Water suitable for HPLC is commonly used as a solvent for isocratic elution in both cation and anion chromatography. Additionally, it is used as a component to prepare standard stock solutions, and for evaporation under a nitrogen stream in a water bath to concentrate the sample before LC-MS-MS analysis. [1] [2]

HPLC用水可以通过专门的纯水机或超纯水机来得到。 按用途，超纯水可以分为二个大类，仪器专用和生物培养专用，仪器用的超纯水高配置的除了交换柱外，还有紫外灯和0.22um过滤头二个可配附件。

Agilent InfinityLab HPLC Water is an HPLC gradient grade water that is 0.2 µm prefiltered and manufactured at the lowest levels of impurities. This consistent lot-to-lot quality of Agilent HPLC water helps to avoid unwanted troubleshooting and …

Among the different water contaminants that may affect the quality of water used for sample dilution, standard solutions or mobile phase preparation, organics are probably the most important ones, as the results below demonstrate.

In HPLC analysis, water is essential for use in preparing mobile phases and samples. If impurities are present in a mobile phase, however, they can increase background signals that can increase baseline noise, drift, or cause other phenomena, such as negative peaks or unknown peaks during gradient elution.

Water of the special quality required for HPLC can be purchased from various manufacturers or be produced directly on site for use on demand by employing a water purification system, such as the arium® pro VF system.
