Data, acquisition storage

The signals from the detectors are amplified to create a voltage pulse with amplitude proportional to the energy of the charged particle. Data acquisition, storage and display is effected by an MCA providing pulse-height analysis. 

The experiments described here were performed with a Digilab FTS40 Fourier transform instrument, with a liquid nitrogen-cooled Mercury Cadmium Telluride, (MCT), detector. The instrument is provided with a computer for data acquisition, storage and mathematical treatment. P-polarized incident light was obtained by means of an A1 wire-grid polarizer supported on a BaF2 substrate. 

Data Acquisition, Storage, and Display. Fourier-transform spectrometers require access to an on-line computer in order to permit rapid transformation of interferograms to spectra, and, in fact, the development of commercial instruments was in large...

Instrumentation. The electrochemical cells described in the preceding section can be used. A cell design with a significantly reduced radiation absorption of the electrolyte solution film as used for specular X-ray reflectivity measurements (see description below Fig. 6.10) can also be used. Electrode potentials are selected based on standard electrochemical experiments (e.g. cyclic voltammetry) with respect to well-defined changes of the electrode-solution interface (e.g. potential steps between potentials of complete desorption and maximum adsorption). Control of the potentiostat and the X-ray diffractometer as well as data acquisition, storage and manipulation are done with a suitably programmed computer. 

The behavior can be videotaped or scored by one or two observers, or automated versions are computer linked for data acquisition, storage, and retrieval (Fig. 2). 

The bottom line question that summarizes aU of these is, How does one design a data model and data description language to enable efficient and effective data acquisition, storage, and use There are many related questions one concerns the design of what are called standard query languages (SQLs) such that it is possible to design a specific DBMS for a given application. 

Depending on the objectives of the analysis, the mass spectrometer will be operated in various modes of data acquisition such as MS, tandem MS or MS/MS, selected ion monitoring (SIM), multiple reaction monitoring (MRM), fiill-scan or limited mass range, data dependent, and so forth. SIM/MRM conditions will improve the detection limits, while data-dependent MS/MS acquisitions will worsen them. The data acquisition/storage speed and the number of averaged spectrum are all factors that will ultimately affect the detection limits.
