Application

Adequado para HPLC, espectrofotometria, testes ambientais
O diclorometano pode ser usado nos seguintes casos:

  • Extração de neonicotinoides de amostras de mel junto com acetonitrila usando microextração líquido-líquido dispersiva (DLLME)
  • Extração com solvente ultrassônico e limpeza de amostras de café torrado para a análise de 7 resíduos de pesticidas por cromatografia líquida-espectrometria de massa em tandem (LC-MS/MS)
  • Pré-concentração adicional baseada em DLLME dos extratos de amostra na análise de três anfenicóis em produtos alimentícios de origem animal por HPLC com detecção de UV
  • Remoção da fase orgânica dos extratos de amostra de solo obtidos na determinação de dois herbicidas de sulfonilureia usando HPLC
  • Teste de quatro solventes de extração no desenvolvimento de um método baseado em detecção amperométrica por HPLC para a análise de três resíduos de carbamato em amostras de alimentos líquidos e sólidos
  • Extração de metrafenona de amostras de vegetais por dispersão de matriz em fase sólida (método MSPD) seguida de análise por HPLC

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
