Evaporative light scattering detectors are devices that are used in chromatography to detect and identify compounds and other substances. Chromatography is a field of chemistry where compounds and substances are analyzed and detected. It is used in medicine to determine the presence of infections or harmful substances in the blood and other body samples. It can also be used to determine whether an individual is under the influence of drugs for example, athletes who use performance enhancers. It can also be used by morticians and detectives to determine why an individual died. ELSD is a form of chromatography that can be quite effective in certain cases. Unlike chemical chromatography, ELSD uses the optical properties of a substance to detect it as opposed to its chemical properties. ELSD is useful if the substance being detected is in very small quantities or if it is hard to detect using other methods. ELSD is also far more accurate and precise than chemical chromatography especially of the substance being analyzed is hard to distinguish from other substances present in the sample. ELSD machines are quite complex and also prone to damage if handled without care. Due to their complexity, many parts of ELSD machines can malfunction and for most people, it is hard to determine which ones they are. It is also risky to try fixing the machine yourself as you could spoil it even more. Besides, they might lose their sensitivity over time and need to be recalibrated or replaced. These are all possibly complex and expensive operations that require the assistance of an expert. If you need ELSD machines or the one you own is malfunctioning, you can hire an ELSD company to fix it for you. The article below discusses some factors to consider when choosing an ELSD company
One factor to consider is the licensing and qualifications of the company. ELSD machines are complex and need to be installed and maintained by experts. Badly installed or maintained ELSD machines will often be unable to detect substances with accuracy. Some ELSD machines require the users to look through a lens into the sample being analyzed. If the lens is configured wrongly, it could hurt the eyes of the observer. Licensed companies have experts who can install a broad range of ELSD equipment and make repairs wherever necessary.
Another thing to consider is the experience of the company. ELSD installation and maintenance is a predominantly practical field therefore, the best way to become more competent is through experience. Older companies are usually far more competent than newly formed ones and can address a broader range of issues. This is because they have had more real-world exposure to many problems with regard to ELSD repairs and installation.
Lastly, consider the cost of hiring the company. No company will ever do ELSD work for free but you can find affordable ones. ELSD services are often very expensive so it makes sense to spend your money with caution. Only pay for the services you need and nothing more.
