Hello!
Does anyone have suggestions for which brands and lots of Acetonitrile
are optimal for minimal chemical noise in MS? We are using a LCQ Deca
for nanocapillary spray work and have been fighting a battle with "marching
background" at concentrations of Acetonitrile between 15-35%+. Is this
increase in noise normal, or are there options in solvent choice to
minimize it?
Thank you for your input!
