To circumvent the loss of stationary phase, which shortens the column’s life time, it truly is certain covalently on the silica particles. Bonded stationary phases
Bubbling an inert gasoline with the cellular phase releases volatile dissolved gases. This method is called sparging.
The content of our Web page is usually accessible in English and partly in other languages. Pick your most popular language and We are going to demonstrate the written content in that language, if out there.
By pursuing these guidelines and systematically addressing potential causes, you can properly troubleshoot prevalent HPLC problems and make certain your analyses are exact and trustworthy.
イオン交換クロマトグラフィーでは、無機イオンや高極性分子を電荷を利用して分離する。陽イオンタイプと陰イオンタイプの両方がある。イオン交換樹脂を利用する。
. The working pump as well as equilibrating pump Every single Have a very piston whose back and forth movement maintains a continuing flow fee of around a number of mL/min and offers the high output force necessary to force the cellular phase throughout the chromatographic column.
규제 약물(마약, 합성 마약, 대마, 각성제, 향정신성 의약품, 아편양제제 등), 반도핑 관련(금지 물질, 금지 약물, 스테로이드 등), 약물 대사물
Establishing an optimized HPLC system includes strategically adjusting a variety of parameters to achieve the absolute best separation for your distinct analytes. click here Essential parameters for optimization involve:
Ghost peaks are extraneous peaks that surface during the chromatogram but Do not correspond to any components in the sample. These can complicate data Investigation. Here are some prospective triggers and options:
A pump forces a solvent through a column beneath high pressures of up to 400 atmospheres. The column packing substance or adsorbent or stationary stage is typically a granular content of solid particles including silica or polymers.
The column is the separation chamber exactly where the magic of HPLC occurs. It properties the stationary period, a packed bed of microscopic particles.
The realm under Just about every peak is proportional to the amount of the corresponding analyte. The information acquisition system permits the Investigation of peak retention periods, peak places, as well as calculation of analyte concentrations.
Analyte solubility: The picked out solvent should correctly dissolve the target analytes. Experiment with distinctive solvents to locate the best website one particular for your personal particular sample.
While using the Assessment method comprehended, let's deal with widespread difficulties which will occur and the way to troubleshoot them.
