Twin liquid chromatography is usually a multichannel HPLC method applying two different circulation paths in one process to run two analyses at the same time.

While ECD general performance generally compares towards the sensitivity in FLD, a bonus of electrochemical detection is a immediate measurement of the analyte without making use of complicated, time-consuming derivatization techniques.

Handy for cases when you might want to maximize sample throughput, like examining a sample for pesticides and phenol in only one operate or carrying out replicate analyses concurrently

Thermo Fisher Scientific features numerous types of detectors to protect all HPLC applications. This desk will let you pick which HPLC detector you'll want to look at based upon an analyte’s physiochemical Homes:

Utilizing a PDA detector helps you to measure a constant UV spectrum, causing a multi-wavelength chromatogram. The detector offers not merely a chromatogram that refers to time to the X axis and absorbance over the Y axis, as obtained With all the UV detector, but in addition three-dimensional info getting a wavelength axis about the Z axis.(Fig.5)
