Optosky's ATP8900Plus and ATP8900Plus-Laptop are truly portable FTIR spectrometers purpose-built for high-performance chemical analysis in even the most demanding field environments. The handheld ATP8900Plus weighs just 2.5 kg including battery, yet packs research-grade capabilities into its rugged, moisture-resistant housing designed to withstand harsh conditions. 

At its core is a high-stability cube corner interferometer with over 10 years of service life, delivering a wide spectral range from 7800 - 350 cm^-1 with resolution down to 1 cm^-1. What sets the ATP8900Plus apart is its innovative plug-and-play measurement module design with a unique sliding-type fastener. This allows for rapid switching between ATR (diamond, ZnSe, Ge), transmission, diffuse reflectance, and other sampling accessories to analyze diverse sample types on-site. 

The ATP8900Plus-Laptop takes portability even further by integrating the ATP8900Plus' powerful FTIR engine into a compact, mobile laptop form factor. This intelligent design includes built-in temperature control, permanent vertical interferometer, and customizable gas cell path lengths based on concentration needs. Whether for gas monitoring, material identification, product inspection or other critical applications, the ATP8900Plus-Laptop delivers lab-quality results in the field. 

Both models feature easy-to-use software with complete analysis functions and the ability to match samples against extensive reference libraries. They satisfy stringent qualification standards like DQ, IQ, OQ, PQ for regulated industries. With their robust construction, high spectral performance, versatile sampling options and advanced software, the ATP8900Plus series provides the ideal portable analytical solution across many sectors.
