Product Description

WAVE Optimized® Buffers were specifically developed to provide highly reproducible retention times with WAVE® System instrumentation. WAVE Optimized® Buffers have a longer shelf life than buffers prepared from concentrate. They will allow you to generate reproducible data from day to day, week to week, system to system and lab to lab. Not only will they save you time, but reduce problems with water quality and maintenance of purification systems.

WAVE Optimized® Buffers are made in dedicated tanks under scrupulously controlled conditions to ensure clean baselines and long shelf life. For accuracy and consistency, all measurements are performed gravimetrically rather than volumetrically. Most alternative buffers are made in small batches, which typically leads to variations. For example, foreign particles in the volumetric flask can contaminate the buffer, evaporation can affect the concentration of acetonitrile, and fluctuations in temperature can change the volume of the buffer. The possibility of contamination is also higher from non-certified sources of de-ionized water. WAVE Optimized® Buffers are designed and prepared with optimal reagents and conditions to eliminate these problems.

Features

  • Measurements are done gravimetrically to ensure correct concentrations of n-hexylamine hexylammonium acetate (HAA) and acetonitrile
  • Manufactured with the purest chemicals in a metal-free and and clean environment
  • Bottles are conveniently shaped and sized allowing the neck of the WAVE Optimized® Buffer bottles to fit exactly into the WAVE® System cap

Benefits

  • Highly reproducible retention times from batch to batch
  • Clean baseline and long shelf-life
  • Eliminates buffer transfer – just open the bottle and connect it to the WAVE® System
  • Minimizes operator exposure to acetonitrile
  • Decreases evaporation of acetonitrile – a common cause of batch-to-batch variation in laboratory made and other purchased buffers

One of the advantages of WAVE Optimized® Buffers is stability. Because the buffers are manufactured under an inert atmosphere, they are stable during storage and after the bottles are opened. From the first to last drop of WAVE Optimized® Buffer A and B, retention of the heteroduplexes and resolution of the homoduplexes were reproducible for 500 consecutive injections.

Retention times are consistent throughout this series of injections; corresponding peak heights and baseline resolution are unchanged.
