“…The performance of PRiME pass through SPE in extracting MG and LMG was compared with that of previous publications in terms of CCα and CCβ . Dowling reported the CCα 0.17 μg/kg and CCβ 0.30 μg/kg for MG and CCα 0.15 μg/kg and CCβ 0.35 μg/kg for LMG in salmon samples using a traditional SPE LC‐MS/MS method .…”

Kaplan achieved the CCα 0.43 μg/kg and CCβ 0.56 μg/kg for MG and CCα 0.24 μg/kg and CCβ 0.31 μg/kg for LMG in rainbow trout samples, who used deuterium‐labelled internal standards thus solvent extracted the target analytes directly without any clean‐up step prior to LC‐MS/MS . As the values of CCα and CCβ of the proposed PRiME UPLC‐MS/MS demonstrated in Section 3.2.3, the sensitivities of these three methods borne a fairly close resemblance because they showed the same order of magnitudes of CCα and CCβ.…”

“…Suitable sample pretreatment techniques are necessary for accurate detection of MG because direct analysis of MG in real samples through LC‐MS/MS is complicated due to the complexity of sample matrix and generally low level of analytes . The commonly used sample purification methodologies, such as liquid‐liquid extraction , SPE and redissolution , are ineffective, time‐consuming, cumbersome to operate, and consume large volumes of organic solvents and labor. Modern trends in analytical chemistry are towards the simplification, eco‐friendly, and in increasing of selectivity and sensitivity .…”

A high‐throughput PRiME (process, robustness, improvements, matrix effects, ease of use) sample purification procedure was developed to simplify the multiple steps of traditional SPE in extracting the malachite green and leucomalachite green in Chinese softshell turtle (Pelodiscus sinensis). The sample loading volume, extracting solvent type, and pH value of the employed PRiME hydrophilic‐lipophilic balance cartridge for sample purification were optimized to be 3 mL, acetonitrile, and pH 5, respectively. In comparison with traditional SPE, the PRiME process is cost‐effective, solvent‐saving, and simple to operate, which only consists of a passing through step without traditional sorbent conditioning and impurity washing. Afterward, eluate was analyzed by ultra‐performance liquid chromatography‐tandem mass spectrometry, and the proposed method was validated for linearity (R2 > 0.9992), intraday precision (2.44–3.22%), interday precision (3.28–6.58%), sensitivity (LOD ≤ 0.18 μg/kg and, LOQ ≤ 0.60 μg/kg), and recovery (88.7–94.1%, RSD < 6.79%). The results indicated that the PRiME technique can simplify the sample preparation procedure by avoiding the tedious steps, such as conditioning, washing, etc. It would be of significant interest for environmental and food safety applications in the market of Chinese softshell turtle and related products.

“…Matrix effect (ME) can generally be defined as one or more components from the matrix acting on the analyte concentration measurement, and it may appear an increase or decrease in the detector signal (signal enhancement or suppression). The resulting values less than 100% indicate ion suppression whereas the values greater than 100% defines to ion enrichment 28 . ME may be categorized in accordance with the literature as follows: (a) ±0–20% no effect or light effect; (b) ±20–50% medium effect, and (c) above ±50% strong effect.…”

Nowadays, a wide variety of chemicals has emerged because of increasing industrial and human activities. Thus, environmental chemistry laboratories performing analytical measurements need rapid and sensitive methods more than ever to get reliable quantitative data. For this purpose, a purge and trap gas chromatography–mass spectrometry (GC‐MS) method was developed and validated for the rapid, simple, and sensitive determination of the presence of naphthalene and its derivatives in waters. The method validation was based on specificity, calibration curve linearity, limit of detection (LOD) and limit of quantification (LOQ), accuracy (recovery), precision, matrix effects (MEs), and measurement uncertainty. This method showed excellent linearity from 1.00 to 40.00 μg/L except naphthalene (0.50–40.00 μg/L) because the correlation coefficients were higher than 0.997 for all analytes. The LOQ values varied from 0.312 to 0.746 μg/L, and the LOD values changed from 0.094 to 0.224 μg/L with relative standard deviations (RSDs) for all compounds below 10% (3.12–7.46), respectively. Recoveries ranged from 81.9% to 95.6%, and repeatability and reproducibility (in terms of RSD for six measurements) were lower than 10% in all cases. F test was subjected on the related data at 95% confidence level, and no statistically significant difference was observed. There was no critical ME (recovery varied from 80% to 110% in all matrices). In measurement uncertainty, the expanded uncertainties of each analyte were changed in the range of 0.39–0.52 μg/L, and the calibration curve and repeatability had dominant effects on the combined uncertainty. The application to real samples was successfully assessed by the developed method. These results indicate that the developed method is suitable for the determination of naphthalene and its derivatives in waters.

A simple supramolecular dispersive liquid-liquid microextraction-solidified floating organic drop (SMDLLME-SFOD) method was developed for the separation and preconcentration of brilliant green (BG) before its spectrophotometric determination. The method is based on the extraction of ion-pair of BG with sodium dodecyl sulfate into the coacervates made up of decanoic acid reverse micelles in the tetrahydrofuran-water mixture. The influence of the effective parameters on the extraction of BG was investigated and optimized using response surface methodology. Under the optimized conditions, the calibration graph was linear in the range of 1.0-50.0 μg L À1 of BG. The limit of detection (LOD) and limit of quantification (LOQ) were 0.28 μg L À1 and 0.94 μg L À1 , respectively. The repeatability expressed as the relative standard deviation for six replicate measurements at 5.0 μg L À1 BG was 3.6%. The method was successfully applied to the extraction and determination of BG in different water and fish samples.
