Estándares de espectroscopia
Los estándares de espectroscopía son materiales de referencia críticos utilizados para determinaciones espectroscópicas precisas y fiables. Esta categoría incluye una variedad de estándares esenciales para diferentes técnicas espectroscópicas, como los estándares de absorción atómica y los estándares de emisión atómica, que son vitales para la medición precisa de concentraciones de metales. Además, la categoría abarca estándares para resonancia de espín, cruciales para la espectroscopia de resonancia de espín electrónico (ESR) y la espectroscopia de resonancia magnética nuclear (NMR), asegurando la calibración y validación precisas de estos instrumentos. También se incluyen estándares de espectrofotometría, proporcionando puntos de referencia para el análisis cuantitativo de la absorción de luz en diversas muestras. Estos estándares juegan un papel fundamental en garantizar la precisión, consistencia y reproducibilidad de las mediciones espectroscópicas en numerosas aplicaciones científicas e industriales, incluyendo el análisis ambiental, las pruebas farmacéuticas y la investigación de materiales. Al ofrecer materiales de referencia de alta pureza, los estándares de espectroscopía apoyan el desarrollo de métodos analíticos fiables y el mantenimiento de rigurosos protocolos de control de calidad.
