Disolventes Ultra Puros ROMIL-UpS™

La mejor calidad para las técnicas con guión

Mientras que los niveles de pureza de los disolventes de ROMIL-SpS™ son adecuados para la mayoría de las aplicaciones instrumentales, existen algunas técnicas de alta sensibilidad que exigen una pureza aún mayor. Los instrumentos analíticos pueden ahora detectar sustancias en concentraciones tan bajas que antes se consideraban indetectables. Esto es especialmente cierto en el análisis ambiental, donde la detección de trazas de contaminantes es ahora la rutina.

Las técnicas con guiones, en particular, suponen una gran carga para la pureza de los disolventes. Estos sistemas de doble o triple detección requieren una calidad de disolvente adaptada a las necesidades de todos los detectores configurados.

ROMIL-UpS™ Los disolventes de pureza ultra alta han sido desarrollados para cumplir con este requisito. Las técnicas de purificación son más exigentes y cada lote se prueba cuidadosamente para asegurar el mejor rendimiento posible. El producto se embotella en botellas que han sido especialmente pretratadas para asegurar que las impurezas metálicas residuales se mantienen tan bajas como cuando se fabrican recién. Así, no sólo se controla la pureza original, sino también la pureza real cuando se abre un tiempo después.

Porque no importa cuán puro sea el solvente, eventualmente se degradará con el tiempo. Estos productos de degradación pueden aparecer durante el uso, ya sea como picos adicionales o a través de una reacción no deseada e inesperada con la muestra. En ROMIL hemos encontrado que cuanto más puro sea el disolvente, más tiempo será útil su `estabilidad'. Nuestra experiencia se destila en cada botella de disolvente ROMIL-UpS™ lo que significa una mayor garantía de resultados de calidad, a la primera, cada vez.

Applications
ROMIL-UpS™
  • Liquid Chromatography-Mass Spectrometry

    Liquid chromatography paired with mass spectrometry (LC-MS) is an extremely sensitive technique and therefore requires solvents of the ultimate purity. ROMIL‑UpS ultra lc products are purified to meet the stringent criteria demanded by analysts. They feature:

     

    • Suitability testing for LC-MS
    • Extremely low levels of ionic impurities
    • Minimal baseline drift

     

    ROMIL‑UpS ultra-lc solvents are compatible with ESI/APCI ionisation methods in both positive and negative modes. Additionally, their low ionic background resulting in low ion suppression make ROMIL‑UpS solvents the ultimate choice.

  • Liquid Chromatography-Inductively Coupled Plasma-Mass Spectrometry

    The coupling of liquid chromatography with ICP-MS (LC-ICP-MS) offers many advantages for speciation analysis. With background ionic impurities controlled to low ppb levels, ROMIL‑UpS ultra lc solvents are eminently suited to this triple hyphenated technique.
  • Ultra High Performance Liquid Chromatography

    In contrast to traditional HPLC, Ultra High Performance Liquid Chromatography (UHPLC) combines sub 2 micron particles in smaller diameter columns of shorter length on higher pressure instrumentation enabling enhanced resolution and efficiency of chromatographic separation. Although the resulting lower flow rates and shorter run times require less solvent, the purity demands on the solvent are increased. ROMIL‑UpS ultra lc solvents have the performance to more than play their part.
  • Gas Chromatography-Mass Spectrometry

    The Gas Chromatography-Mass Spectrometry (GC-MS) technique requires volatile organic solvents such as dichloromethane, hexane, methanol, acetonitrile and ethyl acetate. ROMIL‑UpS ultra gc versions of these solvents are carefully distilled in glass to produce the ultimate purity and are use tested for GC-MS, GC-ECD and GC-FID.
  • Gas Chromatography-Inductively Coupled Plasma-Mass Spectrometry

    Coupling of gas chromatography with ICP-MS permits the simultaneous determination of many elements. The hyphenated technique is particularly suited to the speciation of a number of metals, including lead, mercury and zinc. By virtue of the purification technique ROMIL‑UpS ultra gc solvents feature metallic levels in the low ppb range which makes them ideal for use in GC-ICP-MS.
