Descripción general

EPA 552.2 Haloacetic Acids Mix is a multi-component solution containing bromoacetic acid, bromochloroacetic acid, bromodichloroacetic acid, chloroacetic acid, dibromochloroacetic acid, dibromoacetic acid, dichloroacetic acid, tribromoacetic acid, and trichloroacetic acid as certified reference materials (CRMs). The raw materials and solvents used in the preparation of EPA 552.2 Haloacetic Acids Mix have been screened for identity and purity. The mixture is gravimetrically prepared and quantitatively analyzed by gas chromatography (GC).
US EPA 500 Series methods are analytical methods for identifying and quantifying organic contaminants such as volatile organic compounds (VOCs), pesticides, synthetic organic compounds (SOCs), and trihalomethane disinfection byproducts (THMs) in raw source water, finished drinking water, and drinking water at all stages of treatment.

Aplicación

EPA Method 552.2 Haloacetic Acids Mix is used as a CRM to quantify halogenated carbonaceous disinfection by-products (C-DBPs) in drinking water,[1][2] tap water,[3] treated water,[4] and wastewater samples[5] by gas chromatography (GC) based techniques.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Otras notas

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
