    Mass spectrometry is used in conjunction with chromatography for environmental screening processes. Mass spectrometry methods are generally used for analysis of environmental contaminant monitoring, particularly in aquatic environments (though they can be applied in non-aquatic environments, such as with screening pesticides on plant matter [9]), paired with chromatography for separation.

    Using a computer and a photo editor between the scanning and the printing process provides the artist with a greater level of control, allowing, at a minimum, the ability to "clean" the image by removing specks and other imperfections in the capture. With the increased availability and affordability of flatbed color scanners in the 1990s ...

    X-ray computed tomography (CT), or Computed Axial Tomography (CAT) scan, is a helical tomography technique (latest generation), which traditionally produces a 2D image of the structures in a thin section of the body. In CT, a beam of X-rays spins around an object being examined and is picked up by sensitive radiation detectors after having ...
