      Validex™ Count Precision Size Standards

      北京华泰昕生物公司代理Thermo品牌Validex产品,该系列产品是应用于饮用水工业领域内的微粒计数仪的性能验证。

      1. 详细信息

      微粒计数在饮用水工业领域内已经成为优化饮用水质量的一种必不可少的方法。应用于饮用水工业领域内的大多数微粒计数仪的运行原理是基于单微粒的光线遮蔽作用。

      Validex 计数质控成品为悬浮于超纯水内的NIST 溯源的聚合物微粒,其微粒浓度是液体微粒计数仪性能验证的理想浓度。

      此类产品的悬浮液已经被优化,以促进微粒的分散。

      每个包装瓶内含 500 mL悬浮液,标称微粒浓度为1000微粒/ mL。每个包转瓶内同时包括一个搅拌棒,来辅助微粒分散。


      Validate the performance of liquid particle counters with Thermo Scientific™ Validex™ Count Precision Size Standards. Excellent for instrument calibration and verification in the drinking water industry and for low level liquid particle counting and calibration, standards contain NIST™-traceable polymer particles packaged in ultrapure water at concentrations ideal for use in validating the performance of liquid particle counters.

      Particle counting in the drinking water industry has rapidly become an indispensable technology for optimizing water quality. The majority of particle counters used in the drinking water industry operate on the principle of single particle light obscuration.
