Product Overview
The PIKE AutoDiff II™ is a premier automation solution for laboratories requiring high-throughput diffuse reflection infrared Fourier transform spectroscopy (DRIFTS). Engineered to minimize manual intervention, the system features an advanced R-theta sampling stage that facilitates the seamless analysis of large sample batches. This makes it an essential tool for high-volume applications such as pharmaceutical quality control, forensic screening, soil characterization, and the analysis of kidney stones, where consistent data acquisition and laboratory efficiency are paramount.
The optical architecture of the AutoDiff II utilizes a high-efficiency fixed ellipsoidal reflector to maximize the collection of diffusely reflected radiation while minimizing specular interference. This design ensures that even low-absorbing or highly scattering powders yield high-definition, research-grade spectra. The entire unit is baseplate-mounted for permanent alignment and can be independently purged or integrated into the spectrometer’s internal purge system. For researchers working in the Near-IR or seeking peak performance in the Mid-IR, an optional gold-coated optics version is available to further enhance signal-to-noise ratios.
Efficiency is driven by the PIKE AutoPRO™ software, an intuitive graphical interface that manages multi-operator sample submissions and automated sequencing. The software allows for flexible background collection intervals, which are critical for eliminating atmospheric contributions (H2O and CO2) in long-duration unattended runs. With its removable 60-position sample tray, the AutoDiff II streamlines the transition from sample preparation to final reporting, providing a robust and reproducible platform for high-throughput molecular analysis.
