Profile: PDR-Chiral, Inc. is a manufacturer of automated method development systems for HPLC, SFC, chiral and achiral compounds. Our advanced laser polarimeter measures the real-time rotation of a plane-polarized 670 nanometer laser beam as it passes through the flow cell to micro degree accuracy/resolution. Our advanced laser polarimeters (ALPs) are used in HPLC, SFC, SMB, and process applications covering analyte sizes ranging from micrograms to tons. Our AutoPrep with Gilson & Knauer collection system is a compact, fully automated prep peak collection system with advanced capabilities for unattended runs. The software uses proprietary real time algorithms to make peak detection and collection decisions so AutoPrep dynamically follows changes in retention time and loading in real time during the run. AutoPrep can collect the whole peak in a single collection channel. The AutoPrep can be installed with most pumps and UV detectors.
