Analyses and data reporting

The methods used to analyze the corrosion monitoring data will be determined by the number, location, and variation in monitoring devices used and the method of data collection. 

Suitable computer software may be available commercially for this purpose or may be modified to suit the particular application. In selecting computer software consideration should be given to the inclusion of plant process data and plant inspection results. 

6 Guidelines for Safe On-Line Installation and Retrieval of Corrosion Monitoring Devices 

Loosen and remove the nuts holding the upper safety clamp plate. Remove the plate, taking care to ensure that the safety clamp rods are supported. 

Loosen the ferrule locking nut, taking care in case the probe or coupon holder stem is forced up through the packing gland assembly by the line pressure. 

Performing this analysis requires a close comparison between the student surveys at the begiiming and at the end of the course, arranging data in various ways in order to facilitate the analysis, and performing various statistical tests to measure performance and statistical significance.

The E9 discusses the statistical issues in the design and conduct of a clinical trial. It details trial design, trial conduct, and data analysis and reporting. Although most useful... 

Lloyd et al.1 described automation processes for compound optimization and simultaneous implementation of (1) a LIMS system to automate and track the flow of sample information, data analysis, and reporting (2) an automated data archiving system to handle a large number of LC/ MS/MS data files (3) custom software to track a large number of protocol flows and (4) workstation automation. 

An additional consideration for sample preparation is to ensure that the final sample solution is miscible with the HPLC eluent and will not alter or degrade the column.62 The total time needed for sample preparation may be longer than that required to conduct chromatographic separation and therefore becomes is the rate-determining step for the analysis.63 A survey cited by several authors indicated that on average chromatography separation accounts for about 15% of the total analysis time, sample preparation, about 60%, and data analysis and reporting, 25%.64 66... 

Australia for six months each year, and for time to obtain access permissions for some areas). Figure 3 shows the catchments sampled to 31 December 2008. Sample preparation started in early 2008 and will continue until late 2009. Sample analysis started mid-2008 and will continue until mid-2010. Data analysis and reporting are planned to take place in 2010 and early 2011. The project concludes on 30 June 2011. 

Sometimes the blind review can throw up data issues that require further evaluation by the data management group with data queries being raised, and these perhaps may result in changes to the database. This sequence of events can cause major headaches and delays in the data analysis and reporting, and so it is important in the planning phase to get the data validation plan correct so that issues are identified and dealt with in an ongoing way.

If an immunoassay technique is developed from outside the EPA, the cost of an evaluation is shared by the developer and the Agency, but the developer must provide all necessary reagents, supplies, and any specialized instrumentation. The EPA may provide personnel to conduct the evaluation, or volunteer laboratories may be used, for example, such as through the Association of Official Analytical Chemists (AOAC). The EPA is responsible for data analysis and report writing which includes a recommendation regarding the use of the particular technology. Evaluations are not undertaken as a service to the developer, but are performed to provide the EPA with new methods to fulfill analytical needs. 

Data analysis and report generation are prime examples of where productivity and efficiency of a laboratory can be greatly improved. This efficiency gain is most easily achieved with integrated or connected data systems. The transfer of data between instruments or informatics systems should be integrated and require minimal human intervention. In addition to the time spent, manual data transfer also increases the risk for errors, which ultimately may lead to inaccurate results. 

Sample preparation usually involves a protein precipitation cleanup step. Fast chromatography methods that provide run times of less than 2 min are generally preferred and attained. The LC-MS/MS method is optimized for each CYP substrate s metabolite SRM transition. The selectivity of MS/MS reduces the need for complete chromatographic resolution of individual components. Therefore, analytical run times are significantly reduced. Data analysis must be highly streamlined using automated data analysis and reporting. 

Use an integral method of data analysis and report the value of the rate constant for the rate expression that provides a suitable fit of the data. The reaction was carried out isothermaUy at 25° C with an initial HCl concentration of 4.50 mol/kg solution. 

To achieve the aforementioned aims, research was performed in three main phases (1) background research and preparation of siuveys, (2) data collection, and (3) data analysis and reporting. 

Analysis and reporting regarding data analysis and reporting, mobile research is not more rapid compared to other data collection methods. However, real-time data make it possible to rapidly get intermediate results. 

Gathering quality data, analysis, and reporting from all institutions... 

After a preparation period of one week in Delft, the fieldwork lasts about 3 weeks in Spain. Back in Delft, 2 weeks are allocated for laboratory testing, data analysis and reporting. During the whole fieldwork duration, students share responsibilities and work load. On some occasions, they have to work out conflicting interpersonal/intercultural relationships or working methods to induce efficiency and creativity. At any time, safety in the field is paramount. 

An investigation is not complete until all data are analyzed and a final report is completed. In practice, the investigative work, data analysis, and report preparation proceed simultaneously over much of the time spent on the investigation. 

Quality assurance and quality control are the unifying themes of this chapter as well as the previous one. Uni- and multivariate statistics provide the quantitative framework to measure reliability and uncertainty, two indispensable descriptors of any forensic data. Uncertainty and errors are inevitable in even the best-designed and validated method quality control and statistics provide the methods to characterize and incorporate those errors into data analysis and reporting. If problems arise during an anal5reis, quality assurance and quality control procedures and practices serve to raise a red flag and allow the forensic chemist to take corrective action. Thus, QA/QC are as much a part of forensic chemistry as are stoichiometry, organic chemistry, and sample preparation.
