The solvent shipping system is made up of a pump, through which solvent (cellular section) is delivered at a managed stream rate. If air gets dissolved inside the cellular stage, it could produce air bubbles that fluctuate the move price.
각각 다른 산업 분야에 대한 자세한 정보 및 다양한 카테고리는 다음 써모 피셔 사이언티픽 학습 센터에서 산업 및 응용 과학 페이지를 확인하세요.
. HPLC separation of a mix of flavonoids with UV/Vis detection at 360 nm and, inside the inset, at 260 nm. The choice of wavelength impacts Every analyte’s signal.
Don't forget, consulting your instrument handbook as well as the company's technical aid may also be worthwhile means when troubleshooting particular issues with all your HPLC system.
The data acquisition system information and analyses the detector alerts, enabling chemicals to get quantified dependent on their own peak regions during the chromatogram.
모든 과학 분야에서 과학자들을 지지하는 기반이 되는 기술로, 장치뿐만 아니라 컬럼이나 그 활용 방법 등도 날마다 업데이트되고 있습니다.
규제 약물(마약, 합성 마약, 대마, 각성제, 향정신성 의약품, 아편양제제 등), 반도핑 관련(금지 물질, 금지 약물, 스테로이드 등), click here 약물 대사물
The stress tends to make the procedure considerably faster in comparison to column chromatography. This enables making use of Considerably more compact particles to the column packing material.
Ghost peaks are extraneous peaks that appear in the chromatogram but You should not correspond to any parts during the sample. These can complicate details Assessment. Below are a few opportunity causes and options:
). Should the detector is actually a website diode array spectrometer, then we also can display the result as A 3-dimensional chromatogram that demonstrates absorbance to be a functionality of wavelength and elution time.
Conversely, a flow rate that may be also lower can cause excessive band broadening. Check your move level configurations and alter them according to the recognized system.
In the event the mobile stage’s pH is sufficiently acidic, the solutes are existing as neutral weak acids which might be more soluble within the stationary phase and acquire for a longer time to elute. Because the weak acid solutes don't have identical p
ノブをインジェクト側に切り替え、サンプルを流路に注入する。マニュアルインジェクターに電気信号を出力する機能が付いていれば、この時にインジェクション信号を検出器またはインテグレーターに送ることが出来る。
, such as, demonstrates an amperometric flow cell. Effluent within the column passes more than the working electrode—held at a constant opportunity relative to the downstream reference electrode—that completely oxidizes or cuts down the analytes.
