What you need to know about the main points of centrifuge maintenance

Regarding the maintenance points of the centrifuge, you need to master the equipment that the centrifuge mainly uses the strong centrifugal force generated by the high-speed rotation of its rotor to quickly settle the particles in the liquid, thereby separating the materials with different sedimentation coefficients and buoyancy densities in the sample.
, plays a pivotal role in biology and other fields
.

Therefore, in order to prolong the service life of the instrument, in addition to mastering the operation process, daily maintenance is also indispensable.
Let's take a look at the maintenance points of the centrifuge
.

One, the one-time rule
.

When the user discovers that the centrifuge system is malfunctioning, certain states can be tentatively changed, one parameter at a time
.

For example, to limit the problem of dedimensionalization of chromatographic peaks, you can change the mobile phase, change the guard column, change the analytical column and so on
.

Technicians say that you don't need to be too nervous when something goes wrong.
In fact, sometimes you just need to make some simple changes and you may be able to solve the problem
.

Second, the second comparison rule
.

If the user has identified the fault before starting the maintenance, or has determined the solution to the fault, he can try the secondary comparison rule
.

For example, if the user finds that the peak value of the internal standard becomes lower during the injection process, he can repeat the injection to see how the repeatability is
.

It is also worth mentioning that the quadratic comparison rule can also be used to examine the situation after the system is changed
.

After changing the flow direction, the standard can be injected twice to check the stability of the retention time and the stability of the chromatographic peak before the formal injection
.

In the gradient elution, if there are redundant peaks, the gradient elution with no load can be performed once.
Using this rule can avoid unnecessary changes and help the user to determine the corrective measures as soon as possible
.

Third, replace the rules
.

If the user thinks that the fault is caused by a certain part, he can replace the suspicious part with a normal part to eliminate the fault
.

"For example, if you suspect that the detector is causing the noise problem, you can replace the detector with a good performance
.

If the centrifuge fault is eliminated, it means that the replaced detector has a problem
.

" The technician said that this rule applies The scale can vary from replacing entire components to replacing integrated blocks on printed circuit boards
.

The above is the relevant introduction about the maintenance points of the centrifuge.
I believe that everyone has a corresponding understanding of this after reading
.

Only by doing a good job in the maintenance of the instrument can the service life of the instrument be extended to a relative extent.
In addition, the editor also reminds everyone that you must not choose the inferior instrument for the small price.
I hope the above content will be helpful to everyone
