The largest database of trusted experimental protocols

400 spectrometer

Manufactured by PerkinElmer

The 400 spectrometer is a laboratory instrument designed for spectroscopic analysis. It is capable of measuring the absorption or emission spectrum of a sample across a range of wavelengths. The core function of the 400 spectrometer is to provide accurate and reliable spectroscopic data for various applications in scientific research and analysis.

Fourier transformation infrared spectroscopy (FT-IR) analysis of the synthesized polymers was performed on a PerkinElmer 400 spectrometer using the attenuation total reflectance setting. The same pressure was applied on the outer surface of all analyzed samples. A number of 32 scans were recorded using a 1 cm−1 resolution. All spectra were processed using the automated baseline correction and the data auto-tune functions (see Supplementary Figs. 2529).

The crystalline
diffraction pattern
of the samples was analyzed by a Rigaku Miniflex 600 powder X-ray
diffractometer with monochromatized Cu Kα (λ = 1.5425
Å) incident radiation. FTIR spectra of the samples were recorded
by a PerkinElmer 400 spectrometer in the range 4000–400 cm–1. High-resolution transmission electron microscopy
(HRTEM) images and energy-dispersive X-ray (EDAX) spectra were taken
using a JEOL JEM-2100 microscope at an accelerating voltage of 200
kV. Dynamic light scattering was performed in a HORIBA Scientific
SZ-100. The photoluminescence measurements and lifetime measurements
were carried out using a Shimadzu RF-5301 spectrofluorometer. The
quantum yield of thin films was determined in a HORIBA FL3–211_1939C-5017-FL.
The UV–visible diffuse reflectance spectra were recorded using
a UV-2450 Shimadzu UV–visible spectrophotometer.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
