显示摘要
Water plays a critical role in many analytical methods—particularly in the preparation of samples, standards, blanks, and eluents. It is crucial that water used for these applications does not introduce any impurities that could interfere with analytical results. As modern analytical instruments become capable of detecting ever increasingly low concentrations of analytes, ensuring the lowest level of background interference has become even more important—and more difficult. To meet this challenge, laboratory water purification systems have evolved accordingly. Current systems such as the Milli-Q Integral use a sophisticated combination of purification technologies to reduce ions, organics and other potentially background-causing contaminants to extremely low levels (i.e., 18.2 MΩ.cm resistivity and <5 µg/mL of TOC). 全文本文章 |
