A new method was established for the determination of extractable flame retardants from textile, foam, leather and plastic test specimens. The flame retardants were extracted with toluene from test specimens using ultrasonic assisted extraction with extraction time of 60 min at 60 ºC. Flame retardants were separated on a DB-XLB column using gas chromatography mass spectrometry (GC-MS) with helium (99.9 %) as carrier gas. One target and two qualifier ions were selected for target analyte under SIM/SCAN mode. Pre-treatment parameters were optimized, including the type of extractant, extraction...

A rapid method was developed for detecting biocides in textiles that come into direct contact with human skin, as recently regulated biocides lack validated testing methods. The method focuses on analyzing four biocides: MIT, CIT, OIT, and Triclosan. Textile samples were extracted using methanolic sonication, purified through centrifugation and filtration, and analyzed using a C18 column with 0.4% acetic acid: methanol (1:1 v/v) under isocratic conditions at 280 nm wavelength. Extraction parameters were optimized, and the calibration curve showed strong linearity (r² 0.9995) in the range...

Recently regulated phthalates do not have validated methods for testing hence their presence cannot be estimated in the consumer products. So, a rapid, sensitive and reliable method was developed for the separation and quantitative analysis of all 28 regulated phthalate contents from the childcare items, toys, and textile test specimens. Test specimens were extracted in tetrahydrofuran at 60 ºC and 60 min sonication and purified by centrifugation and filtration. Phthalate contents were separated on a DB-5MS column using helium gas as mobile phase under Sim/Scan mode. Pre-treatment factors...

Azo dyes are widely used due to their vibrant colors and compatibility with various substrates, but their reductive cleavage releases toxic aromatic amines. Existing quantification methods have limitations in applicability and simultaneous detection. This study presents a modified GC-MS method to analyze 28 amines and two internal standards in a single run, with UFLC confirmation. The method applies to diverse matrices, including liquid and powder dyes, textiles, and leather, eliminating the need for separate protocols. Recovery was 85%-115%, with linearity (R² = 0.994-0.996), a calibration...

Azofarbstoffe sind aufgrund ihrer leuchtenden Farben und ihrer Kompatibilität mit verschiedenen Substraten weit verbreitet, doch bei ihrer reduktiven Spaltung werden toxische aromatische Amine freigesetzt. Bestehende Quantifizierungsmethoden weisen Einschränkungen bei der Anwendbarkeit und dem gleichzeitigen Nachweis auf. In dieser Studie wird eine modifizierte GC-MS-Methode vorgestellt, mit der 28 Amine und zwei interne Standards in einem einzigen Durchgang analysiert und mit UFLC bestätigt werden können. Die Methode ist auf verschiedene Matrices anwendbar, darunter flüssige und...

Les colorants azoïques sont largement utilisés en raison de leurs couleurs vives et de leur compatibilité avec divers substrats, mais leur clivage réducteur libère des amines aromatiques toxiques. Les méthodes de quantification existantes présentent des limites en termes d'applicabilité et de détection simultanée. Cette étude présente une méthode GC-MS modifiée pour analyser 28 amines et deux étalons internes en une seule fois, avec confirmation UFLC. La méthode s'applique à diverses matrices, y compris les colorants liquides et en poudre, les textiles et le cuir, éliminant...

Newly regulated toxicants like flame retardants, phthalates, biocides (MIT, CIT, OIT, Triclosan), ortho-phenylphenols, DMFu, and azo dyes lack certified testing methods, making detection in consumer products difficult. To address this, sensitive and rapid analytical techniques were developed for textiles, foam, leather, and plastics. Samples were extracted using an organic solvent at 60°C for 60 min with sonication, followed by centrifugation and filtration. Toxicants were analyzed using GC/MS with a DB-5MS column and helium gas or UFLC. Extraction conditions were optimized, achieving good...

This study introduces a novel method for the simultaneous identification and quantification of extractable chlorinated organic carriers (COCs) from textiles, foam, and leather. Using dichloromethane under ultrasonic conditions at 25°C for 30 minutes, COCs were effectively extracted and analyzed via gas chromatography-mass spectrometry (GC-MS) with a DB-5MS column. The optimized method achieved high recoveries (95-105%), excellent precision (RSD <10%), and a low detection limit (<0.1 ng mL ¹). Real specimen analysis confirmed COCs at 2.60-9.94 ng mL ¹, highlighting the method's potential...
