Linearity - HPLC

NettetIn simple terms, linearity tells us how well the instrument measurement corresponds to reality. In this case we want a linearity as close to 1.0 as possible. A linearity of 1.0 means that if the real position of the material is 1.0 mm to the right, then the measurement instrument reports a displacement of 1.0 mm to the right. NettetWhen dealing with MS data, especially HPLC-MS, we almost always work in log space. Normal space linearity is great if you're dealing with Beer's law; otherwise, it's kind of … Nettet25. sep. 2012 · 5.4.2 Prepare five test solutions of the analyte at 80%, 90%, 100%, 110%, and 120% of the method concentration using serial dilutions from a stock solution.
