The Model 341LC is an instrument package consisting of a Model 341 Polarimeter with additional filter for 302 nm and special polarimetric HPLC flow-cells for use as a selective polarimetric HPLC detector.
The Model 341LC Polarimeter uses the proven optical null principle with automatic rotation of the analyzer, which has been the basis of PerkinElmer's reputation for excellence in polarimetry. This principle is combined with state-of-the-art microprocessor electronics to produce an instrument offering the highest possible accuracy and precision with simple operation and handling.
Specifications:
Built-in mercury and sodium lamps, wavelength selection by turret-mounted filters (589 nm (NaD), 578 nm, 546 nm, 436 nm 365 nm and 302 nm spectral lines). Four spare positions for additional mercury line filters. Two selectable aperture stops for standard cells and microcells. UV-transmitting Glan-Taylor calcite polarizer prisms. Microprocessor electronics. Optical null system with automatic rotation of the analyzer, range of rotation +/- 85°. Internal angular resolution: 0.0001°. Display of results in angular degrees, as specific or molar rotation or in °Z of the International Sugar Scale and with user defined factors. Automatic gain control, digital signal averaging with 10 selectable integration periods. Menu-oriented user interaction via integrated touch keys, multilingual. The instrument includes a parallel and a serial port (Centronics and RS-232C) for the connection of printers and data systems, an interface for a PC/AT keyboard and a barcode reader and an analog output for chart recoders (four recording ranges). GLP compliant report. Additionally, the instrument provides inputs and outputs for hardware control signalsInstrument package for the selective detection of optically active compounds in HPLC. The Model 341LC also contains one additional interference filter for 302 nm for increased sensitivity, one each 40 µL and 80 µL polarimetric LC flowcell, and alignment cell. The instrument can be equipped with additional interference filters for UV lines of the Hg spectrum.
