Harrick Scientific is excited to introduce the ConcentratIR2™, a new miniature multiple-reflection ATR accessory. Designed for micro-liquid sampling, it features interchangeable diamond and silicon ATR sampling plates. The silicon configuration offers eleven internal reflections at a nominal 30° incident angle for use from 4000 cm-1 to 650 cm-1. The diamond configuration has ten internal reflections at a nominal 45° angle of incidence, suitable for use from 4000 cm-1 to 550 cm-1. Turn-tilt mirror adjustments as well as a vertical adjustment are provided to maximize optical throughput. The ConcentratIR2™ is fully enclosed for rapid sample exchange with minimal interruption of the purge of the spectrometer. Compatible even with smaller FTIR sample compartments.
