The design of the new DA 7250 near infrared (NIR) instrument incorporates non-moving optical components, internal temperature stabilization, a static hard drive encased in an IP65-rated housing. The DA 7250 removes and reduces many sources of errors common to other NIR instruments. It employs a large spot-size, an even larger analysis area, averages many sub-samples, and uses high-energy throughput diode-array optics to ensure accurate and representative analysis of heterogeneous samples. Applications include dairy, grain processing, feed, flour, oil seeds, starch and ethanol production. The system handles grains, powders, pastes, slurries and liquids on sample sizes from a few grams up to 350 g. — Perten Instruments, Stockholm, Sweden
