HPLC Refractive-Index (RI) Detector  

RI detector measures change in reflex index. A glass cell is divided into two chambers (cells). The effluent from LC column flow through the "sample cell", while other cell called "reference cell" is filled with only mobile phase. When the effluent going through the sample cell does not contain any analyte, the solvent inside both cells are the same (Figure 1A). When a beam is irradiate on the cells, the observed beam will be straight in this case. However, in a case the effluent contains any components other than mobile phase; bending of the incident beam occurs due to the reflex index difference between the two solvents (Figure 1B). By measuring this change, the presence of components can be observed.

RI detector has lower sensitivity compared to UV detector, and that's the main reason

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.

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.

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

What Is Evaporative light scattering detector (ELSD)?  

An evaporative light scattering detector (ELSD) is a detector used in conjunction with high-performance liquid chromatography (HPLC). It is commonly used for analysis of compounds that do not absorb UV radiation and therefore cannot be detected by UV detectors, such as sugars, antivirals, antibiotics, lipids, phospholipids, terpenoids, and alcohols.ELSDs fall under the category of general-purpose detectors, similar to refractive index detectors (RI)./wikipedia

Shimadzu Evaporative Light Scattering LC Detector LTII (ELSD-LTII)  

In the history of high-performance liquid chromatographs, which dates to the early 1960s, refractive index detectors (RI detectors) have often been used as general-purpose detectors. RI detectors enable the detection of components that do not possess UV absorbance and give a proportional relationship between the heights of detected peaks and the quantities of detected components. So, in comparison with absorbance detectors (UV detectors), they offer advantages such as the ability to ascertain unknown component quantities and obtain molecular weight distributions for macromolecules. On the other hand, they also have various disadvantages. For example, they cannot be used for gradient analysis, the baselines they produce are susceptible to the influence of fluctuations in the ambie
