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.

General description
Application
- Pressurized planar electrochromatography of DNS amino acids derivatives in silica gel and silanized silica gel systems with formic acid addition to the water mobile phase: This study explores the separation selectivity of dansyl (DNS) derivatives of amino acids using pressurized planar electrochromatography (PPEC) on Silica gel 60 TLC plates. The research demonstrates significant differences in separation selectivity between high-performance thin-layer chromatography (HPTLC) and PPEC systems, highlighting the electrophoretic effects in the PPEC system (Chomicki and Dzido, 2021).
- Thin-layer chromatography of DNS amino acids derivatives in systems with silica gel and silanized silica gel plates: This article presents investigations into the separation selectivity of DNS derivatives of amino acids on Silica gel 60 TLC plates. The study shows the impact of varying concentrations of acetonitrile in the mobile phase on the separation efficiency, providing valuable insights for optimizing analytical techniques in biochemical research (Chomicki and Dzido, 2022).
- Determination of β-blocking receptor drugs in silica gel TLC systems with the mobile phase containing surfactant: This research examines the retention and separation of β-blocking drugs on Silica gel 60 TLC plates using mobile phases with surfactants. The study assesses the effect of surfactant concentration on zone shape properties and provides a quantitative analysis of selected solutes, emphasizing the method′s environmental friendliness due to low propanol use (Traczuk and Polak, 2022).

How is shipping temperature determined? And how is it related to the product storage temperature?
1 回答-
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
