WebHPLC의 작동 방식. HPLC 기기는 일반적으로 펌프, 자동시료주입기, 컬럼 및 검출기의 네 가지 주요 하드웨어로 구성됩니다. 추가적인 구성 요소인 용매, CDS 패키지, 연결 캐필러리 및 … WebBuffering is commonly needed when analyzing ionizable analytes with reversed phase LC. For compounds like these, the pH of the mobile phase determines whether they exist in the ionized or non-ionized form. This does make a difference because the ionized species always elute from the column earlier for reversed phase LC.

WebAir yang digunakan untuk analisis HPLC harus memiliki kemurnian yang tinggi. Air ultrapure yang sesuai dengan kemurnian tertinggi yang ditentukan dalam Tipe 1 oleh standar ASTM biasanya digunakan untuk aplikasi HPLC. Air tersebut membutuhkan deionisasi dan filtrasi dengan filter membran 0,2μ. Web8 apr. 2024 · Buffer selection mainly depends on the desired pH of the mobile phase and which in turn depends upon the analyte’s pKa value. Thus, ideally you should choose a buffer which has it’s pKa value as close as possible to the required mobile phase pH value.
