Descripción general

Las columnas fabricadas a base de sílice SUPELCOSIL LC-NH2 separan monosacáridos, disacáridos y algunos trisacáridos, con un orden de elución generalmente según el aumento de peso molecular. La retención disminuye a medida que se incrementa la proporción de agua:acetonitrilo en la fase móvil. Para más información solicite T397126 (Azúcares en columnas SUPELCOSIL LC-NH2)
The amino column is most often employed for the separation of mono- and disaccharides. As a normal phase application, amino columns have found use in the petroleum industry for class-type separations.

An analytical method was developed and validated for the determination of maltodextrin in raw milk, using high-performance liquid chromatography with evaporative light scattering detection. Maltodextrin content was evaluated in adulterated raw milk using a Supelcosil LC-NH2 (25cm×4.6mm) column and isocratic

Ibuprofen arginate is a rapidly absorbed salt designed to promote more rapid onset of analgesia than commercially available forms of ibuprofen. Ibuprofen and arginine have very different polarities and this becomes in a chromatographic problem, further complicated with the determination

The degradation fo steroid glycoalkaloids (SGAs) has been studied in model solutions. The number of colony forming units (CFU) was determined using a nondirect (cultivation) method during all stages of fermentation. The changes in SGAs content were observed by HPLC

Questions

1–3 of 3 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.

  3. Is the 25:75 water:acetonitrile used in the test for 58338 SUPELCOSIL™ LC-NH2 measured by volume or by weight?

    1 answer

    1. Volume to volume measurement is used when making the mobile phases.
