Analysis program

The acquisition sequence is as follows a first acquisition calibration enables the acquisition operator to verify the data before storage. The row data, together with calibration files are transferred to the analysis program. The program transforms the row data into calibrated data, which is then analysed.

The relative simplicity of tlie method and the penetrative nature of the x-rays, yield a technique that is sensitive to elements with Z > 10 down to a few parts per million (ppm) and can be perfonued quantitatively from first principles. The databases for PIXE analysis programs [21, 22 and 23] are typically so well developed as to include accurate fiindamental parameters, allowing the absolute precision of the technique to be around 3% for major elements and 10-20% for trace elements. A major factor m applying the PIXE teclmique is that the bombardmg energy of the... 

CHEOPS (we tested Version 3.0.1) is a program for predicting polymer properties. It consists of two programs The analysis program allows the user to draw the repeat unit structure and will then compute a whole list of properties the synthesis program allows the user to specify a class of polymers and desired properties and will then try the various permutations of the functional groups to find ones that fit the requirements. On a Pentium Pro 200 system, the analysis computations were essentially instantaneous and the synthesis computations could take up to a few minutes. There was no automated way to transfer information between the two programs. 

The EPA Contract Laboratory Program (CLP) has responsibility for managing the analysis programs required under the U.S. Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The approved analytical methods are designed to analyze water, soil, and sediment from potentially hazardous waste sites to determine the presence or absence of certain environmentally harmful organic compounds. The methods described here all require the use of GC/MS. 

The analysis programs of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) are managed through the EPA s Contract Laboratory Program (CLP). 

Before a source analysis program is undertaken, it is important to decide which information is really required. Sampling sites must be selected with care. Choice of the site can significantly affect accuracy and cost. Care must also be taken in the selection of sampling points at the site. Measurement usually involves the deterrnination of temperature, concentration, and characterization of the gas contaminants. It also requires the mass rates of emission of each contaminant, therefore concentration and volumetric flow data are required. 

The second method for mixture analysis is the use of specialized software together with spectral databases. We have developed a mixture analysis program AMIX for one- and multidimensional spectra. The most important present applications are the field of combinatorial chemistry and toxicity screening of medical preparations in the pharmaceutical industry. An important medical application is screening of newborn infants for inborn metabolic errors.

Dr. Howard Lambert of Lawrence Livermore National Laboratory and FT A Associates, 3728 Brunell Dr., Oakland CA, 94602, e-mail lambert8 llnl.gov, provided the public domain codes FTAP (fault tree analysis program) and companions. He authored some of the codes, was associated with their development, teaches and consults for PSA. 

The MARS software is adapted and compiled specifically for a given application. The software is organized into modules which can be interchanged as needed for a particular implementation. Most modules comprise a core of management, analysis, reporting, and plotting functions which are used for every implementation. For each application, a data acquisition module is adapted to suit the appropriate instrumentation. In addition, specialized analysis programming is added if required. The acquisition module, the core modules, and the specialized analysis modules, if any, are then linked into a customized application specific version of MARS. 

There are two ways in which data can be analyzed using the MARS system. The first is through use of the general data analysis tools which are part of the standard MARS shell. The second is by means of specialized data analysis programming which can be invoked by the MARS shell. 

Figure 1. Flow chart of the Polymer Analysis program. The program Is entered from a larger program, NMRl. A database must be chosen or created for the spectrum at hand and a statistical model chosen. Options In the main menu Include calculation of probabilities associated with the model, simulation of spectra, and modification of the peak table or database.

Dr. Charles Dumoulln is acknowledged for writing the original version of the Polymer Analysis program. Annmarie Lareau made some revisions and documented the code. 

Step 5. After the simulation, you can find the report file in the CAOutput directory. At this point you may wish to rename the output file so that you can relate it to the specific settings employed. You may also wish to remove this file from the CAOutput subdirectory so that this directory does not become too crowded. If you wish to perform a statistical analysis of the simulation data, you can import the data into an appropriate statistical analysis program, such as Microsoft s EXCEL ...
