Web28 Mar 2024 · A pH greater than 3.2 (using 10 mM NH 4 COOH) resulted in CMB peak tailing and longer running times. A higher percentage of ACN (greater than 45%) resulted in overlap of the CMB and PMT peaks, while a lower percentage led to longer running times. Web2 days ago · The peak area precision typically corresponds to approximately 1–2% relative standard deviation (RSD), which is not as good as HPLC. However, this difference between HPLC and CE is often irrelevant, if biotechnical products are investigated, or if substantial sample pre-treatment is required.
