扩散采样管

SPME FFA扩散采样手柄（DFH）能用于测定空气中VOCs的时间加权平均浓度值。通过分子扩散及吸附机理，将VOCs萃取富集至萃取头。与传统SPME取样将萃取头全部伸出针外不同，扩散采样是将萃取头缩回针中一段已知的距离。

radiello 扩散主体空气采样器该扩散主体设计用于在采样时容纳 Radiello 小柱吸附剂。该扩散主体的一端有螺纹，用于方便地连接到 Radiello 三角支撑板上。与大多数的小柱吸附剂不同，扩散主体可重新使用，并且在不使用时可使用温和的洗涤剂清洗。该扩散主体将收集粉尘（尤其在室外采样时），建议使用 4-5 次之后更换。 radiello™ 麻醉气体和蒸气采样器该套件开发用于外科手术室中一氧化二氮、异氟烷、乙氟醚、氟烷和七氯烷的采样。一整套采样器的部件使用一个密封的无菌袋单独包装。每包 10 个无菌袋。各无菌袋包含：1 件渗透性主体1 件支撑板1 件竖直连接头1 件吸附小柱有多种不同的 Radiello 小柱吸附剂。其中的每一种都特定用于不同类别化合物的采样。各小柱的尺寸为 60mm 长×4.8 或 5.8mm 直径。各小柱的设计为一次性使用，但 Radiello 热解吸 (TD) 小柱吸附剂除外。 发货时，各小柱包在透明热封聚乙烯 (PE) 袋子里的密封玻璃或塑料管中。同样的密封管可用于在解吸/分析之前储存采样后的小柱。每包小柱包括足够数量的自粘条形码标签，用于方便地记录采样日期和时间。 注：要使用 Radiello 系统进行空气的采样，除了小柱吸附剂还必须订购（单独）Radiello 扩散主体和三角支撑板。Radiello 入门套件 (RADxxxS) 包括完成采样所需的所有部件。Unique 3D radial design is not prone to face velocity effects and delivers higher uptake rates than standard 2D flat axial devices.Higher uptake rates give excellent low-level sensitivity, even for short sampling periods (down to 15 min).Higher capacity allows you to sample accurately up to 30 days without bias from breakthrough or back diffusion.Versatile, easy-to-use air sampler for a wide range of chemical classes is ideal for environmental monitoring, vapor intrusion, industrial hygiene, and personal air sampling.Solvent and thermal desorption options available.Features water repellant diffusive body and reusable holders.Easy to use—no pump required.Versatile radiello passive diffusive air samplers—now available from Restek—feature a unique 3D radial design that provides several performance advancements compared to standard 2D flat axial air samplers. These samplers are a reliable, cost-effective alternative that offers both high sensitivity for low-level detection in short sampling periods (down to 15 min), as well as higher capacity so accurate results can be obtained over longer (30 day) sampling times. Because the radial design results in a higher rate of uptake and larger capacity, radiello air samplers are a versatile solution that allows labs to sample very efficiently for short durations or sample for longer periods without bias from analyte breakthrough or back diffusion. These air samplers are available for a wide range of chemical classes, so the choice of sampling material can be tailored to specific applications. Ideal for labs supporting environmental monitoring, industrial hygiene, and any other ambient (indoor/outdoor) air testing, radiello air samplers from Restek are recommended when a reliable source of versatile, high-performing, easy-to-use air samplers is required.订货信息：radiello 扩散主体空气采样器货号Product NameType包装RAD120radiello 扩散主体 White diffusive body for general use Samplers and Diffusive Bodies20-pk.RAD1201radiello 扩散主体 Blue diffusive body (same as white, but opaque to light) Samplers and Diffusive Bodies20-pk.RAD1202Yellow diffusive body (for thermal desorption cartridge RAD145)Samplers and Diffusive Bodies20-pk.RAD1203radiello 扩散主体 Permeative body for anesthetic gases/vapors Samplers and Diffusive Bodies20-pk.RAD125radiello 麻醉气体和蒸气采样器 Sterile sampler for anesthetic gases and vapors Samplers and Diffusive Bodies10-pk.RAD130radiello 小柱吸附剂 radiello cart.
