General description

SupraSolv® ECD and FID is specially developed for gas chromatography in combination with ECD (Electron Capture Detector) and FID (Flame Ionization detector). SupraSolv® solvents offer the largest specified retention time range, a clear baseline and a minimum signal-to-noise ratio leading to reliable and reproducible analysis results.

Application

Ideal for GC applications including sensitive detection in residue and environmental analysis.
The product is reported for used as a solvent in analyses of:
  • commercial technical mixtures (aroclors) and in environmental samples for polychlorinated dibenzo-p-dioxins (PCDD), polychlorinated dibenzofurans (PCDF) and polychlorinated biphenyls (PCB) by high resolution gas chromatography coupled to electron capture detector (HRGC-ECD)[1]
  • sewage and soil samples for PCB congeners using HRGC-ECD or HRGC in conjunction with high resolution mass spectrometry (HRMS)[2]

Specifications

Saturation Concentration in Air: 239 g/m3 (20 °C)

Other Notes

Questions

1–2 of 2 Questions  
  1. 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

  2. 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.
