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。
Many other detectors are actually used in HPLC. Measuring a improve within the cell section’s refractive index is analogous to checking the cell section’s thermal conductivity in fuel chromatography. A refractive index detector is almost common, responding to Virtually all compounds, but has a relatively poor detection Restrict of 0.
, for instance, has two cell phase reservoirs which are employed for an isocratic elution or maybe a gradient elution by drawing solvents from a single or both of those reservoirs.
- 분석결과는 재현성이 우수하며, 특히 오토샘플러 등을 사용함으로써 보다 높은 재현성을 확보할 수 있어 생산성을 한층 더 향상시킬 수 있습니다.
A number of other detectors have already been used in HPLC. Measuring a change during the cell section’s refractive index is analogous to checking the cell section’s thermal conductivity in fuel chromatography. A refractive index detector is sort of universal, responding to Practically all compounds, but has a comparatively inadequate detection Restrict of 0.

, as an example, has two mobile phase reservoirs that happen to be employed for an isocratic elution or read more maybe a gradient elution by drawing solvents from 1 or equally reservoirs.
one–one μg of injected analyte. A further limitation of the refractive index detector is the fact it can't be useful for a gradient elution unless the cell section factors have similar refractive indexes.
Ion-exchange chromatography is predicated about the separation of substances centered on their own cost. The stationary period consists of billed groups that catch the attention of and keep oppositely billed ions in the sample.
In liquid–liquid chromatography the stationary period is often a liquid movie coated on the packing content, generally three–10 μm porous silica particles. Since the stationary section could be partly soluble while in the mobile phase, it may well elute, or bleed within the column eventually.
The area beneath each peak is proportional to the quantity of the corresponding analyte. The info acquisition get more info system permits the analysis of peak retention moments, peak spots, and also the calculation of analyte concentrations.
are produced by reacting the silica particles with an organochlorosilane of the general type Si(CH3)2RCl, the place R is an alkyl or substituted alkyl team.
The separation of the individual parts in the mixture usually takes spot during the stationary phase inside the column. In lieu of the glass column, it is prepared in stainless steel.
