“…MALDI‐TOF MS can be used for routine control of sulfonated azo dyes in food products as a memory‐free, simple, low‐cost method. Negrete et al reported a simple MALDI‐TOF MS procedure that successfully determined five sulfonated azo dyes in chili powders (Negrete et al, 2019). In another study by Zeng et al (2018), water‐soluble and biocompatible small‐molecule near‐infrared II (NIR‐II) fluorescent dye H2a‐4T complexed with fetal bovine serum, and Cetuximab proteins were prepared (Zeng et al, 2018).…”

“…ESI‐Q‐TOF has an accurate ion isotopic distribution and exact mass analysis at sub‐ppm or ppm levels for organic compounds, which is useful for the identification of dyes and their degradation components. Q‐TOF is used often in conjunction with ESI (Hisaindee et al, 2013; Kuenemann et al, 2017; Y. Li et al, 2020; Liu et al, 2021; Sultana, Liu, et al, 2018) and appears to be one of the more commonly applied methods for MALDI analysis as well (Negrete et al, 2019; Zeng et al, 2018). Triple quadrupoles are commonly used for ESI, appearing frequently in research and industry due to their ease and cost (Arrizabalaga‐Larranaga et al, 2019, 2021; Hu et al, 2018; Rubio et al, 2021; Shen et al, 2017).…”

Synthetic dyes are found in a wide variety of applications today, including but not limited to textiles, foods, and medicine. The analysis of these molecules is pertinent to several fields such as forensics, environmental monitoring, and quality control, all of which require the sensitivity and selectivity of analysis provided by mass spectrometry (MS). Recently, there has been an increase in the implementation of MS evaluation of synthetic dyes by various methods, with the majority of research thus far falling under electrospray ionization and moving toward direct ionization methods. This review covers an overview of the chemistry of synthetic dyes needed for the understanding of MS sample preparation and spectral results, current fields of application, ionization methods, and fragmentation trends and works that have been reported in recent years.

The Coated-Wire Ion-Selective Electrode (CWISE) of Tartrazine Using Chitosan as an Ionophore

et al. 2021

View full text Add to dashboard Cite

Research on the Ion-Selective Electrode (ISE) of coated wire-type tartrazine using chitosan as an ionophore has been developed. The variables used in the manufacture of ISE are membrane composition and immersion time. Meanwhile, the basic characteristics of ISE measured are Nernst value, measurement concentration range, detection limit, and measurement response time. The results showed that ISE tartrazine coated wire type had an optimum membrane composition in a mixture of chitosan: PVC: DOP of 3: 34: 63 (% w/w) and a membrane immersion time 20 minutes. The basic characteristics of ISE produce a Nernst value of 20.976 mV/decade. The measurement concentration range is 1×10-7-1×10-2 M with a detection limit of 2.749×10-7 M or 0.1469 ppm. The response time ranges from 10-60 seconds, with an average of 40 seconds.

“…Nevertheless, the combined use of liquid chromatography and a diode‐array detector (LC‐DAD) and mass spectrometry (LC/MS) is the method of choice for the quality control of hydrazone dyes, especially in food matrices 8 . Different MS ionization sources have been used, such as thermospray, 22 laser desorption ionization, 23 matrix‐assisted laser desorption ionization, 24 atmospheric pressure chemical ionization, 25 and electrospray ionization (ESI) 26 . Most studies are based on the use of HPLC‐DAD 25–37 and LC/MS (using triple quadrupole or ion trap instruments as detectors), 22,25,26,30–32,36,38–41 whereas only a few used high‐resolution mass spectrometers 42–49 .…”

Rationale: Today, β-naphthol pigments are among the largest and most widely used classes of synthetic organic pigments. Their application fields range from textiles, food and beverages, printing inks, plastics to paint formulations. Most of the research dealing with their study using mass spectrometry focuses on developing sensitive methods for their quantification or their removal from industrial wastewater. Their qualitative recognition in formulations, whose composition is undisclosed by manufacturers, has not been tackled yet. Methods:The collision-induced dissociation fragmentation pathways of 10 red and orange widely used pigments of the late 19th to the early 20th centuries, belonging to the β-naphthol and Naphthol AS classes, were characterized using liquid chromatography/electrospray ionization quadrupole time-of-flight mass spectrometry in negative-ion mode. Results:The fragmentation pathways of these pigments were determined, and the pigments are discussed in relation to their chemical structures. The results were used to determine the composition in terms of the secondary components of one of our reference commercial formulations, characterized by a complex mixture of synthesis by-products. Conclusions:By coupling the high sensitivity of high-resolution mass spectrometry with an efficient chromatographic separation optimized for the analysis of β-naphthol dyes and pigments, we provided a method for the qualitative recognition of this class of molecules in unknown formulations possibly used in different kinds of industrial and synthetic products.
