Abstract
Quality Assurance (QA) describes all planned and systematic activities that are implemented in a quality program. It is the sum of all measures to ensure quality. Quality Control (QC) deals with the techniques and activities to monitor a process yielding quality as well as to remove causes of unsatisfying results. Both, QA and QC are closely related, QA being rather the overall frame to define and obtain good quality and QC being the continuous approach to maintain quality goals from QA.
In general, QA matters ask for rather formal programs such as the life cycle model for instrument monitoring or method validation for analytical performance. The methods and techniques to be used will be addressed and discussed. The focus will be directed to activities that are beneficial to ensure good overall quality in gas chromatography without increasing additional workload in QC activities: a test set up in a smart way will probably tell more about quality of the current chromatography than a sequence of standard tests.
Emphasis is also placed on soft skills. A framework of QA and a set of QC activities will lead to good quality, but do not grant for any departure from normal. Expertise, training, awareness, continuing education and communication are paramount capabilities in maintaining quality.
