Waters 2695 HPLC System w/ PDA Detector
The Waters 2695 HPLC System integrates solvent and sample
management with consistent system-to-system performance and high reproducibility.
The Waters chromatography system ensures the reliability of results through high
injection precision for precise quantification and exceptional retention time
repeatability for accurate peak identification. The 2695s solvent delivery
system features quaternary blending with a fixed delay volume for consistent
and predictable results, regardless of system back pressure. With pulse-free
solvent delivery through the serial flow path without the use of dampeners and accurate
flow from online solvent degassing and automated solvent compressibility for, the
Waters HPLC system truly features advanced solvent delivery capabilities.
The 2695 HPLC System includes the Waters 2996 HPLC PhotoDiode Array Detector. The 2996 PDA Detector is the most versatile HPLC photodiode array detector available with the highest sensitivity; it operates exclusively with Waters Empower software to provide complete spectral acquisition and results management.
Waters HPLC systems are built for various applications and
routinely used in analytical environments, such as food safety, forensic, research
and development, quality control, and chemistry and pharmaceutical laboratories.
All of our equipment is fully tested to perform at factory
specifications before being shipped.
