At Dextrose Technologies Pvt. Ltd., we offer FTIR (Fourier Transform Infrared Spectroscopy) for rapid functional group identification and material fingerprinting. FTIR is a reliable first-line tool for confirming raw materials, comparing formulations, and investigating unknowns by identifying characteristic IR absorption bands. It is widely used for polymers, excipients, organics, and contaminant screening, with clear interpretation and documentation. Functional Group Identification We identify key functional groups (e.g., O–H, N–H, C=O, C–O, C–H, aromatic bands) to support compound confirmation, comparison, and troubleshooting. Raw Material and Formulation Compatibility Studies We compare spectra of raw materials, excipients, APIs, and blends to detect spectral changes that may indicate interaction or incompatibility—useful during formulation development and material selection. Polymer, Excipient, and Contaminant Identification FTIR is effective for polymer and excipient fingerprinting and for initial contaminant identification (e.g., unknown residues, particles, films), supporting root-cause investigations and corrective actions. Deliverables * FTIR spectra with peak highlights * Sample-to-sample comparison summary (overlay interpretation) * Identification/interpretation notes aligned to your objective * Recommendations for confirmatory testing if required (e.g., GCMS/LCMS/SEM-EDX) Get started Share your sample type (solid/liquid/powder/film), objective (ID/compatibility/contaminant), and sample count. We’ll recommend the best FTIR approach and reporting format.
