Gc analysis time too long
WebSep 5, 2024 · The length is related to the overall efficiency of the column and to overall analysis time. A longer column will increase the peak efficiency and the quality of the separation, but it will also increase analysis time. One of the classical trade-offs in gas chromatography (GC) separations lies between speed of analysis and peak resolution. Choosing the right stationary phase is the first step toward optimizing your GC separation. It is the most important decision you will make because the separation factor (α) has the greatest impact on resolution, … See more Once you have chosen the stationary phase, you need to determine which column film thickness and inner diameter combination will give the retention factor (k) needed for optimal resolution and speed. Retention … See more An analyst observed that no peaks appeared during a GC-FID analysis. The flowchart below shows a logical progression of steps … See more
