ディテクター（検出器）としては目的とする物質の性質に応じて光学的性質（吸光度、屈折率、蛍光等）、電気化学的性質、質量分析法などを利用する装置がある。

전자를 '고정상', 후자를 '이동상'이라 부르며 크로마토그래피에서는 분석자는 고정상과 이동상의 조합에 의해 분석물의 분리를 제어할 수 있게 됩니다.따라서 분석물, 고정상, 이동상, 세 가지 특성의 이해가 크로마트그래피에서 매우 중요합니다.

Recording and examining facts is essential for interpreting the effects of the HPLC experiment. By finding out the chromatogram, analysts can establish and quantify the components in a mix and evaluate the achievement in the separation.

Gradient optimization: In gradient elution, the mobile stage composition adjustments after some time. An improperly made gradient may lead to bad resolution. Review your gradient profile and alter the gradient slope or solvent ratios to achieve greater separation amongst analytes of interest.

The pump is answerable for delivering the cellular phase at a constant move charge. This makes certain that the cell period is constantly fed to your column.

Increase a identified volume of the antidepressant protriptyline, which serves as an internal conventional, to each serum sample and to each external typical. To eliminate matrix interferents, pass a 0.5-mL aliquot of each and every serum sample or standard by way of a C18 stable-section extraction cartridge. Soon after washing the cartridge to eliminate the interferents, elute the remaining constituents, such as the analyte and The interior common, by washing the cartridge with 0.

, for instance, has two cell section reservoirs which might be employed for an isocratic elution or possibly a gradient elution by drawing solvents from a person or each reservoirs.

The data acquisition system information and procedures the signals with the detector, enabling to the creation of chromatograms and the quantification of compounds.

Acid–base chemistry isn't the only illustration of a secondary equilibrium response. Other illustrations include things like ion-pairing, complexation, along with the interaction of solutes with micelles. We're going to think about the previous of read more those in Chapter twelve.seven after we go over micellar electrokinetic capillary chromatography.

The mobile period’s flow rate is set via the blended speeds of The 2 pumps. By changing the relative speeds of the two pumps, diverse binary cell phases may be geared up.

It truly is essential for laboratory personnel to get a fundamental comprehension of HPLC prior to employing it to analyze compounds precisely and be certain trustworthy outcomes.

특히 컬럼의 선정은 분석의 결과에 영향을 미치기에 신중하게 선택하여야 합니다.
