Since no two compounds produce the same Raman spectrum
, the measurements are unique, almost like a fingerprint.
Subject VZ supply is 5 pcs portable spectrometers on the principle of the Raman spectrum
, including software support during the warranty period, the basic set of supplies and staff training.
For instance, in the Raman spectrum
of chalcedony, the band at 501 [cm.
A typical Raman spectrum
was measured on film deposited on alumina membrane by filtering the graphene dispersion under vacuum.
It was not a simple tool because the LASERs used, mostly in the visible wavelength range, cause major fluorescence interference, often overwhelming the "pure" Raman spectrum
The concentration of the cured alpha resin could also be followed thanks to the presence in its Raman spectrum
of a strong characteristic band at 1,387 [cm.
of each oocyte was obtained by averaging the point spectra of the three line scans.
Next, we obtained a Raman spectrum
of an unsaturated calcium perchlorate solution (brine) with a concentration of about 600 g/L and a saturated brine, both at ~255 K.
About 50mg of solid sample was placed on a microscope slide, and the Raman spectrum
recorded using a Renishaw Raman Microscope System RM1000 equipped with a diode laser providing the 785nm line, a Leica microscope, an electrically cooled CCD detector and a notch filter to eliminate elastic scattering.
The Raman spectrum
(obtained with a Thermo Scientific DXR Raman microscope) of the 1.
For researching of changes in conformation Hb we analyzed characteristic frequency in the Raman spectrum
of all eight batches was analyzed by Wi tec Inc.
