Application

Alkane standard mixture has been used as a retention index calibration standard in the metabolic analysis of body fluids of humans and vertebrates using gas chromatography coupled with mass spectrometry (GC-MS).
It may also be used for performance tests of GC-systems as per DIN ISO 9377-2:2000 method used for the determination of petroleum hydrocarbons in water samples by gas chromatography technique.[1]
Alkane standard mixture has been used as a retention index calibration standard in the metabolic analysis of body fluids of humans and vertebrates using gas chromatography coupled with mass spectrometry(GC-MS).[2]
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Questions

1–2 of 2 Questions  
  1. Good morning Is the 68281-2ml Alkane standard mixture for performance product covered by ISO 17034 accreditation? If so, what documentation does this show? there is no evidence in the Certificate of Analysis

    1 answer
    1. This is a an analytical standard and not a Certified Reference Material. Therefore it has no ISO 17034 accreditation. An Alkane Standard that will have ISO 17034 accreditation is the C7 - C40 Saturated Alkanes Standard, certified reference material - 49452-U, https://www.sigmaaldrich.com/US/en/product/supelco/49452u.

  2. Bonjour, Nous comprenons que les alcanes sont individuellement à 50mg/L, est ce bien le cas ?

    1 answer
    1. Yes, each n-alkane is included individually at 50 mg/L, as stated on the Certificate of Analysis. This product includes even alkanes from C10 to C40. Please see the link below to review a sample Certificate of Analysis.
