Application

Headspace vial may be used for the following:
  • In the determination of partition coefficient of ethyl acetate in water at 0° C from independent analyses of the total amount of ethyl acetate present in the vial, by automatic equilibrium headspace gas chromatography and vapor phase calibration (VPC).[1]
  • It may be used in the analysis of volatile polar residual solvents present in pharmaceutical products, during development and optimisation of headspace SPME method by GC-MS.[2]
  • It may also be used in the isotopic analysis of 18O in the leaf water of C3 and C4 grasses, during establishing a grassland signature in veins, as it was found that grasses with different photosynthetic pathway have different interveinal differences.[3]
  • It may also find application, in investigating metabolism by Pseudomonas fluorescens of volatile haloaliphatic hydrocarbons like 1,2-dichloroethane and 1,2-dichloropropane, which are some of the major contaminants of underground aquifers.[4]

General description

These vials require a special cap with an 18 mm thread. The standard 18-400 threaded caps will not fit this vial. The part numbers for caps that are available for these vials are SU860101(with PTFE/silicone, 1.3 mm thick), SU860102 (with PTFE/butyl, 1.6 mm thick), and SU860103 (with PTFE/silicone, 1.5 mm thick). These caps are made from stainless steel and are magnetic.

We show that 18O evaporative enrichment of bulk leaf water in grass species can be significantly more enriched than predicted by the Craig-Gordon model, with C4 grasses considerably more enriched than C3 grasses. Our results suggest that the unanticipated 18O

A Pseudomonas fluorescens strain designated PFL12 was isolated from soil and water that were contaminated with various chloroaliphatic hydrocarbons. The isolate was able to metabolize 1,2-dichloroethane, 1,1,2-trichloroethane, 1,2-dichloropropane, 2,2-dichloropropane, and trichloroethylene.

Mejora de la determinación de los compuestos orgánicos volátiles en el agua mediante SPME y GC/MS: norma ISO 17943

Se probaron el alto rendimiento, la fiabilidad y la reproducibilidad de la microextracción en fase sólida en espacio de cabeza (HS-SPME) en combinación con cromatografía de gases/espectrometría de masas (GC/MS) para la determinación de los compuestos orgánicos volátiles (COV) en agua en un ensayo interlaboratorio. La nueva ISO 17943 en la que se utiliza HS-SPME supone una mejora de los métodos oficiales existentes para esta determinación en cuanto a sensibilidad y selectividad.

Improved Determination of Volatile Organic Compounds in Water by SPME and GC/MS: ISO Standard 17943

High performance, reliability, and reproducibility of HS-SPME in combination with GC/MS for the determination of VOCs in water was proven in an interlaboratory trial. The new ISO 17943 using HS-SPME is an improvement on existing official methods for this determination in terms of sensitivity and selectivity.

Questions

1–4 of 4 Questions  

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

    1 answer

    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. Can the vials withstand cryogenic freezing or temperatures as low as -80°C?

    1 answer

    1. These vials are not suitable for cryogenic freezing temperatures and cannot withstand -80 °C.

      Helpful?

  3. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. 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
