Centrifuge maintenance rules:

(1) One rule

When the system malfunctions, you can tentatively change certain states, one parameter at a time. By making some simple changes, perhaps the problem can be solved.

(2) Secondary comparison rule

Before starting the manual maintenance, the fault location has been identified or a solution to the problem has been determined. In other words, the solution has already been found before taking action. For example, if it is found during the injection process that the peak value of the internal standard has decreased, the injection can be repeated to check the repeatability. If it is an accidental decrease, it may be due to bubbles entering the quantitative tube. This rule can be used to examine the situation after system changes. After changing the flow, two standard samples can be injected before formal injection to check the stability of retention time and chromatographic peaks. If there are excess peaks in the gradient elution, it is possible to empty the gradient elution once (is there really a problem?). Using this rule can avoid unnecessary changes and determine corrective measures as soon as possible.

(3) Replace the rules

Replacing suspicious components with good ones is a good way to identify faults. If you suspect that the detector is causing noise, replace it with a high-performance rotorless vulcanizing analyzer detector. If the fault is eliminated, it means that there is a problem with the replaced detector. The scale of application of this rule varies, ranging from replacing entire components to replacing integrated blocks on printed circuit boards.

(4) Change back rules

This rule, when applied together with the replacement rule, did not improve the situation after replacing the suspicious component of the solution flow rate tester with a good component, and the original component should be replaced. This approach reduces maintenance costs and prevents the accumulation of used components in the rotorless vulcanizing apparatus. This rule only applies to a single fault.

The principle of exchange does not apply to the following situations:

The new component was damaged when removed (such as the pump sealing gasket);

Low component prices (such as column lining filter);

Reinstalling the original components carries the risk of damage;

Regularly replaced components.
