HPLC Optical Rotation Detector (ORD)  

Specific for the optical isomer measurement. The column can separate R- and L- type optical isomers, but the general detectors (e.g., UV) cannot distinguish which is R nor L. OR detector provides this information.
In chiral chromatography, the technology of detecting chiral molecules using optical devices has lagged behind until now. The stability and sensitivity of this type of instrument is an important issue in chiral chromatography. However, with the availability of the single wavelength LED, increased sensitivity and increased economics with simplified instrument design was possible. In addition, a newly designed glass coated steel flow cell has produced a superior, third generation optical rotation detector. Aided with the Faraday compensation technique, this instrument gives high o

The actual separation of each component in the sample is carried inside a column; however this separation needs to be "collected" for us to be able to see it. The detectors are used for this purpose. The separated coponents are monitored and expressed electronically. There is no universal detector that can monitor all compounds and there are many detectors used for LC analysis. Some are listed below.

1100 HPLC  

Introduced in 1995, Agilent's 1100 series HPLC system is considered the world's most popular HPLC. They are incredibly robust machines that can last a long time. Finding a used Agilent 1100 on LabX is easy and maintenance for older machines consists of changing seals, filter solvents, lamps, and the odd part in the vacuum degasser. Parts from the Agilent 1050 are often shared with the Agilent 1100 which make it easy to maintain.

Chromatography terms / analyte / Analytical chromatography / bonded phase / chromatogram /...  

The analyte is the substance to be separated during chromatography. It is also normally what is needed from the mixture.
Analytical chromatography is used to determine the existence and possibly also the concentration of analyte(s) in asample.
A bonded phase is a stationary phase that is covalently bonded to the support particles or to the inside wall of the column tubing.
A chromatogram is the visual output of the chromatograph. In the case of an optimal separation, different peaks or patterns on the chromatogram correspond to different components of the separated mixture.
 Plotted on the x-axis is the retention time and plotted on the y-axis a signal (for example obtained by a spectrophotometer, mass spectrometer or a variety of other detectors) corresponding to the response creat
