Mikroanalüüsisüsteemid

Mikroanalüüsisüsteemid, also known as microanalysis systems, refer to a range of techniques and technologies used for the elemental and chemical analysis of very small sample volumes. These systems are designed to provide detailed compositional information at the microscale, often down to the micrometer or even nanometer level. Key technologies within this field include electron probe microanalysis (EPMA) and energy-dispersive X-ray spectroscopy (EDX/EDS), often coupled with scanning electron microscopy (SEM). These methods typically involve bombarding a sample with a beam of electrons, which then causes the emission of characteristic X-rays from the elements present. The energy and intensity of these X-rays can be measured to identify and quantify the elemental composition of the sample. Other techniques like micro-Raman spectroscopy and micro-X-ray fluorescence (micro-XRF) also fall under the umbrella of microanalysis systems, offering complementary information about molecular structure and elemental distribution, respectively. The development of microanalüüsisüsteemid has been crucial for advancements in various scientific disciplines, including materials science, geology, biology, and forensics, where the ability to analyze tiny samples with high spatial resolution is paramount for understanding material properties, identifying contaminants, or studying cellular structures. The miniaturization and increasing sensitivity of these systems continue to push the boundaries of analytical chemistry and material characterization.
