Sigma-Aldrich can help you to save Acetonitrile by changing to Ascentis Express HPLC columns

• Double efficiency compared to 3µm columns enables a transfer to short columns and ACN savings
  
  
• Can be used with high flow rates for faster chromatography - and further ACN savings

Ascentis Express columns provide a breakthrough in HPLC technology and column performance. This technology provides much lower dispersion and a much tighter particle size distribution, increasing column efficiency very significantly.
