IR-DOSY and Raman-DOSY chip: IRMA
The IRMA liquid sample cell is a versatile tool engineered for advanced Infrared (IR-DOSY) and Raman Diffusion-Ordered Spectroscopy (Raman-DOSY) measurements.
The cell features a robust, standardized metal frame but offers flexibility in its sandwich sample insert materials to ensure optimal performance for your specific technique.
For IR-DOSY: The insert is made of Calcium Fluoride, which is essential for its excellent transparency in the mid-infrared range where most functional groups absorb.
For Raman-DOSY: The insert is made of Fused Silica, which is preferred for its low background fluorescence and high chemical resistance, crucial for clear Raman signals.
Available Spacer Thicknesses (Pathlengths): 0.050 mm, 0.1 mm and 0.230 mm.
