In today's world of rapidly advancing technology, scientific breakthroughs rely heavily on our ability to visualize and understand materials at the smallest scales. One such tool of considerable importance is the field emission scanning electron microscope (FE SEM), and the CIQTEK SEM5000 stands out for its superior imaging capabilities and versatility. In this blog post, we will delve into the fa...
In the field of analytical instrumentation, both Electron Spin Resonance (ESR) spectrometers and Nuclear Magnetic Resonance (NMR) spectrometers play an important role. Although they use similar principles, there are significant differences between the two techniques. ESR Spectrometer: Electron Spin Resonance (ESR) spectrometers are employed to study the behavior of unpaired electrons within...
Scanning electron microscopes (SEMs) are highly advanced and sophisticated scientific instruments that provide high-resolution imaging and analysis of samples at the nanoscale level. There are several renowned scanning electron microscope brands available in Europe that offer state-of-the-art SEMs. Here are a few notable brands: FEI Company (Thermo Fisher Scientific): FEI Company is a leadi...

Major brands of EPR spectrometers in Korea include Jeol, Bruker, Nicolet, and CIQTEK. Below are the features and prices of these EPR companies. Jeol Features: Jeol is a time-honored brand known for its high-quality and reliable instruments. ...
ESR (Electron Spin Resonance) and EPR (Electron Paramagnetic Resonance) are used interchangeably to describe the same spectroscopic technique. The reason for the two different names can be traced to the historical development of the field and some of the interesting stories surrounding it. Originally, the technique was called ESR, or electron spin resonance. It was discovered in the mid-20t...
The Scanning Electron Microscope (SEM) is a powerful tool for various applications in material sciences, life sciences, and other fields. Different kinds of detectors have been developed to obtain more information and improve the performance of SEM. The following are a few common types of SEM detectors: Backscattered Electron Detector (BSE): BSE detectors are used to detect electrons scatte...
Scanning Electron Microscopy (SEM) is based on the principle of using a focused beam of high-energy electrons to probe the surface of a sample and produce a high-resolution detailed image. Electron Source: SEM works by using an electron source, typically a heated tungsten filament or a field emission gun, to produce a beam of electrons. Electron Beam Generation: The electron source e...
The sensitivity of a spectroscopic technique refers to its ability to detect and analyze signals from a sample. In the case of electron paramagnetic resonance (EPR or ESR) and nuclear magnetic resonance (NMR), EPR is generally considered to be more sensitive than NMR for several reasons: 1. Detection principle EPR detects signals from unpaired electrons, while NMR detects signals from the n...
