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.

General description
Application
- Detection and quantification of butanol and its isomers in paint samples by a rapid fast gas chromatography-proton transfer reaction-mass spectrometer (FastGC-PTR-MS) method
- Simultaneous assessment of 121 VOCs emitted from 41 cellulose acetate movie films by proton transfer reaction-time-of-flight-mass spectrometry (PTR-ToF-MS)
- As an internal standard in the determination of n-butane and its metabolites in the blood, heart, and tissue samples of three autopsy cases that died due to sniffling n-butane and isobutane from portable gas cartridges
- Headspace-single drop microextraction (HS-SDME) of VOCs from different types of tomato samples for their quantification by gas chromatography-flame ionization detection (GC-FID)

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.
