DCDR is back! We are excited to bring back to the market the Drop Coated Deposition Raman (DCDR) slides, invented in the lab of Professor Dor Ben-Amotz.
• Biologics (Proteins, Peptides, DNA)
• Detection of explosives
Extremely Affordable, Ready-To-Ship*
Minimum 5 slide purchase. To purchase higher quantities, call for a discounted price.
*Online orders only, except for higher quantities.
The µ-RIM slide is a stainless steel substrate for Raman and Reﬂectance IR Spectroscopy. The highly reﬂective surface has no detectable Raman or IR background signal. This substrate is ideal for measuring small quantities of material, especially from dilute solutions in polar solvents (such as water).
When applied to the substrate, the sample will bead up and dry with a smaller diameter than when applied to an untreated surface. Universally compatible with all µ-Raman spectrometers!
Increased Sensitivity / Ampliﬁed Signal Resulting In:
• Non-Wetting Surface w/ smaller concentration
• High Reﬂectance
• Low Background
1. Micro-Raman spectra of proteins, peptides, nucleic acids, carbohydrates with µM concentrations in minutes vs mM concentrations and hours in solution.
2. ldentiﬁcation of proteins and peptides; secondary and tertiary structure, sites of phosphorylation, glycosylation, disulﬁde bonds, aromatic side chain.
3. ldentiﬁcation of micro extraction of pharmaceutical drugs and controlled substances for micro-Raman, micro-IR and ATR IR analysis by forensic scientists.
4. ldentiﬁcation of liquid chromatography fractions.
RAMAN SOLUTIONS OF PROTEINS IN WATER
Raman Spectroscopy can be a powerful probe of structure of proteins. With µ-Rim Slide™, Raman spectra can be easily obtained from the manual deposition of µL volumes of µM protein solutions.
Protein deposits on non-wetting substrates often accumulate in a circular ring formed during the evaporation process once the protein reaches its saturation concentration. This well-known "coffee ring” effect further localizes the deposited protein and thus facilitates additional detection limit improvement.
