主要特征
SILENT符合PM取样的要求,旨在对家庭环境中收集的粉尘进行化学表征:
非常低的噪音(35db),允许PM收集在卧室,教室,医院,博物馆,图书馆等;
在Æ47mm膜过滤器上收集PM,可进行后续化学分析;
PM2.5或PM10采样入口也可以收集粗粒(> 2.5mm或> 10mm);
流速:10升/分钟,能够确保收集足够的PM量,用于室内环境中PM浓度和成分的日常测量。
为了确保延长无人值守的采样周期,可以在顺序单元中安装多达4个进样口(每个进样口带有一个薄膜过滤器),并按所需顺序对循环进行编程。
MAIN CHARACTERICTICS
SILENT Sequential Air Sampler is a sequential instrument specifically developed for particulate matter collection in indoor environment.
SILENT meets the requirements of PM sampling aimed to the chemical characterization of the collected dust in domestic environments:
very low noise (35db), allowing PM collection also in bedrooms, classrooms, hospitals, museums, libraries, etc.;
PM collection on Æ 47mm membrane filters, allowing subsequent chemical analyses;
PM2.5 or PM10 sampling inlet with the possibility to collect also the coarse fraction (>2.5mm or >10mm);
flow rate: 10 l/min, able to assure the collection of a sufficient PM amount for the daily measurement of PM concentration and composition in indoor environments.
To assure extended unattended sampling periods, up to 4 inlets (each one carrying one membrane filter) can be installed in the sequential unit and programmed for cycles in the desired sequence.
