WebMobile phase: Methanol and water (16:34). Standard solution: 10 mg/mL of USP Topiramate RS and 0.04 mg/mL of USP topiramate related compound A RS in mobile phase.. Sample solution: 10 mg/mL of Topiramate in mobile phase.. Chromatographic system: Refractive index Detector; Column: L15 packing (4.6 mm × 150 mm; 5-μm); Column temperature 35 … Webin ion chromatography where the mobile phases can have extreme pH values, the reservoirs need to be made of glass or preferably a suitable plastic such as PEEK (polyether-ether-ketone). The advantage of PEEK is that it is also inert to many organic solvents that may need to be used in the mobile phase.

If a peak is completely split in two or forms a shoulder peak, gaps might have developed inside the column. In such cases, rinsing the column will not restore performance. how to tan a deer tail
