DS/EN ISO 18856 - WATER QUALITY - DETERMINATION OF SELECTED PHTHALATES USING GAS CHROMATOGRAPHY/MASS SPECTROMETRY Organization: DS
Date: 2005-10-26
Description: This International standard specifies a method for the determination of phthalates in water after solid phase extraction and gas chromatography/mass spectrometry. This method is applicable to the determination of phthalates (see Table 1) in ground water, surface water, wastewater and drinking water in mass concentrations ranging from above 0,02 µg/l up to 0,150 µg/l, depending on the individual substance and the value of the blank.
ASTM C1844 - STANDARD TEST METHOD FOR DETERMINATION OF URANIUM IN URINE BY INDUCTIVELY COUPLED PLASMA MASS SPECTROMETER FOLLOWING NITRIC ACID DILUTION Organization: ASTM
Date: 2016-12-15
Description: This test method covers the determination of uranium in urine by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) after dilution in nitric acid. The method is presented in two parts.
ASTM C1871 - STANDARD TEST METHOD FOR DETERMINATION OF URANIUM ISOTOPIC COMPOSITION BY THE DOUBLE SPIKE METHOD USING A THERMAL IONIZATION MASS SPECTROMETER Organization: ASTM
Date: 2018-02-01
Description: In case the uranium amount concentration of the double spike is known or certified, the uranium amount concentration of the sample can be determined using the isotope dilution mass spectrometry (IDMS) method as described in Test Method C1672, by blending the sample gravimetrically with the double spike and performing a DS measurement.
ASTM D6420 - STANDARD TEST METHOD FOR DETERMINATION OF GASEOUS ORGANIC COMPOUNDS BY DIRECT INTERFACE GAS CHROMATOGRAPHY-MASS SPECTROMETRY Organization: ASTM
Date: 1999-05-10
Description: The test method incorporates a performance-based approach, which validates each GCMS analysis by placing boundaries on the instrument response to gaseous internal standards and their specific mass spectral relative abundance. Using this approach, the test method may be extended to analyze other compounds.
DS/ENV 13070 - FRUIT AND VEGETABLE JUICES - DETERMINATION OF THE STABLE CARBON ISOTOPE RATIO (13C/12C) IN THE PULP OF FRUIT JUICES - METHOD USING ISOTOPE RATIO MASS SPECTROMETRY Organization: DS
Date: 1998-07-13
Description: The determination of this parameter is useful as an internal standard for comparison with the Carbon 13 content value obtained for the sugars.
