Three factors were evaluated: (i) adsorbent nature (neutral alumina, silica gel and C₁₈); (ii) eluent strength (dimethylformamide, methanol and acetonitrile); and (iii) sample-adsorbent ratio (1:1; 1:5; and 1:10, m/m). Successful extraction of dyes was achieved using dimethylformamide as eluent, neutral alumina as adsorbent and sample:adsorbent ratio of 1:5 (m/m). Adsorption and kinetic studies suggest strong interaction between dye and adsorbent. Furthermore, employing digital image colorimetric detection, the study observed limit of detection (LOD) ranging between 3.8 to 29.8 µg <em>L</em> ⁻ ¹ and limit of quantification (LOQ) ranging between 12.3 to 90.3 µg <em>L</em> ⁻ ¹ with R² &gt; 0.9927 for both dyes, CV and CR, respectively. Notably, recovery was greater than 86 % with a relative standard deviation (RSD) inferior to 7 % (<em>n</em> = 3). These findings indicate the effectiveness of the improved multivariate optimization technique in conjunction with matrix solid-phase dispersion for successful extraction and quantification of dyes from shrimp samples, showing its potential for accurate and sensitive detection in similar analyses. The proposed method was compared with the gold method (UV/Vis spectroscopy) and the statistical treatment showed that the results of both methods are comparable.</p></div>","PeriodicalId":100052,"journal":{"name":"Advances in Sample Preparation","volume":"9 ","pages":"Article 100105"},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772582024000044/pdfft?md5=4e59eb26368687cab5089e61463b286f&pid=1-s2.0-S2772582024000044-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139743487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Resveratrol, flavonoids (quercetin and kaempferol), and phenolic acids (caffeic, p-coumaric, and trans-ferulic acids) were used as model compounds based on their concentrations reported in craft beers. SALLE with acetonitrile was effective for sample cleanup, with recoveries ranging from 84% to 112%. The on-column concentration was carried out in high performance liquid chromatography by starting the gradient elution with acidified water (sample carrier stream) in a reversed-phase mode. Consequently, the analytes were retained in a narrow band, and highly polar/ionic potentially interfering species were flushed from the column. The effectiveness of the approach was demonstrated by linear correlations between the peak areas and the injected volumes from 10 to 200 µL (r ≥ 0.999), without significant variations in peak width (&lt; 10%) or retention times (&lt; 0.7%), and peak symmetry (tailing factors within the range of 0.8–1.1).
