Gemini Analyzer with LowDoseID
Manufacturer – Thermo Fisher Scientific
Description: Gemini Analyzer with LowDoseID from Thermo Fisher is a rugged, handheld instrument that combines FTIR and Raman (including SERS) spectroscopy for rapid, confirmatory chemical identification in the field. With the LowDoseID enhancement, it can detect and identify low-concentration illicit drugs (as low as 1–10%) in mixtures and tablets.
