CARACTERÍSTICAS
BIOCOMBUSTIBLES
Nuestra cartera de disoluciones de biocombustible multicomponente está diseñada específicamente para su uso con ASTM® D6584. Estas disoluciones previamente preparadas ahorran al analista un valioso tiempo de preparación. Consta de disoluciones de material de referencia certificado (CRM) producidas y certificadas según la ISO 17034 y la ISO/IEC 17025. Algunos de nuestros patrones de biocombustible también están disponibles como productos alternativos más ecológicos. Estos productos reducen el impacto medioambiental sin comprometer la calidad ni la eficacia de sus resultados.
Los bajos niveles de glicerina libre y unida son fundamentales para el rendimiento del combustible biodiésel. Pero tanto la glicerina libre como la glicerina unida contribuyen a la formación de depósitos en las boquillas de los inyectores, los pistones, las válvulas, los filtros y los tanques de almacenamiento. La ASTM D6584 proporciona un método normalizado para la determinación de la glicerina libre y la glicerina total (libre + unida). Los productores de biodiésel comercial utilizan este método para determinar si puede venderse un ciclo de producción de B100 (100 % de ésteres metílicos de biodiésel) o requiere rectificación.
GASOLINA Y DIÉSEL
Ofrecemos CRM para cuantificar el queroseno, la gasolina y los compuestos aromáticos como el benceno. Están diseñados para utilizarse con los métodos ASTM respectivos: ASTM D1319, ASTM D5880 y ASTM 4053.
COMBUSTIBLES E HIDROCARBUROS
Para determinar los hidrocarburos en aceites, crudos, refinados u otras matrices, ofrecemos una gama de materiales de referencia puros y en disolución. La selección incluye patrones analíticos y patrones de calidad de material de referencia certificados con idoneidad para cromatografía de gases (GC) y cromatografía líquida de alta presión (HPLC).
CRM DE MATRIZ DE AZUFRE
Nuestra selección de CRM de azufre incluye productos de Paragon Scientific adecuados para calibración, verificación o uso en procedimientos de control de calidad que implican análisis del contenido de azufre en los productos petrolíferos. Nuestra gama incluye azufre en aceite mineral ligero, aceite mineral pesado, diésel sintético y en queroseno (inodoro) con un contenido de azufre que oscila entre el 0 % (blanco) y el 5,0000 % (50000 ppm) para cada material. Todos Los productos están certificados en conformidad con la ISO/IEC 17025 y la ISO 17034 y son totalmente trazables a las normas internacionales. Se suministran en volúmenes de 100 ml en envases de vidrio a prueba de manipulación con una vida útil de 12 meses.
