@jara_uaeh @LatinXChem Hello, thank you very much for your question

[Cesar Castro G @castro4207]

@a17_chris @LatinXChem Hola, gracias por tu pregunta. En este trabajo se utilizaron resinas SPE (HLB, MCX y C18). En mi grupo de investigación hemos trabajado con otras, la técnica de fijación es bastante estable. Se ha reutilizado hasta 24 veces sin pérdida significativa en la eficiencia de extracción

[Cesar Castro G @castro4207]

@LucyTeresa92710 @LatinXChem El método es bastante robusto. Sería necesario evaluar si algunos pasos de la extracción, como una limpieza diferente, requieren ajustes. Sin embargo, bastaría con validar el método para una nueva matriz de interés y, de ser necesario, analizar el efecto matriz en la muestra.

[Cesar Castro G @castro4207]

@LucyTeresa92710 @LatinXChem Gracias por su pregunta. Se eligieron estos detectores porque es más probable que los laboratorios dispongan de ellos, ya que los de LC-MS/MS son más costosos. Además, con los detectores seleccionados se pueden obtener LODs y LOQs comparables a los del LC-MS/MS, utilizando FLD

@mgabriellarg Negativo my friend, no como tu test, ese si que está bien positivo

@LucyTeresa92710 @LatinXChem @MethodsRSC @AnalysisSensing About regulations, there are currently none because these are emerging contaminants. These studies are a step towards assessing the conditions in which they exist in the environment, and eventually, regulations may be established.

Hi @LatinXChem! my work: 'Development and validation of 3D printed devices for the determination of non-steroidal anti-inflammatory drugs (NSAIDs) in water samples by chromatographic methods'
#LatinXChem23 #LatinXChemAna #Ana47 #analyticalchemistry @MethodsRSC @AnalysisSensing

[Cesar Castro G @castro4207]

@LucyTeresa92710 @LatinXChem @MethodsRSC @AnalysisSensing Yes, currently, efforts are underway to test with new groups of emerging contaminants and to expand the number of NSAIDs that can be monitored using this method.

[Cesar Castro G @castro4207]

@mbdessuy @LatinXChem @MethodsRSC @AnalysisSensing The devices were tested and were used up to 10 times without losing efficiency.

[Cesar Castro G @castro4207]

@mbdessuy @LatinXChem @MethodsRSC @AnalysisSensing Hello, thanks for your question. Selectivity is determined by the extraction resin present on the supports, which has an HLB that is compatible with NSAIDs. Additionally, mass detection was used in the chromatographic method, which helps identify the specific compounds.

[Cesar Castro G @castro4207]

@TaniaLizCruz @LatinXChem @MethodsRSC @AnalysisSensing Hello, very interesting question. Currently, these devices are only designed for small scales due to their capacity to extract from resins, and they are also expensive when considering large-scale production.
