Everything To Understand About The 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.

The system undergoes different stages, each follow specific procedures. Again, the whole working environment should be free from contaminants. Specialists should also equip themselves with their personal protective equipment. Following that, its important that separating the different components must be efficiently done prior on moving to the succeeding stages.

In a typical SPE procedure, this could involve five fundamental steps. Every step needs close and careful attention to details to ensure that nothing is overlooked. Often, the samples mostly undergo various processes and containers. So, if things get out of control, there is a greater risk that impurities fill containers, causing inaccurate and poor result that you do not want to happen.

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 feasible technique is regarded as ion exchange that uses the interaction of electrostatic to provide the variables and figures. Both stationary phase and samples must be at pH level where they are totally charged. Otherwise, this might fail to succeed and work well. Ion exchange should be completely observed to achieve the best and expected outcome.

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.

Explained above are some procedures that show how complex and daunting the system is, in general. But you have to remember that safety is the ultimate priority. It should never be taken lightly. More importantly, cooperate with teammates to speed operations and attain efficiency and precision of result.
