Raman-HPLC Combination
Detection of difficult components in analytical and preparative HPLC
- Distinction of different oligomers and separation of biotechnological API such as peptides, carbohydrates etc.
 - Element-specific detectors for phosphor, sulfur…
 - Chiral components
 - Impurity characterization
 - API side components
 - Stability testing by-products (hardly identifed via LC-MS stanards)
 
- HPLC column management
 - via actual separation results instead of defined retention times which is less and less reproducible with increasing age of HPLC columns
 
High Pressure Liquid Chromatography
- Standard separation technology for soluble, UV- sensitive components
 - manyfold separation techniques
 - very small amounts detectable
 
Raman Spectroscopy
- solid and solved samples possible
 - also non-UV-detectable compounds
 - Distinction of different structures at same retention time
 
HPLC and Raman Detection:
Very powerful combination of two excellent technologies
Separation of biotechnological API such as peptides, carbohydrates etc.
Reliable continuous detection of chiral components, impurities etc.
