S <br /> f <br /> r� <br /> INTRODUCTION <br /> Definition: <br /> A Quality Assurance Program is an organization-wide network <br /> designed to ensure that data produced within that network <br /> conforms to the highest standards set by state and/or federal <br /> regulations. The network functions at the management level <br /> through company goals and management policies; it functions <br /> at the analytical level through standard operating procedures <br /> and quality control. These two levels are spanned by data <br /> control and the reviewing process. The end result is a data <br /> �. package that is accurate, reproducible, and is presented in <br /> such a way as to be most useful to the client. <br /> Scope: <br /> Sequoia Analytical analyzes thousands of environmental and <br /> industrial samples every month. Chemical, physical, and <br /> biological parameters must often be measured on the same <br /> % sample. As such, the Quality Assurance Program must be able <br /> to accommodate the complications implicit in the analysis of <br /> many samples of widely varying matrices. <br /> Purpose: <br /> The Quality Assurance Program provides a means by which the <br /> integrity of data can be verified. Because industrial, <br /> engineering, and environmental decisions are based on the <br /> J' data produced, it is essential that clear and extensive <br /> verification procedures exist. Accuracy, precision, <br /> completeness, and representativeness are all aspects of a <br /> data package that verify the integrity of the analysis. <br /> - The Quality Assurance Program is also a useful historical. <br /> document. The chronological development of any Quality <br /> Assurance Program relies on the adequate docua'_ntation of <br /> previous programs. Improvements and modifications can `ie <br /> _ instituted only if an established frame of reference -, ;ts <br /> and the comparative efficacy of such cY:<; .? s can be ju_7.;td. <br /> _ Lastly, the Quality Assurance Program is the format throe':1 <br /> which Sequoia Analytical can express its goals, policies, and <br /> commitment toward the generation of data of the highest <br /> s � <br />
