DIN EN ISO 10703 - WATER QUALITY - DETERMINATION OF THE ACTIVITY CONCENTRATION OF RADIONUCLIDES - METHOD BY HIGH RESOLUTION GAMMA-RAY SPECTROMETRY (ISO 10703:2007) Organization: DIN
Date: 2015-12-01
Description: Samples with activities typically between 1 Bq and 104 Bq can be measured as such, i.e. without dilution or concentration of the sample or special (electronic) devices.
DS/EN ISO 15088 - WATER QUALITY - DETERMINATION OF THE ACUTE TOXICITY OF WASTE WATER TO ZEBRAFISH EGGS (DANIO RERIO) Organization: DS
Date: 2009-01-08
Description: This International Standard specifies a method for the determination of degrees of dilution or concentrations as a measure of the acute toxic effect of waste water to fish eggs within 48 h.
DSF/ISO/FDIS 17378-2 - WATER QUALITY ? DETERMINATION OF ARSENIC AND ANTIMONY ? PART 2: METHOD USING HYDRIDE GENERATION ATOMIC ABSORPTION SPECTROMETRY (HG-AAS) Organization: DS
Description: Samples containing arsenic at higher concentrations than the application range can be analysed following appropriate dilution [1]. The linear dynamic range of this method is approximately 0,5 ìg/l to 100 ìg/l when using a continuous flow system.
DS/ISO/TS 19620 - WATER QUALITY – DETERMINATION OF ARSENIC(III) AND ARSENIC(V) SPECIES – METHOD USING HIGH PERFORMANCE LIQUID CHROMATOGRAPHY (HPLC) WITH DETECTION BY INDUCTIVELY COUPLED PLASMA MASS SPECTROMETRY (ICP-MS) OR HYDRIDE GENERATION ATOMIC FLUORESCENCE SPECTROMETRY (HG-AFS) Organization: DS
Date: 2018-01-16
Description: Samples containing arsenic at concentrations higher than the linear dynamic range can be analysed after suitable dilution. This method is based on high performance liquid chromatography separation of arsenic species with either inductively coupled mass spectrometry (ICP-MS) or hydride generation atomic fluorescence spectrometry (HG-AFS) as a method of detection.
ISO - ISO 6145-2 - GAS ANALYSIS - PREPARATION OF CALIBRATION GAS MIXTURES USING DYNAMIC METHODS - PART 2: PISTON PUMPS - SECOND EDITION Organization: ISO
Date: 2014-08-15
Description: ISO 6145 comprises a series of International Standards dealing with various dynamic methods used for the preparation of calibration gas mixtures. This part of ISO 6145 describes a method and preparation system using piston pumps. The mixture composition and its associated uncertainty are based on calibration of the piston pumps by dimensional measurements.
