LC-MS Solvents from Agilent
All pictures shown are for illustration purpose only. Actual product may vary.
Agilent InfinityLab LC-MS grade solvents have been developed for optimum performance with Agilent LC instruments and applications.
All solvents are manufactured to a high purity level, and are tested and specified for MS applications. The lowest levels of trace metal impurities and low acidity and alkalinity properties help achieve excellent detection limits for mass spectrometry, extend column lifetimes due to reduced contaminants, and minimise ghost peaks in gradient runs.
To protect your system from contaminants and clogging, LC-MS solvents are pre-filtered through a 0.2 µm filter. There is no need to filter separately, unlike lower quality chromatography solvents – the solvents are ready to use. Benefits include reduced troubleshooting and instrument downtime caused by impure solvents.
Agilent LC-MS solvents are easy to use, and offer excellent lot-to-lot reproducibility, ensuring consistent results. Batch specific certificates of analysis are also available to meet GLP specific requirements.
Agilent offers LC-MS grade acetonitrile, methanol and water solvents, which are widely used in reversed phase HPLC applications.
