The SMA-USP Flowcell – Ultra Short Path Flow Cell for Optically Dense Samples

The SMA-USP Flowcell - The new SMA Ultra-Short Path Flowcell allows absorbance measurements through an optical path length as short as 100 microns. The maximum path length available is 2000 microns.

The SMA-USP flowcell is ideal for measuring the UV/VIS/NIR (170 to 2700 nm) absorbance of optically dense fluids. Eliminates or minimizes the need for pre-dilutions during online monitoring. Wetting surfaces are Fused Silica and Teflon making this flowcell compatible with a host of chemicals including various types of weak to moderate bases, acids and solvents. Connects to fiber optics with SMA terminations.

Multiple "channels" are also available, where various optical paths must be utilized simultaneously. This is often required when measuring different components from a single source.

Please contact FIAlab for optional accessories such as thermostatic heating.
