In the laboratory quality is synonymous with accuracy. For a laboratory accuracy of results is of paramount importance as a failure to achieve accuracy in a set of results could lead to damaging financial loss in a marketing environment or even result in a miscarriage of justice if quality control is inadequate within a forensic lab. Quality control within a lab must therefore control all factors in the analytical system that may influence the analytical results.

Instruments used in the determination of results along with auxiliary equipment and the materials involved in the analytical operations are all extremely important factors within an analytical system, therefore the functioning ca

pability of these factors must be optimised. Lab instruments such as A.A spectrometers and gas chromatographs must be maintained in order to produce sufficiently accurate, reproducible results. Lab personnel experienced in the operation of the instrument usually carry out general maintenance, such as the replacement of consumable parts and cleaning. Instrument specialists are employed for repairs lab personnel are unable to fix. It is necessary, for a quality system, that all personnel, whether in-house or contractor, operating or maintaining lab instruments be qualified to a level that allows them to do so without compromising quality hence only qualified persons are permitted access to the instruments. Quality systems require a maintenance schedule detailing how often equipm
