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.

Application
- Extraction of neonicotinoids from honey samples along with acetonitrile using dispersive liquid-liquid microextraction (DLLME)
- Ultrasonic solvent extraction and clean-up of roasted coffee samples for the analysis of 7 pesticide residues by liquid chromatography-tandem mass spectrometry (LC-MS/MS)
- DLLME based additional pre-concentration of the sample extracts in the analysis of three amphenicols in food products of animal origin by HPLC with UV detection
- Removal of organic phase of the obtained soil sample extracts in the determination of two sulfonylurea herbicides using HPLC
- Testing of four extraction solvents in the development of a HPLC-amperometric detection based method for the analysis of three carbamate residues in liquid and solid food samples
- Extraction of metrafenone from vegetable samples by matrix solid-phase dispersion (MSPD method followed by HPLC analysis

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
