Tandem liquid chromatography methods use a second pump and clever column switching To maximise utilization in the detector by minimizing downtime connected to column reconditioning.
Chromophore: A chromophore is a part of the compound (its structural moiety) that absorbs UV or visible light-weight.

Learn more about our HPLC detectors, and take a look at our HPLC detector collection information to search out the correct detector to suit your needs.
These detectors are suitable with many analytes effective at forming gasoline-phase ions, from compact inorganic salts to substantial macromolecules like proteins.
Reduced-stream methods are perfect for superior-sensitivity measurements of molecules in complicated biological matrices wherever analyte concentrations can span a number of orders of magnitude.
Though ECD performance generally compares towards the sensitivity in FLD, a bonus of electrochemical detection is a direct measurement of the analyte without making use of elaborate, time-consuming derivatization processes.

Chromatogram generation — Translation on the detected analyte sign by the CDS into a chromatogram of analyte signal compared to time.
Sign depth should really correlate with the amount – possibly mass or focus – of your detected sample within the given time stage, letting the quantification and identification on the divided analytes inside of a time-dependent fashion.

Thermo Fisher Scientific delivers numerous types of detectors to protect all HPLC applications. This desk will help you select which HPLC detector it is best to take into consideration depending on an analyte’s physiochemical Attributes:
The size in the cost depends upon the particle dimension, so a larger mass yields A much bigger detector hplc particle with extra charge. This huge particle dimensions brings about increased sign reaction.
