8. Conclusion

This article deals with the practical aspects of qualifying analytical equipment. It is clear that the tests cited and the acceptance criteria given are examples only, and must be adapted or supplemented as equipment technology evolves. The implementation of relevant tests enables the user to gain a better understanding of the equipment and the factors influencing measurements, and thus to better control the results of analytical methods. Monitoring equipment is an onerous task, but it is the key to improving product quality.
