“…Fuels are complex matrices obtained through different refining processes, in addition to receiving the addition of other chemical compounds [2]. To ensure the quality of fuels, distributors use markers to control the origin and quality of their products and to combat potential fraud and adulteration [3]. These markers can be dyes, specifically known as marker dyes.…”

The detection and quantification of color in fuels is a practical method for the initial screening of quality and safety in these products. In this regard, researchers have been exploring alternatives for more effective and accurate color detection and quantification systems. This study aims to develop and evaluate a simple and cost-effective photometric methodology for quantifying color in colored fuels using a free software. The proposed technique is based on photographing the sample under standard conditions, with a calibration curve for each dye being measured by color intensity. Additionally, this work compares the proposed methodology with UV-visible spectroscopy to assess its effectiveness compared to other techniques. Preliminary results indicate that the proposed methodology is a viable alternative for the detection and quantification of dyes in fuels, showing good precision and reproducibility. Moreover, the technique can be employed in monitoring the quality of fuels available at gas stations, distributors and ethanol plants. This research makes an important contribution to the field of fuels by introducing a new technique for the detection and quantification of dyes in fuels. RESUMOA detecção e quantificação da cor em combustíveis é uma forma prática para triagem inicial de qualidade e segurança desses produtos. Nesse sentido, pesquisadores têm buscado alternativas de sistemas de detecção e quantificação de cores mais eficazes e precisos. Este estudo visou desenvolver e avaliar uma metodologia fotométrica simples e de baixo custo para quantificação de cor em combustíveis coloridos, utilizando software livre, como alternativa à simples análise visual direta. A técnica proposta baseia-se na fotografia da amostra em condições padrão, sendo a curva de calibração para cada corante medida pela intensidade da cor. Adicionalmente, este trabalho compara a metodologia proposta com espectroscopia UV-visível, a fim de avaliar sua eficácia em relação a essa técnica. Os resultados preliminares indicam que a metodologia proposta é uma alternativa viável para a detecção e quantificação de corantes em combustíveis, apresentando boa precisão e reprodutibilidade. Além disso, a técnica pode ser utilizada na fiscalização da qualidade dos combustíveis disponíveis nos postos, no recebimento de matérias primas em distribuidoras e usinas de etanol anidro. A pesquisa apresenta uma interessante contribuição para a área de combustíveis, descrevendo uma técnica quantitativa simples de detecção e quantificação de cor em combustíveis.

“…Fuel dying and marking must be carried out using a specific methodology [1,6]. However, an exact chemical analysis method which allows the determination of various fuel dyes, markers and, also, their concentration effectively in one run is not yet available [2][3][4][5][6][7][8][9][10]. The difference and variety of analytical methods suitable for the determination of fuel dyes and markers have appeared for all EU countries using different combinations of dyes and markers.…”

“…The difference and variety of analytical methods suitable for the determination of fuel dyes and markers have appeared for all EU countries using different combinations of dyes and markers. There are suggestions for electrochemical [4,5], spectrophotometric [6,7], gas chromatographic [8,9] and HPLC [10] analytical meth ods to determine chosen fuel dyes or markers. But the variety of fuel dyes and markers set up the problem if country has not adopted a method for their own dyes and markers because there is no suitable analytical method to determine all fuel dyes or markers in one run.…”

A fast, precise and accurate high performance liquid chromatography method has been developed for the determination of dyes (Solvent Red 19 and Solvent Blue 35) and a marker (Solvent Yellow 124) in diesel. Separation was carried out on a 250 × 4.60 mm Agilent Zorbax Rx-SIL column (5 µm particle size). Detection was done in a visible wavelength range. The best performance of fuel dye separation and the shortest retention times were achieved when using hexane, toluene and ethyl acetate as a mobile phase. During this research the eluent composition and the elution gradient were optimized consequently that helped to perform the analysis within 15 min. The developed method was applied for the analysis of real samples of dyed diesel fuel. Preparation of the samples for the analysis simply consisted of filtering through a 0.45 µm filter previous to direct injection of the sample into the HPLC system for analysis.
