Designated laboratories conduct

After formulating a hypothesis, scientists design further experiments—carefully controlled tests—to verify it. Designing and conducting good experiments often requires ingenuity and sometimes good luck. If the results of repeated experiments—often in other laboratories and sometimes by skeptical coworkers—support... 

The OPMBS was sponsored by a task force, consisting of major registrants of organophosphate pesticides, and utilized three contract organizations to carry out study management, design and conduct of sample collection, and quality assurance (QA). Four analytical laboratories performed the necessary residue analyses. 

It is recommended that experiments with explosive chemicals not be conducted in the confinement of standard fume cupboards, with shatterable front and side panels, but on the open bench behind anchored polycarbonate blast screens. Even light top cover is found much to increase lateral blast effects. Specially designed laboratories are, of course, much preferable for such experiments. 

Laboratory accreditation bodies also offer formal recognition (accreditation) of proficiency testing providers to ILAC-G13 2000 (International requirements for competence of providers of proficiency testing schemes). This process is intended to provide confidence that proficiency testing schemes are designed and conducted to internationally acceptable standards. 

A second strategy is to use undergraduate assistants to help manage the research projects. Students who have completed the course or interested science majors can work closely with research teams in designing and conducting research, especially laboratory components. For institutions with graduate students, teaching assistants can also be used. 

Designated laboratories or laboratories seeking designation must participate in one of the usually two proficiency tests conducted annually. The proficiency tests conducted within the same year should therefore have the same degree of difficulty in order to accommodate a fair and consistent proficiency-testing scheme among the participants. 

The OPCW Laboratory conducts a Proficiency Testing program (as described in Chapter 6) for the purpose of selecting and maintaining designated laboratories. The OCAD has been used extensively by all laboratories participating in the tests and will undoubtedly be an important reference in any event of off-site analysis. 

The Department plans to use immunoassays both as screening and quantitative analytical assays. They will be used by the Chemistry Laboratory Services Branch to analyze sanples in the same way that Branch now uses the more traditional analytical methods. The extent to which immunoassays are integrated into normal use will depend on the results of tests which are now being designed and conducted in a joint effort between the two Branches. 

Often by necessity, the potentially deleterious effects of chemical compounds must be tested in laboratory animals. For the extrapolation of animal study results to man, much care should be placed in the design and conduct of these studies, since many factors may influence their results. These factors include the dosage and frequency of exposure, route of adsdnistration, species, strain, sex and age of the animal, duration of the study, and various other modifying factors as deemed important for the particular agent and effect being studied. 

The objective of the experimental study described next was to examine whether the in situ formation of a foam occurs in primary production of heavy oils by solution gas drive. A simple apparatus was designed to conduct primary depletion experiments in the laboratory. The presence of foam within the porous matrix was inferred from the observed production and pressure-drop behavior of the system. 

Response actions other than small-scale short-duration (SSSD) repairs must be designed and conducted by accredited personneL and must be carried out as mandated by applicable worker protection and work practice laws/ Some require cleaning before initiation of the response action/ Upon completion of any response action to remove, encapsulate, or enclose ACBM, except for SSSD repairs, the area must be visually inspected and air samples collected and analyzed by an accredited laboratory using a specified method. The accreditation program is now run by the National Institute of Standards and Technology, and a list of laboratories accredited to perform... 

Petroleum chemistry is very complex and very sensitive to error when translated to the laboratory. Great care must be taken when designing and conducting corrosion tests for the petroleum environment to ensure that the corrosion...
