The differences between acetonitrile and methanol in reversed-phase chromatography are significant and can impact the efficiency, cost, and quality of your analysis. First, acetonitrile is generally more expensive than methanol, which may be a consideration for labs with tight budgets. Additionally, acetonitrile has a higher absorbance at UV wavelengths, particularly around 210 nm, making it less suitable for certain low-concentration analyses where baseline stability is critical.
In terms of pressure, acetonitrile tends to produce lower backpressure in HPLC systems compared to methanol, which can help extend column life and reduce pump wear. Regarding elution strength, acetonitrile is a stronger eluent than methanol, meaning it can resolve compounds more effectively, especially for polar or moderately polar substances.
Separation selectivity also differs between the two solvents. Acetonitrile often provides better resolution for complex mixtures, while methanol may be more effective for certain specific analytes. Peak shape is another factor—acetonitrile typically results in sharper, more symmetrical peaks, contributing to better chromatographic performance.
