Dichlorobenzene. Determination in air
Дихлорбензол. Определение содержания в воздушной среде
Status: Effective - Introduced for the first time. IUS 9-2014
This standard establishes a procedure for sampling air and measuring the mass concentration of dichlorobenzene (any isomer) by gas chromatography - mass spectrometry (GC - MS). The method is used for concentrations of 2 - 50 ppbv (part per billion by volume = one billionth by volume), and it usually requires saturation by concentrating the sample with a volume of 1 l. The detection limit is 0.5 ppbv. The use of the described method is acceptable for most ambient air sampling conditions into the adsorbing container. During sampling, the use of solid adsorbents instead of containers is allowed or sampling is carried out by direct automated entry into the chromatograph.
Настоящий стандарт устанавливает процедуру для отбора проб воздуха и измерения массовой концентрации дихлорбензола (любого изомера) методом газовой хроматографии - масс-спектрометрии (ГХ - МС). Метод применяют для концентраций 2 - 50 ppbv (part per billion by volume = одна миллиардная по объему), и он, как правило, требует насыщения путем концентрирования пробы объемом 1 л. Предел обнаружения составляет 0,5 ppbv. Использование описанного метода приемлемо для большинства условий пробоотбора окружающего воздуха в адсорбирующий контейнер. При проведении отбора проб допускается использование твердых адсорбентов вместо контейнеров или отбор проб проводят путем прямого автоматизированного ввода в хроматограф
