Hello, I have a question regarding the use of Tenax as sampling medium. Acc. to DIN ISO 16000-6, VOCs in air can be determined using Tenax TA. Can you tell me whether Tenax TA can also be used to determine VOCs from CO2 or NOX gases?
1 answer-
The Tenax® Porous Polymer Adsorbent can be used for sampling volatile organic compounds from air and gas samples; therefore, it is applicable for determining VOCs from CO2 or nitrogen dioxide gases.

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
