Raman spectroscopy can be combined with optical confocal microscopy to generate a new analytic technique called Raman microscopy. Light microscopy has several advantages: it can be used to observe ...

Fluorescence spectroscopy has great sensitivity, allowing scientists to detect signals from single molecules. But it has limited chemical specificity, making it hard sometimes for researchers to ...

Rapidly analyzing samples for the presence of bacteria and similar organic structures is generally quite a time-intensive process, with often the requirement of a cell culture being developed.

Flow cytometry is an established technique for counting and characterising cells, including blood, stem and cancer cells in biomedicine. The principle involves illuminating cells while they pass along ...

During light scattering, the majority of scattered light undergoes no change in frequency (or energy), in a process referred to as referred to as elastic or Rayleigh scattering. Raman spectroscopy ...

Spectral resolution is the most important feature of a spectrometer. This parameter determines the maximum number of spectral peaks that can be achieved using the system. For example, in the case of a ...

A medium-sized refinery lab can process 250 samples per day, whereas a big refinery can process up to 500 samples daily. Gas chromatographs, simulated distillation, flash and freeze point devices, ...
