“…Various certified reference materials databases, such as the COMAR database, the EVISA database, and the Web sites of specific producers, were utilized to screen for seleniumcontaining monosaccharides. 17 Selenium-containing monosaccharide standards have not been synthesized, mainly due to their high instability and structural complexity, which lead to difficulties in the preparation of reference materials, purity and impurity evaluation, and quantitative traceability technology.…”

“…The PT results implied that the laboratory performance was insufficiently satisfactory for AFB 1 measurements in food matrices. It has been recommended to food testing laboratories by the accreditation body that traceable certified reference materials (CRMs) could be used in the quality control . Well-characterized CRMs are often essential to evaluate the performance of existing methods and to develop new analytical methods. − Moreover, CRMs are the basic pillars to achieve metrological traceability in the frameworks of international agreed standards .…”

Aflatoxin B 1 in a peanut oil matrix certified reference material (CRM, GBW10176) has been issued for accurate determination of aflatoxin B 1 in real samples. This matrix CRM was prepared from commercial peanut oils naturally contaminated by aflatoxin B 1 , with the aid of a liquid−liquid extraction process. Specially, the certified value of CRM was determined using two individual approaches, liquid chromatography−isotope dilution tandem mass spectrometry and standard addition liquid chromatography−fluorescence detection techniques. More importantly, assessments of homogeneity and short-and long-term stabilities confirmed that the GBW10176 CRM was sufficiently homogeneous between packages or within package, and it could be stable up to 7 days stored below 50 °C or 18 months at 4 °C. The metrological traceability of GBW10176 was ensured by the application of pure aflatoxin B 1 (GBW10172). Its uncertainty was evaluated with the contributions from the characterization, homogeneity, and stability. Resultantly, the certified value of the aflatoxin B 1 CRM (GBW10176) was 23.4 μg/kg with an uncertainty of 3.1 μg/kg (k = 2).

Medicated bath is the most common spiking method used in the development of matrix reference materials for aquatic products; however, the environmental issues caused by the treatment of waste liquid after medicated bath cannot be ignored. We proposed an environmentally friendly spiking method based on microfluidics, which significantly improved the drug utilization rate without the need for subsequent drug residue treatment. Finely processed minced fish samples were fully mixed with quinolone drugs, and minced fish gel microspheres were prepared by microfluidic technology, utilizing the gel's water-locking function to enhance the drug-loading capacity. The results showed that this method can significantly increase the drug-loading capacity of the matrix (2.33−4.03 times) compared with the traditional spiking methods. In addition, the matrix reference material prepared by this method has good stability, and the drug concentration was adjustable and controllable.
