X-ray Fluorescence (XRF) is a technique which probes the elemental composition of a material. In this interview, Bruce Scruggs, from EDAX talks to AZoM about the XLNCE SMX product line and its capabilities for performing XRF measurements in a process control environment.
In fluorescence microscopy, a specimen emits energy when activated by light of a certain wavelength. Some substances such as chlorophyll and some minerals will do this naturally, while others will need the help of other chemical triggers.
When a molecule absorbs light, electrons in its constituent atoms become excited and are promoted to a higher energy level. When electrons in this excited state lose energy and return to the ground state, they release this energy in the form of heat or radiation. Light emitted during this process is known as fluorescence, and the molecules that show this activity are called fluorophores.
Immunostaining is a complex technology and subject to several technical obstacles, which could mean that after a lot of time and effort the result is either no signal or one which is impossible to interpret, instead of a clear and well defined set of images.
The LUNA-STEM™ is a dual fluorescence automated cell counter that measures cell number and viability. The most advanced fluorescence optics and analysis software enables the LUNA-STEM™ to accurately count nucleated and non-nucleated cells such as stem cells and cells in the stromal vascular fraction (SVF), setting itself apart from other cell counters.
