Met One 的形态取样器旨在符合并超过 EPA 形态要求。两种型号提供合规性监测选择：SASS，5 通道采样系统；和 SUPER SASS，一个 8 通道、多事件、采样系统。SASS 符合**初的 EPA 要求，而 SUPER SASS 增加了州和地方当局建议的好处。两种型号均使用 Met One Instruments 首创的概念，例如无污染罐、太阳辐射防护罩和模块化设计。SASS 和 SUPER SASS 不仅符合 EPA 规范，而且超过了规范；正如 EPA 和加州空气资源委员会实地研究所证明的那样。
便携式集成环境颗粒物采样系统
PM 2.5入口， 采样率为 6.7 升/分钟
太阳能防护罩可将暗盒的温度保持在低于环境温度的 5°C 以下
罐提供数据完整性 - 防污染
新的多细胞剥离器和多种过滤介质
该单元提供 SASS 的所有功能，并具有顺序编程以允许多天操作。SUPER SASS **多可以采样八天，具体取决于每天使用的采样通道数。SUPER SASS 标配四个独立的体积流量控制器，每个采样器组一个。
多达 8 个通道操作
一到八天的采样，顺序
自动体积流量控制器
每个通道可以独立操作
高级现场审核屏幕
SASS 和 SUPER SASS 基于经过 8 年现场测试和 3 年 EPA 计划测试的设计。该测试证明了这一概念并有助于改进设计。
这两款产品专为移动中的程序而设计，具有出色的灵活性和便携性。SASS和SUPER SASS由便携式泵箱、三脚架、样品头和控制器组成，携带方便，安装方便。安装时间不到一小时。
SASS 允许在实验室中执行所有关键维护。其他仪器因必须在现场进行维修而受到入口、歧管和 PM 2.5分离器的污染。使用集成罐，每次更换样品时，都会清洁与采样气流接触的采样器的每个元件。
样品罐与空白过滤盒一起装入实验室。密封罐被运送到物种形成现场进行部署。暴露后，罐被密封以运送到实验室。这种方法避免了由于样品的现场处理而造成的污染。
SASS 采用对流太阳辐射防护罩，将样品保持在环境温度的 5°C 范围内。
经过现场和实验室测试的 PM 2.5 入口
每个采样罐都集成了流量为 6.7 升/分钟的 Sharp Cut Cyclone (SCC)，以去除空气动力学直径大于 2.5 μm 的颗粒。可根据要求提供测试报告。
样品罐包含 SCC 和所有必要的组件，用于排除空气动力学直径大于 2.5 μm 的颗粒、去除干扰气体和收集包括半挥发性颗粒在内的颗粒。采样罐设计用于容纳剥离器和一个或两个过滤器，用于半挥发性物质的采样，以及用于收集硝酸、氨和甲酸等气体。例如，Teflon Nylon 过滤器对可以在硝酸过滤器后面运行，以在同一盒中包含无机离子和硝酸盐。滤罐可按如下方式使用：(1) 用于质量和痕量金属的 Teflon 过滤器，(2) 通过离子色谱分析无机离子的 Teflon 或 Quartz，(3) 用于硝酸盐的裸露尼龙或浸渍过滤器，(4) Tandem Quartz，用于有机和元素碳，带有用于文物收集的备用过滤器，

英文原文：
Met One’s Speciation Samplers are designed to comply with and exceed EPA Speciation requirements. Two models provide a choice for compliance monitoring: SASS, a 5 channel sampling system; and SUPER SASS, an 8 channel, multiple event, sampling system. The SASS conforms to original EPA requirements and SUPER SASS adds benefits suggested by state and local authorities. Both models use concepts pioneered by Met One Instruments, such as the contamination free Canister, solar radiation shield, and modular design. SASS and SUPER SASS not only comply to EPA specifications, they exceed the specifications; as proven in EPA and California Air Resources Board field studies.

Portable integrated ambient particulate sampling system
Inlet for PM2.5 at 6.7 liter/minute sample rate
Solar shield maintains cassettes to less than <5°C over ambient temperature
Canister provides data integrity – contamination proof
New multi-cell denuder and multiple filter medias
This unit offers all the features of the SASS plus it has sequential programing to allow multiple day operation. SUPER SASS will sample up to eight days depending on the number of sample channels used per day. SUPER SASS comes standard with four independent volumetric flow controllers, one for each sampler group.
One to Eight day Sampling, Sequential
Automatic Volumetric Flow Controllers
Each Channel may be operated independently
Advanced Field Audit Screens
The SASS and SUPER SASS are based on designs that have been field tested for eight years with 3 years of testing in the EPA program. This testing has proven the concept and helped to refine the design.
Designed for programs on the move, both units offer superior flexibility and portability. SASS and SUPER SASS are composed of a portable pump box, tripod, sample head and controller, they are easy to carry and easy to install. Installation takes less than one hour.
The SASS allows all critical maintenance to be performed in the lab. Other instruments suffer contamination of inlet, manifold and PM2.5 separator because they must be serviced in the field. With the integrated canister every element of the sampler that is contacted by the sampled air stream is cleaned with each sample change.
Sample Canisters are loaded in the lab with blank filter cassettes. Sealed canisters are shipped to speciation field sites for deployment. After exposure, the canisters are sealed for shipment to the lab. This approach circumvents contamination due to field handing of the sample.
SASS incorporates a convective solar radiation shield to maintain the samples within 5°C of ambient temperature.
A Sharp Cut Cyclone (SCC) with a flow of 6.7 liters/min is integrated in every sampling canister to remove particles larger than 2.5 μm aerodynamic diameter. Test report available upon request.
The sample canister contains the SCC and all necessary components for excluding particles above 2.5 μm aerodynamic diameter, for removing interfering gases, and for collecting particles including semi-volatile. The sampling canisters are designed to accommodate denuders and one or two filters for sampling of semi-volatile species, and for collection of gases such as nitric acid, ammonia, and formic acid. For example, a Teflon Nylon filter pair can be operated behind a nitric acid denuder to include inorganic ions and nitrate in the same cassette. Canisters can be used as follows: (1) Teflon filter for mass and trace metals, (2) Teflon or Quartz for inorganic ions by ion chromatography, (3) Denuded Nylon or impregnated filter for nitrate, (4) Tandem Quartz for organic and elemental carbon, with backup filter for artifact collection, (5) Denuded carbon-impregnated filter for semi-volatile organic compounds.
