Tailing absorption
Web15 Oct 2024 · The EM wave absorption performance of porous HGC absorbers compared with other similar carbon materials. Inspired by chemical-etching method, this work showed a controlled way to selectively tailor the porous GC by the chemical etching methods with the employment of H 2 O 2 as the covalence-tailoring reagent. WebIn daily work with HPLC systems, we meet a variety of problems in chromatograms, like baselines, peaks, retention time, etc. Here we analyze some problems about the peaks. 1. Small Peak. 2. Negative Peak. 3. Tailing Peak & Leading Peak. 4.
