The ReSpect4π Fourier transform Near‐infrared spectrometer is made for real‐world analyses and environments. The spectrometer is sufficiently small for field use and is made for inhomogeneous samples. The sampling area is up to 30 cm diameter. The ReSpect4π FT‐NIR spectrometer has been proven to work reliably in adverse operating conditions.
LLS Instruments is able to provide assistance to those clients who require help in the development of chemometric methods. Given appropriate standards, extremely robust models can be produced. We also provide training to educate clients in appropriate sampling methods, how to treat samples, and how to measure samples correctly.
We are able to assist clients with sampling issues, selection of appropriate standards, guidance for the appropriate analysis of standard samples, and verification of the data for robust models. In addition we can assist with engineering issues to install spectrometers for optimized data collection.

LLS Instruments manufactures Fourier transform near‐infrared (FT‐NIR) spectrometers. The spectrometers are specifically designed to measure inhomogeneous materials, such as agricultural and food products. The spectrometer measures large areas efficiently so that representative averages of the components in a sample can be determined accurately. The instruments are designed to measure areas up to approximately 30 cm in diameter. The sample area is integrated and larger samples may be scanned by moving the instrument across the sample, or moving the sample in front of the spectrometer.
The instrument is a fully functioning FT‐NIR spectrometer with resolutions between 32 and 1 cm-1. It is equipped with an extended range InGaAs detector with a standard range of 8000 to 4000 cm-1, although signal can be acquired as high as 9000 cm-1. The instrument is robust and can operate in environments from -40 to +40°C, is vibration tolerant, and meets IP-67 specifications.
Woody earned his B.S. in Chemistry in 1964 at the University of North Georgia and his Ph.D. in Chemistry from the University of Georgia in 1969. He worked at the U.S. Department of Agriculture's Agricultural Research Service for 37 years where he was Research Scientist, Research Leader, Area Director, Center Director, and Location Coordinator. Woody has extensive experience in the areas of NIR spectrometery and chemometrics. He is a Fellow of the International Council for Near Infrared Spectroscopy and a Fellow of the Society for Applied Spectroscopy.
Jim joined the faculty in the Department of Chemistry at the University of Alabama in 1979, and moved to the University of Georgia in 1983. He retired as a Professor of Chemistry in 2009. Jim earned his B.S.Chem. degree from the University of Illinois at Chicago (1972) and his Ph.D. at the University of North Carolina at Chapel Hill (1977).
