| Abstract: | In analytical research laboratories, the problem of quality assurance is more difficult to solve than in laboratories devoted exclusively to routine analysis: the former usually have to deal with a much greater variety of samples and may have to develop entirely new methods of analysis. For research laboratories we have developed several alternative methods of quality assurance. These methods can be used to distinguish between different analytical methods, between different types of equipment, between different levels of skill among laboratory technicians, or even between the performance of technicians of the same level of skill. |
