Quality control practices

Adopt and follow stringent quality control practices. 

Calibration is a very critical component of quality control practices. If the measuring devices are not giving the response for a standard that they are expected to give, they cannot be expected to give an accurate response for an unknown sample. Uncalibrated equipment ensures an inaccurate result. 

Intralaboratory Quality Control. In its efforts to establish minimum intralaboratory quality control, the USEPA has incorporated certain mandatory quality control practices into each of the 600-series organic methods promulgated as part of final rule making on October 26, 1984 (10). These quality control practices are found in Section 8 of each EMSL method. 

Interlaboratory Quality Control. In addition to the mandatory quality control practices just outlined, the laboratory is encouraged to participate in interlaboratory programs such as relevant performance evaluation (PE) studies, analysis of standard reference materials, and split sample analyses. Participation in interlaboratory analytical method validation studies is also encouraged.

The first article is from the plenary lecture given at the symposium by the symposium chairman Kishore Nadkami, It covers total quality management practices advocated for obtaining a perfect analysis. Proper staff training, sampling, calibration and quality control practices, adherence to test method details, participation in proficiency testing, accreditation from national bodies, benchmarking, etc., are some of the critically important approaches that need to be taken to achieve the ideal state of analytical Zen perfection. 

Quality control is more an application of knowledge than a tangible product. Sound quality-control practices are founded on the basic human desire to have access to the same goods and services that are available to others. The response of suppliers of those goods and services has been the development of methods to ensure that each unit of a good or service is as uniform as possible. These methods make...

Use of acid additives that are incompatible with one or more other additives or incompatible with the formation or formation fluids can cause damage, sometimes irreversibly. This problem can be eliminated with proper additive selection (see chapter 6) and quality control practices (see chapter 16). 

It is then necessary to determine if a treatment placement method must be employed mechanical, chemical diversion, or a combination. The final steps are taken after the design procedure is determined and the acid job is to be pumped. Proper treatment execution and quality control practices...
