Descripción general

For fast chromatography and LC-MS detection, LiChrosolv® hypergrade, a family of solvents especially optimized and tested for LC-MS suitability is most suitable. LiChrosolv® hypergrade solvents meet all the requirements of modern LC-MS ionization methods (ESI/ APCI – positive and negative mode). Due to their low level of ionic background and low ion suppression, LiChrosolv® hypergrade solvents ensure high reproducibility and high ionization efficiency.

Aplicación

LiChrosolv® hypergrade acetonitrile with 0.1% (v/v) formic acid is used as a mobile phase solvent in gradient elution of peptides by LC-MS/MS.[1][2][3]
The product is also featured in the method development for analysis of California list of pesticides in cannabis.

Características y beneficios

  • microfiltered by 0.2 µm filter
  • the most comprehensive application range due to the largest retention time range
  • analytical reliability due to the highest possible purity and a minimum signal-to-noise ratio
  • time and cost savings due to the best possible batch consistency, thus avoiding repetitive analysis

Questions

1–2 of 2 Questions  

  1. 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

  2. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
