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 happen to be Utilized in HPLC. Measuring a improve during the cellular section’s refractive index is analogous to checking the cell period’s thermal conductivity in gasoline chromatography. A refractive index detector is sort of common, responding to Practically all compounds, but has a comparatively weak detection Restrict of 0.
The world of the peak is routinely detected by the pc. The computer also detect the retention time of that specific component.
- 분석결과는 재현성이 우수하며, 특히 오토샘플러 등을 사용함으로써 보다 높은 재현성을 확보할 수 있어 생산성을 한층 더 향상시킬 수 있습니다.

. HPLC–MS/MS chromatogram for check here your dedication of riboflavin in urine. An First father or mother ion having an m/z ratio of 377 enters a 2nd mass spectrometer where by it undergoes further 20 ionization; the fragment ion using an m/z ratio of 243 gives the sign.
加温することが多かったため「オーブン、ヒーター」と称されるが、現在では周辺気温より低温にするための冷却機能が付いている装置も多い。また、周辺気温付近で使用する場合にも冷却機能は一定の効果がある。
Increase or decrease the ionization condition of analytes, affecting their affinity for that stationary section.
. HPLC chromatogram with the resolve of riboflavin in urine working with fluorescence detection with exci-tation in a wavelength of 340 nm and detection at 450 nm. The height similar to riboflavin is marked which has a crimson asterisk (*).
In a gasoline chromatograph the stress from the compressed fuel cylinder is sufficient to thrust the cellular phase from the column. Pushing a liquid cellular section through a column, having said that, normally takes an excellent offer extra energy, making pressures in excess of many hundred atmospheres.
There are many choices for checking the chromatogram website when using a mass spectrometer as being the detector. The most common strategy is usually to consistently scan the entire mass spectrum and report the total signal for all ions reaching the detector during Every single scan. This full ion scan provides universal detection for all analytes. As viewed in Figure 12.5.14
. Illustration of an average high-performance liquid chromatograph with insets demonstrating the pumps that move the mobile stage from the system and the plumbing used to inject the sample in the cell section.
