PerkinElmer 343 Polarimeter
PerkinElmer · 343 · 2001 · ref ML-30FA69CF
Description
Polarimetry is an important technique for the investigation and analysis of optically active substances. Common applications include: Characterization of newly synthesized compounds Quality control of pharmaceutical drugs Precise quantitative analysis of sugars Selective detection of optically active components by HPLC Monitoring and control of enzymatic reactions Principle: Automatic precision Polarimeter with optical null principle by rotation of the analyzer; automatic gain control. Radiation: Na spectral lamp Spectral lines: Selectable from instrument keypad (Na 589 nm) Apertures: Selectable apertures for standard cells and microcells. Detector: Photomultiplier 1P28A. Polarizer and analyzer: Vis-transmitting polarizers Rotatory range: ± 85° Balancing speed: 1.3°/s at 50 Hz; 1.5°/s at 60 Hz. Accuracy: ± 0.002° for rotations ≤1º; ± 0.2% for rotations >1° Reproducibility: Better than 0.002° (for zero and rotational reading). Internal angular resolution: 1 x 10-4 º Integration times: 0.1s, 0.2s, 0.5s, 1s, 2s, 5s, 10s, 20s, 50s and 100s. Autozero setting: Electronically from instrument keypad at any desired position in the rotatory range. User interaction: Either menu-driven from integrated touch-keys (English, German, French, Spanish and Italian), or PC-controlled from POL WinLab or POL WinLab ES software. Display: Stand-alone operation: vacuum fluorescence display, two lines with 20 characters each. Format of results: Selectable from instrument keypad – angular rotation, specific rotation, molar rotation, international sugar scale, user-defined scale with factor and offset. Dimensions (WxHxD): 825 x 310 x 390 mm Weight: 40 kg
