Filtration for analytics
Whether pursuing analytical goals in life science, pharmaceutical methods, research and development, quality control, or environmental applications, your results need to be reliable and reproducible. You also need to protect your columns and instruments from particulates.
Protecting instruments and columns
Effective filtration of analytical samples and mobile phase solutions reduces instrument downtime, maintenance, and associated costs. It also protects columns and results. Injection of contaminated particulate-laden samples will impact column integrity, causing loss of resolution, poor peak shape, split peaks, and high back pressure.
Protecting your results
Filtration helps ensure instrument and column integrity for more reliable and reproducible results. But a filtration device shouldn’t interfere with your analytes. Our HPLC and IC certified sample prep filtration devices have been designed, manufactured, and tested to ensure low levels of extractables.
