Description


The Waters Alliance Chromatography systems are designed for a wide variety of applications.  This reliable tool is a common work-horse in most analytical and contract labs.  Built to meet labs rigorous requirements or routine analysis, this robust instrument is easily found in Pharmaceutical, Food Safety, R&D, Chemistry, Environmental or Quality Control labs.  The Waters 2695 features a large, easy-to-use LCD interface.  Scientists can take advantage of the quick autostart and optimize their methods with a simple push of a button.  Manage up to 120 industry standard vials with the built in autosampler.Simplify how you collect data, built-in compliance and validation features.  The Empower software is capable of automating method development, archiving methods and customizing data reports.  Other features include audit trails with ConnectionsAQT (GxP & 21 CFR Part 11 requirements).

Solvent Management     

  • Number of Solvents -  1 to 4
  • Solvent conditioning - Vacuum degas, two operating modes, four chambers, < 500µl internal volume per chamber 0.000 to 10.000 mL/min (0.050 to 5.00 mL/min typical) in 0.001 mL/min increments
  • Compressibility compensation - Automatic and continous
  • System delay volume -  < 650 µL, independent of backpressure at 1mL/min
  • Plunger seal wash - Integral, active, programmable
  • Gradient profiles - 11 gradient curves including linear, step (2), concave (4), and convex (4) 
  • Dry prime/wet prime - Automatic front panel control, SystemPrep function for automatic solvent(s) purge
  • Flow ramping -     Time (0.01 to 30.00 min in 0.01 min increments) to reach maximum flow rates
  • Maximum operating pressure - 5000 psi (345 bar) (0.010 to 3.000 mL/min) programmable upper and lower limits
  • Composition range -  0.0% to 100.0%, in 0.1% increments
  • Composition accuracy -     ±0.5% absolute, independent of backpressure (proportioning valve pair test, [degassed methanol: methanol/propylparaben, 2.0mL/min, 254nm])
  • Composition precision - ≤0.15% RSD or ≤0.02 min SD, whichever is greater, based on retention time (degassed methanol: water 60:40 dial-a-mix, 1.00mL/min, six replicates, phenone mix, 254nm)
  • Flow precision - ≤0.075% RSD or ≤0.02 min SD, six replicates, based on retention time or volumetric measures (0.200 to 5.000 mL/min), isocratic premix
  • Flow rate range - 0.000 to 10.000 mL/min (0.050 to 5.000 mL/min typical) in 0.001mL/min increments
  • Flow accuracy - ±1% or 10µl/min whichever is greater, 0.200 to 5.000 mL/min (degassed methanol, at 600 psi backpressure)
Sample Management     
  • Number of sample vials - 120 vials, configured in five carousels of 24 vials each
  • Number of sample injections -1 to 99 injections per sample vial
  • Sample delivery precision - Typically <0.5% RSD, 5 to 80µl (degassed methanol: water 60:40 dial-a-mix, 1mL/min, six replicates, phenone mix, 254 nm)

  • Injection volume range - 0.1 to 100.0µL, standard; 0.1 to 2000.0µL, with optional sample loop
  • Injection linearity - > 0.999 coefficient of deviation (1.000 to 100.000µL)
  • Minimm sample required - 10µL, using low volume inserts
  • Sample temperature control (optional)     4 to 40°C, programmable in 1°C increments
  • Column heater (optional) - 20 to 65°C, in 1°C increments (5°C above ambient)
