Validation and approval of analytical data are based on a well-designed and regularly applied quality assurance quality control QA QC program. The components of this program are divided into a management QA and a functional QC part. Quality Assurance is a laboratory operation program of specified standard procedures that are aimed at producing data of defensible quality and highly reliable reported results. Quality Control consists of a set of measures within a sample analysis methodology to ensure that the process is controlled. Laboratory personnel develop their own QA QC program which should be delineated in a QA QC manual. The program should be strictly enforced continually reviewed and updated as needed. Large laboratories typically have a QC control officer or group independent of laboratory management charged with oversight of the QA QC program. Quality assessment is the mechanism for verifying that a laboratory system is operating within acceptable limits. This mechanism consists of all activities aimed at providing assurance that the overall quality control job is being done effectively. Each laboratory develops its own QA program which should be delineated in a QA QC manual and should be comprehensive enough to apply to most operations. This program should be continually reviewed and updated as needed. The laboratory should also have a separate QA project plan for each project. Understanding the QA program helps analysts to be responsible participants in the laboratory system in order to produce defendable precise and accurate analytical data. GLASSWARE USED IN METALS ANALYSIS The mainstay of a modern analytical laboratory is a highly resistant borosilicate glass such as Pyrex or Kimax. Corning-brand glassware is highly resistant to alkalis and practically boron free. .
