UPLC GPC Waters Column Development?
<p><span>Is there any Waters UPLC GPC colulmn being developed that would use ACN or Methanol liquid phase? I have a possible application with UPLC/MS ESI+ for the analysis of Polyetheramines. I am currently using a BEH C18 1.7um 2.1 x 150mm Column with a water & ACN liquid phase gradient, 70C, 0.3 ml/min. I need greater resolution. The MW ranges are 2000 - 5000.</span></p>
