Chemical-free and fast determination of surfactants in shampoo

6 Apr 2020

In this application note, Metrohm demonstrates how the DS2500 Analyzer, operating in the visible and near-infrared spectral region (Vis-NIR), is designed to provide a cost-effective and fast solution for the simultaneous determination of sodium laureth sulfate (SLES), cocamidopropyl betaine (CABP), cocamidopropylamine oxide (CAW), cocamide diethanolamine (DEA), and carbopol in shampoo.

NIRS DS2500 Analyzer

Metrohm AG

With the compact NIRS DS2500, near-infrared analysis has taken yet another step into the future of routine analysis. This dedicated analyzer offers exceptional accuracy across a broad wavelength range of 400 to 2500 nm and is designed for routine analysis along the entire production chain. The predispersive Monochromator technology now being utilized in the NIRS DS2500 guarantees a high degree of versatility and stability across the entire spectral range from 400 to 2500 nm. With the maximum possible signal-noise ratio, the NIRS DS2500 simply performs, in less than one minute, analyses of both sophisticated and low-level parameters that must be very accurate. The NIRS DS2500 was created as a high-performance instrument for harsh production environments. Robust, easy-to-use and IP65 certified, it withstands humidity, dust, vibrations and temperature fluctuations.   NIRS DS2500 Analyzer Features: Compact analyzer for reflectance measurements Maximum optical performance across the entire wavelength range (400 - 2500 nm) Matching results, even in difficult environments Network-capable via LAN (local) or direct PC connection New predispersive Monochromator Optional sampling accessories

Near Infrared SpectroscopyNear-infrared (NIR) spectroscopy measures the interaction of near-infrared light with a sample, including transmission, reflectance and absorbance, facilitating the identification of analytes. Measurements can be conducted using a Fourier-transform near infrared (FT-NIR) spectrometer, while there are also UV-Vis- NIR spectrophotometers that measure a broader spectrum of wavelengths.
