Syringe pumps eliminate peristaltic pump tubing wear and pulsation that can adversely affect both short and long term stability. Sample and diluent delivery is stable over a wide range of (200 fold) of mixing ratios. Stability at low sample flow rates provides the greatest inline dilution factors of any commercial sample preparation system available. Constant preset delivery rates of solution by the S400V provide long term signal stability at all dilution factors.
