Automatic data collection

Size exclusion liquid chromatography M) has been widely used to characterize distributions of molecular weights in polymer specimens. This paper describes a package of computer programs for automatic data collection and data reduction in size exclusion liquid chromatography (2). The programs and the environment in which they operate are carefully tailored to emphasize the interaction between the user and his data rather than the Interaction between the user and the computer. The system we describe differs from that described by Koehler et al. (J) in that all functions are performed by a stand-alone system. 

Automatic data collection and processing is becoming more and more common in modern instrumentation. This not only shortens the time for accurate evaluation of the results, but also makes it possible to take into account various experimental factors and to make necessary corrections. 

Figure 9.1 Schematic representation of a basic capillary electrophoresis system. The main components include a capillary (commonly contained within a housing that allows for temperature control), a power supply, and a detector. Automation is achieved through the use of computer-controlled setting of solutions and samples, displacement forces (to replace capillary contents and for hydrodynamic injection), and automatic data collection.

The statistical uncertainty arising from the analytical measurement is derived from the automatic data collection procedure noted before. The AGAS computer performs a standard error analysis and produces both a mean and the standard error of the mean associated with that value. A computer program is used to combine the uncertainties from the primary gravimetric process with the uncertainties produced from the standard deviation of the instrument s response for each of the gas mixtures.

The sample was mounted in an NaCl compression cell and spectra were collected automatically in 2 p,m steps along the white line indicated. A Centaurp,s Analytical FTIR Microscope System from ThermoNicolet was used for the automatic data collection and results presented in this figure and in Figs. 4.26-4.28.

For the future, there is considerable speculation that more and more of the primary information, particularly numerical data, will be recorded in data banks, rather than in printed papers. Automatic data collection techniques will facilitate this. Thus, computer retrieval of primary information, though minimal at the moment, in the long term is likely to develop considerably. 

Active control implies that the "paper on glass" documents are no longer static. Data may be collected automatically so that only a few of the data entries are manually entered, most of them are entered through automatic data capture, possibly with a border value check and some kind of compliance enforcement. This requires a certain level of integration with physical data equipment, such as control systems, instruments, bar code readers and so on, which may prevent common errors from manual data entry and additionally provide enforcement of basic quality requirements. Active control requires the paperless system to be a true application that actively assists the user s data entry with automatic data collection and possibly interfaces to other systems. 

The original design for TIP includes neutron detector and collecting information, however in the market were available an automatic TIP with Gamma detector, using computerized automatic data collecting system, that makes faster the total core power range monitor calibration, and faster startups. This concept improves the capacity factor of the plant.

A high pressure gel permeation chromatograph (GPC) has been used to monitor the performance of the reactor. A novel aspect of the GPC is that, it too, has been put on-line to the process control computer and both data collection and analysis have been made automatic while giving the operator full interactive facilities. 

Analysis of the chromatogram is carried out Interactively with the operator directing the flow of analysis from the computer keyboard, or in the automatic mode immediately after data collection to an extent specified using SETUP. Automatic analysis may also be applied to a series of chromatograms at any time by putting the run numbers or names of the files in the run number file. Before the next set of data collections, the programs check that the number in the run number file is the latest run number for all the files on the disk. 

The screening capillary viscometer can be operated manually as well as automatically. If manual operation is desired, an interactive program is available to aid with data collection. Program-operator interaction takes place through terminal input and also with a push-button data collection indicator on the instrument itself. The immediate on-line analysis of results and the ease of data storage and retrieval are just some of the benefits realized by using this program 1n conjunction with manual operation of the instrument. 

The downloading function is provided so that the user can automatically create disks that can be used to transport information from a data disk to an offline computer for further reduction. This function also writes an extract of the result archive to the output disk for use in updating the comprehensive result archive that is maintained on the remote host. The algorithms used for online data reduction are transportable to any computer that supports FORTRAN IV [which is a subset of FORTRAN 77 (4)] so that users can process their data interactively when they are unable to use the data collection computer. 

Most manufacturers of dissolution testing devices offer semi-automated systems that can perform sampling, filtration, and UV reading or data collection. These systems automate only a single test at a time. Fully automated systems typically automate entire processes including media preparation, media dispensing, tablet or capsule drop, sample removal, filtration, sample collection or analysis (via direct connection to spectrophotometers or HPLCs), and wash cycles. A fully automated system allows automatic performance of a series of tests to fully utilize unused night and weekend instrument availability. 

The water samples were analysed for pH, electrical conductivity (EC), temperature (T), dissolved oxygen (DO), redox potential (Eh), reduced iron (Fe2+) and alkalinity (dissolved inorganic carbon, DIC, as HC03") in the field. A few special water samples were collected to determine background levels of CD4, SF6 and Kr in the headspace gas. SWL and T were recorded hourly in 3 shallow (Sites H, I, R) and 3 deep (Sites J, V, W) open bores using automatic data loggers, which were downloaded biannually. 

All measured values are normally registered by means of a recorder. In addition, an improved method for data collection and processing is possible today by use of a computer. This has the advantage of automatic, safer data collection in an easy-to-read form. Comparison with standard values, correction of the buoyancy effects, control of linearity, control of standard deviations and peak integrations are thus possible.
