Optical Emission Spectrometer
Optical emission spectrometry involves applying electrical
energy in the form of spark generated between an electrode and a metal sample,
whereby the vaporized atoms are brought to a high energy state within a
so-called “discharge plasma”. Sample material is vaporized with the
testing probe by an arc spark discharge. The atoms and ions contained in the
atomic vapor are excited into emission of radiation. The radiation emitted is
passed to the spectrometer (arc spark OES) optics via an optical fiber, where
it is dispersed into its spectral components
CCD / CMOS
CMOS (Complementary Metal Oxide Semiconductor) and CCD (Charged-Coupled Device) detectors are solid state detectors that convert incident photons into electrical signals. The fundamental advantage of these detectors stems from the fact that – as solid-state devices, they are extremely compact and each detector has thousands of pixels – each of which is, in effect, a detector as each pixel’s output can be individually measured. Hence, technically, a 2048-pixel detector covers 2,048 separate wavelengths. Given the extremely compact size of these detectors, therefore, a spectrometer using these detectors can cover every wavelength of light, without making the compromises that PMT detectors mandate.
Vaccum
Proper maintenance is critical for the longevity of a vacuum pump. On an annual or semi-annual basis, the oil used to lubricate the pump components must be changed along with the alumina beads used to filter oil particulates. Premature wear occurs from excessive heat generated by the running pump; degraded oil viscosity and a clogged oil mist filter element are the leading cause of pump failures. During operation, the fan shroud collects dust from the fan moving air over the pumps cooling fins. Removing the built-up dust from the shroud increases the pumps cooling capacity and helps maintain the pumps functionality.
