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.

Organic acid measurement complements wine quality assessment, influencing color and taste through fermentation control.
相关内容
The measurement of organic acids in wines is complementary to sensorial and microbiological quality assessment in fermentation control, for example, because the types and concentrations of the different acids influence the resulting color and taste of the wine.

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

What solutiuon can i use to clean this column?
1 answer-
Cleaning Procedure:
Metal contamination is indicated by shortened retention times and/or skewed peaks. Flush the column in the reverse flow direction following column-specific conditions listed below; do NOT connect the column to the detector during this process. Monitor the system closely to ensure that the maximum pressures are not exceeded. Note that up to 20% ethanol or up to 5% isopropanol may be substituted for the solvents recommended below.
SUPELCOGEL K Mobile Phase: 0.1M K2HPO4 Flow: 0.1 mL/min. Temperature: 85 °C Time: 4-16 hours
SUPELCOGEL Pb & 8 Pb Mobile Phase: 0.1M Pb(NO3)2 Flow: 0.1 mL/min. Temperature: 85 °C Time: 4-16 hours
SUPELCOGEL Ca & 8 Ca Mobile Phase: 0.1M Ca(NO3)2 at a pH of 6.3 Flow: 0.1 mL/min. Temperature: 85 °C Time: 4-16 hours
SUPELCOGEL H, C-610H, C-611, & 8H Mobile Phase: 10/90 CH3CN/0.01NH3PO4 Flow: 0.1 mL/min. Time: 3-4 hours at 25 °C
SUPELCOGEL Ag1 & Ag2 No recommended cleaning procedures.Any additional cleaning procedures are as a last resort to prolong the column life, because the addition of organic solvents will cause the resin to swell resulting in an increase in pressure. Monitor the system closely to insure that the maximum pressures are not exceeded. To remove organic contamination, pump the columns in reverse flow at 0.1 mL/min. with 5:95 acetonitrile:water at 25 °C for 4 hours.

How does the Supelcogel™ H differ from the Supelcogel™ C-610H?
1 answer-
Both the Supelcogel™ H and the Supelcogel™ C-610H are microparticulate, macroporous, polystyrene resin columns designed for ion exchange separation of organic acids, carbohydrates, sugar alcohols, and fermentation products. The C-610H is manufactured with a slightly higher cross linkage. Maximum temperature for the Supelcogel™ H is 90° C and for Supelcogel™ C-610H is 60° C. Of the two, only the Supelcogel™ H is available in the 25cm x 4.6mm hardware.
