What are the four parts of a spectrometer
The workings of a spectrometer can be broken down into four main parts: the light source, the collimator, the monochromator, and the detector. An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument. Listed below are some of the key components that make measuring transmittance possible.

XRF Metal Spectrometer
SPECTRO is a world leader in the manufacture of energy dispersive X-ray fluorescence spectrometers. It is non-destructive and reliable, requires no, or very little, sample preparation and is suitable for solid, liquid and powdered sam.

Spectrometer Attenuation
Attenuated total reflection (ATR) is a sampling technique used in conjunction with infrared spectroscopy which enables samples to be examined directly in the solid or liquid state without further preparation. ATR uses a property of total internal reflection resulting in an evanescent wave. One advantage of ATR-IR over transmission-IR is the limited path length into the sa.

Principle of Steady-State Fluorescence Spectrometer
There are two main types of fluorescence spectroscopy: steady-state and time-resolved. The extent of the applications has benefited from the development of the Green Fluorescence Protein (GFP) family that allows for the expression of fluorescent proteins in cells and tissues; a feature that allows the experimenter to follow the whereabouts of proteins in live cells and even tissues. shows the fraction of incident light absorbed by the material over a range of frequencies.
