What To Bear In Mind Regarding A Solid Phase Extraction System

By Helen Robinson


Most analytical laboratories make use of techniques which can analyze samples. One such rapid yet easy to perform and automated technique is known to as solid phase extraction system. Primarily used for sampling preparations, it has been a handy tool for determining factors from a finished matrix. However, the overall process itself entails lengthy and complicated steps.

Based on the methods nature, its pivotal that only the reliable and genuine scientists will handle the activities. Working on a good analytical lab is not a simple thing. Mixing wrong substances and using poor techniques inevitably lead to costly failure and chemical mishaps. To begin, labeling the samples is the major point and keeping the entire area neat and clean should be well observed. Here are some top pointers to bear in everyone mind all the time.

It follows different stages each has its associated process. Needless to say, the working area should be free from danger and harmful entities. Specialists must likewise need safety gears and device. Following such important matter, its relatively vital that separating the components have to be well managed before dealing with succeeding stages and phases.

In a normal SPE process, this might involve 5 basic steps. Every step requires careful and close attention to details to make sure that nothing is missed out. Oftentimes, the samples undergo different containers and process. So, when things get awry, there is a huge risk that impurities might fill the containers, leading to poor and inaccurate result.

Another practical operation is known as reversed phase. In the SPE, this thing basically separates subjects based on polarity. Since this could be quite delicate, observing techniques and reactions ultimately matter. Any unwanted and undesired changes, whether inadvertent or deliberate, could disrupt interactions and could cause an adverse and unwanted effect along the way.

SPE disks and cartridges are highly available which can make the process easier and could help in separating properties according to their chemical properties. But fully understanding the difference of methods and used techniques is the top priority. Although they differ, they might have some similarity which creates certain reactions and consequences.

Another applied technique in the analytical lab industry is known as ion exchange which mostly uses the electrostatic interactions. Both samples and the stationary phases need to be at a pH where both are completely charged. Otherwise, this method might not fully work. Ion exchange must be thoroughly observed to attain the ideal result.

Cation and anion exchanges are two procedures, though works differently, presents the reactions which most experts are looking for. Of course, both the guidelines and implemented steps must be followed. It is one basic factor to take into account to arrive with smart outcome afterward.

The above mentioned process explains the complexity present that gives a solid reason to take them seriously. Should you decide to work on such type of activity, safety is paramount. It is simply one thing that should not be underestimated at all times. Above all, follow cooperation with your teammates to speed operation and achieve the precision and effectiveness of outcome.
