Certain compounds cannot be properly analyzed using the UV detection light since they are either incapable of absorbing the light or that form of analysis has been restricted. In this case, such compounds are analyzed by the evaporative light scattering detector instead. There are various compounds that fall into this category and include antibiotics, lipids, sugars, antivirals, alcohol, phospholipids among others. This tool has been said to use the same principle as the refractive index devices. For it to function efficiently, the ELS Detector with a form of column chromatography known as high-performance liquid chromatography (HPLC).
This device may work in a way that resembles that of refractive index tool but the main principle of employing HPLC makes them have a slight difference. It employs a series of breakdowns and reactions on the analyte from the first to the last stage. In the last or analysis zone, the device produces a light beam that gives the different regions of the analyte where conclusions are drawn from. This occurs after separation of the analyte to solvent and solute.
This device is designed to perform activities like the discovery of drugs, development of natural products, and chemistry of combinations, as well as beverage and food chemistry. This is because it allows for viewing of elements constituting a compound from semi-volatile up to the complex ones. It is efficient when separation of elements in a compound is needed.
A typical device will use LED lighting and signals as well as produce low noises and give a definite analysis of the analyzed materials. It should be able to have high sensitivity and traceable analytical characteristics. However, these devices come in different models. For instance, there is a universal detector. This device deals with the analysis of non-volatile as well as semi-volatile analytes.
Mostly, compounds with this volatility characteristics become hard to analyze when exposed to wrong temperatures. Most of them will give correct information when subjected to around to temperature of around 40 degrees. Exposure to high temperatures causes decomposition of these elements interfering with the process. Many devices may not have auto-regulation of temperatures a factor that interferes analysis.
Other than detecting compounds missed by other detectors, a good model should have good gas flow control so as to avoid the wasting of gas used after the process is done. There should be a gas shut-off that is automatic in order to aid in gas conservation. Fouling should also be minimized. These mechanisms have to be set in place so as to minimize noise production and evade frequent repairs.
It should also have a single-mode method of operation. When a device has low temperature operating mechanism, the analysis conducted will not require different conditions as this fits almost all analytes. It should also be easy to operate. Most effective devices will give specific color codes for certain analytes that contain similar properties even if they do not have the same spectroscopic characteristics. This helps in classification and grouping.
It is more preferred to refractive index devices because the latter has lower sensitivity in comparison to the former. Also, this device is capable to detect all categories of compounds some of which can be missed when tested by other detectors.
