The sensors are made of a stack of suspended electrodes that allow the solution to occupy the space between them and create a larger interface area between the aqueous solution and the electrodes. Increasing the solution-electrode interface area drastically changes the impedance of the sensor-solution resulting in a better sensitivity. Low concentrations of di-ethylhexyl phthalate (DEHP) in deionized water are used as the target chemical to demonstrate the advantage of new design over conventional planar interdigitated sensors. Experimental measurements are carried out to characterize the response of the planar and 3D sensors and their Nyquist plots are compared, displaying significant sensitivity improvement in 3D sensors. An electrical model for the sensors is developed that considers different physical phenomena such as doublelayer capacitance, solution resistance, Warburg effect and parasitic parameters. Nonlinear interpolations of the experimental data show that the equivalent electrical circuit is in good agreement with the Nyquist plots obtained from test data. The curve fitting of the tested data to the equivalent electrical circuit displays good agreement between the model and the tested data.","PeriodicalId":13753,"journal":{"name":"International Journal of Analytical and Bioanalytical Methods","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74426756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Percentages of recoveries were in the range 86% - 100% with percentage relative standard deviation (% RSD) ≤ 6% for all amino acids. Limit of detection (LOD) and limit of quantification (LOQ) values were within 0.024-0.069 g/100 g and 0.025-0.078 g/100 g respectively. A wide working range with satisfactory linearity having regression coefficients ≥ 0.999 were reported for all the amino acids. Complying with international guideline requirements, this validated method can be successfully applied for the determination of seventeen TAAs including all essential amino acids in rice.","PeriodicalId":13753,"journal":{"name":"International Journal of Analytical and Bioanalytical Methods","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77345686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective of the study is to determine whether MSG is included in dry and wet products that sold in the market and long-term study, how it affects the people once the MSG was detected in the samples and consumed by them. In this current study only detection of MSG was carried out and reported. The samples and the MSG standards are purchased from several grocery markets in Oman and taken picture of the different dry products and wet products. Samples were analysed using Statistics, Thin Layer Chromatography (TLC) and Liquid ChromatographyMass Spectrometry (LCMS). ANOVA statistical analysis was employed for this study. Statistical analysis was performed by SPSS software (Version16). The samples were weighed (equivalent to 1.0 gram) and diluted to 100 ml with HPLC water. TLC for all the samples were done using the mobile phase Methanol:Chloroform:Formic acid (5:5:1). 10 Microlitre used for spotting the samples and standard in the TLC plate. Samples showing high Rf value in TLC were confirmed by LC/MS. Most of the products showed the presence of MSG in the TLC. This study highlighted the importance of adequate baseline and control data and indicated that such a rigorous protocol for individual assessment is feasible.","PeriodicalId":13753,"journal":{"name":"International Journal of Analytical and Bioanalytical Methods","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77162797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
