    IDFL consults with clients by conducting traceability audits of supply chains primarily for CSR topics like live plucking. IDFL consults or performs audits under different licenses such as the following: IDFL internal standard, this standard began in 2008 and has gone through different revisions since.

  3. Internal standard - Wikipedia

    en.wikipedia.org/wiki/Internal_standard

    In NMR spectroscopy, e.g. of the nuclei 1 H, 13 C and 29 Si, frequencies depend on the magnetic field, which is not the same across all experiments. Therefore, frequencies are reported as relative differences to tetramethylsilane (TMS), an internal standard that George Tiers proposed in 1958 and that the International Union of Pure and Applied Chemistry has since endorsed.

  4. Ion suppression in liquid chromatography–mass spectrometry

    en.wikipedia.org/wiki/Ion_suppression_in_liquid...

    It is important that the internal standard displays very similar (ideally identical) properties, with respect to detector response (i.e. ionisation), as the analyte of interest. To simplify the selection of internal standard, most laboratories use an analogous stable isotope in an isotope dilution type analysis. The stable isotope is almost ...

  5. ISA 400 Risk Assessments and Internal Control - Wikipedia

    It serves to require the auditor to understand the client's accounting system and internal control system and to assess control risk and inherent risk. The objective is to determine the nature, timing and extent of substantive procedures in order to reduce audit risk to an acceptable low level.

    The AICPA auditing standard Statement on Standards for Attestation Engagements no. 18 (SSAE 18), section 320, "Reporting on an Examination of Controls at a Service Organization Relevant to User Entities' Internal Control Over Financial Reporting", defines two levels of reporting, type 1 and type 2. Additional AICPA guidance materials specify ...

    This is a list of the International Financial Reporting Standards (IFRSs) and official interpretations, as set out by the IFRS Foundation. It includes accounting standards either developed or adopted by the International Accounting Standards Board (IASB), the standard-setting body of the IFRS Foundation.

  9. Isotope dilution - Wikipedia

    en.wikipedia.org/wiki/Isotope_dilution

    Mixing of the isotopic standard with the sample effectively "dilutes" the isotopic enrichment of the standard and this forms the basis for the isotope dilution method. Isotope dilution is classified as a method of internal standardisation, because the standard (isotopically enriched form of analyte) is added directly to the sample. In addition ...
