmental water samples. This work shows the potential of DES-modified metal-organic frameworks for different sample pretreatment techniques.

“…Today, it is generally accepted that, with such instruments, the initial amount of sample can be reduced without affecting the precision and accuracy of the finally reported results. Thereby, advances achieved the in instrumental field during the last decades have promoted a significant development in the sample preparation area, where new miniaturised and sometimes simplified treatment procedures have been proposed [2][3][4].…”

Matrix solid-phase dispersion (MSPD) is a nowadays widely accepted technique for the one-step extraction and purification of organic analytes in different research areas. The several innovations incorporated since its introduction 30 years ago have progressively contributed to increase its simplicity, flexibility, rapidity, robustness and straightforward nature. In recent years, progress in MSPD has continued through the incorporation of new engineered and tailored sorbents and solvents to the process, which have facilitated its miniaturization due to the enhanced sorption capacities and improved selectivity provided by these reagents. In some cases, these improved features have also stimulated the combined use of MSPD with other enhanced solvent extraction techniques, resulting in even faster, greener and less manipulative methodologies. This review paper discusses recent advances in these fields through representative application studies dealing with the analysis of organic compounds in environmental and food samples.
