Most labs and testing facilities today will require a High-Performance Liquid Chromatography or HPLC system. These complex systems are used to separate, identify and to quantify each particular component within a sample.
The basic operation of an HPLC is to pump the sample through a column. This column is filled with a specific type of absorbent material that causes a different ability to absorb base on the individual compounds in the sample. As these different components react, there is a variable flow rate, which can be used to detect the individual compounds.
Similar to other liquid chromatography systems, the HPLC adds the pump, which provides constant pressure and can speed up the testing process while maintaining high levels of accuracy.
These systems can be very costly, which makes it a challenge for smaller labs or even established labs to replace current equipment or to add new testing options. A simple solution to this problem is to buy a used HPLC.
One of the first factors to note when choosing a used HPLC is the ability to compare a variety of models and manufacturers in the same location. By selecting an established, reputable, specialized company offering these systems and other used analytical and laboratory equipment, you can compare to manufacturers to find the system that is ideally suited to the requirements of the lab.
It is also important to consider that with the lower pricing, it may be possible to upgrade to a superior capacity model of used HPLC or one with added features. This can assist a lab in having a greater testing capacity or completing specific types of tests that may not have been possible with older equipment.
For labs that are constantly expanding their testing capacities, choosing a module option of HPLC may be an important decision. This will allow for the addition of features and functions over time without the need to replace the base components.
