What does a Microspectrophotometer do?
What is a Microspectrophotometer. The UV-visible-NIR microspectrophotometer is designed to measure the spectrum of microscopic areas or microscopic samples. It can be configured to measure the transmittance, absorbance, reflectance, polarization and fluorescence of sample areas as smaller than a micron.
What two items make a microspectrophotometer?
A microspectrophotometer integrates a microscope and a spectrophotometer for broad coverage in the ultraviolet-visible-infrared region.
What role might a Microspectrophotometer play in a forensic investigation?
A microspectrophotometer can also be used to figure the chemical composition of something, like a paint chip. The spectral fingerprints gleaned from evidence collected from a crime scene can then be compared to samples collected from a suspect’s car, clothing, and so on.
What is a visible light microspectrophotometer?
Visible microspectrophotometry is a very useful tool in the forensic analysis of many kinds of trace evidence . It combines a microscope with a spectrophotometer so that the light absorption properties of a very small sample can be recorded.
What is microspectroscopy?
Microspectrophotometry or Microspectroscopy combines the visualization of a standard microscope with the analytical tools of a spectrophotometer for material characterization on a microscopic scale.
What is the visible light microspectrophotometer?
Visible microspectrophotometry is a very useful tool in the forensic analysis of many kinds of trace evidence . It combines a microscope with a spectrophotometer so that the light absorption properties of a very small sample can be recorded. They will absorb, transmit, or reflect specific frequencies of visible light.
Which statement best describes a microspectrophotometer?
Which of the following statements best describes a microspectrophotometer? It can be used to obtain the absorption spectrum of a specimen.
What is forensic SEM?
Electron microscopy (EM) has a wide variety of applications in forensic investigation. Numerous crime-scene micro-traces, including glass and paint fragments, tool marks, drugs, explosives and gunshot residue (GSR) can be visually and chemically analyzed with scanning electron microscopy (SEM).
What is UV visible Microspectrophotometry?
The UV-visible-NIR microspectrophotometer is designed to measure the spectrum of microscopic areas or microscopic samples. It can be configured to measure the transmittance, absorbance, reflectance, polarization and fluorescence of sample areas as smaller than a micron.
What makes the visible light Microspectrophotometer a convenient tool?
The visible light microspectrophotometer is convenient tool with which to compare the color of fibers because: very small samples can be compared, fibers can be studied right on microscope slide, fibers are not destroyed. Stereoscopic microscopes are useless in a forensic investigation or lab.
Why is the chain of custody important?
The chain of custody is the most critical process of evidence documentation. It is a must to assure the court of law that the evidence is authentic, i.e., it is the same evidence seized at the crime scene. Although it is a lengthy process, it is required for evidence to be relevant in the court.
