General description

Los disolventes LiChrosolv® tienen un alto grado de transmitancia UV, un bajo recuento de partículas, baja acidez y alcalinidad y un bajo nivel de residuos de evaporación. Esto los hace ideales para separaciones reproducibles.

Application

Disolvente para aplicaciones de cromatografía como:
  • análisis de productos alimentarios de acuerdo con los métodos de la farmacopea de los Estados unidos (USP)
  • determinación por HPLC de productos alimenticios
  • extracción de sabores de lactona a partir de materias primas de ácidos grasos[1]
  • análisis de la vitamina A de matrices alimentarias fortificadas utilizando UHPLC[2]
  • extracción Soxhlet de materiales vegetales para separación cromatográfica[3]
  • cuantificación de vitaminas liposolubles mediante HPLC-MS[4]
  • detección de cannabinoides sintéticos (SC) en líquidos electrónicos utilizados en los cigarrillos electrónicos[5]
  • análisis de SC en muestras de sangre, orina y mezclas de hierbas[6]

Features and Benefits

  • envasado en botellas de vidrio
  • ofrece alta resolución, sensibilidad y una separación optimizada de la línea basal máxima

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
