BioXAS-Side is adequate for high concentration and ambient temperature samples. Please contact the beamline scientists for more information.
BioXAS-side beamline has a 5 mrad separation from the central line. The Side beamline is similar to the Main beamline and differs in some of the optical components as outlined below.

Typical achievable flux
The plot of energy vs flux shows the typical flux achievable in the whole operational energy range (5-32 keV) for the Side beamline. Note: the flux drops noticeably at the edges of the range, but it's still usable for samples with relatively high concentrations of the elements of interest.
Reference Foils
Reference foil spectra captured on bioXAS-Side in transmission mode. The resolution is comparable to those reported in the literature for typical Spectroscopy Beamlines.
