Used VARIAN NMR #9210752 for sale

VARIAN NMR (Nuclear Magnetic Resonance) is a popular and versatile spectrometer used for performing a variety of experiments including qualitative and quantitative analysis, reaction monitoring, and metabolomics. This technology is widely used in biochemical, pharmaceutical, medical, and chemical research applications. NMR spectrometer consists of a superconducting magnet (which provides the necessary magnetic field necessary for the experiment), RF (Radio Frequency) transmitter and receiver, a Probe (used to transmit and receive radio-frequency signals to and from the sample under investigation), an autosampler (for the introduction and withdrawal of the sample from the spectrometer), and a computer system for data collection and analysis. The user can adjust the frequency to detect the desired nuclei, which are then sent to a screen. When VARIAN NMR sample is placed in the instrument, the application of an external magnetic field to the sample causes the nuclei of the atom associated with the sample to become aligned in either the positive or negative direction of the magnetic field. When RF signals of different frequency are used to perturb the sample, the nuclei of the atom individually jump to a higher energy level and then back down to the original energy level. This spin flip leads to the emission of an NMR signal called a Resonance Frequency. By tuning to the appropriate frequency, the signal from the particular nucleus being investigated can be detected by the RF receiver. The data is then processed by computer software to analyze the signal by integrating its area, calculating its peak-width and shape, and extrapolating its chemical shift values. The data can also be compared to previously collected information, such as spectra of known compounds. This data can then be plotted onto a two-dimensional graph that can be used to compare the results of different experiments. VARIAN NMR spectrometer is easy to use and can also be used to study a wide range of chemical processes, from the investigation of molecules for basic research, to the diagnosis of diseases where biomarkers can be used to re-configure and optimize drug interactions and treatments. Its reliable, precise, and accurate characterizations make it a preferred choice when investigating complex or rapidly changing molecules.
