FAQs of Research Polarimeter:
Q: How do I use the Research Polarimeter to measure optical rotation?
A: Start by placing your prepared sample in the supplied 100 mm or 200 mm tube. Insert the tube into the device, focus using the coarse and fine knobs, and use the rotating stage and vernier scale to align the optics. Read the result either from the optical scale or the optional digital LCD display for high-precision optical rotation values.
Q: What benefits does the Research Polarimeter offer for laboratory analysis?
A: The polarimeter provides highly accurate optical rotation measurements (0.01 accuracy) and easy operation with ergonomic controls and robust design. Its anti-reflective optics and stable illumination ensure reproducible results, making it valuable for concentration and purity analysis in research, quality assurance, and manufacturing.
Q: When should I select LED or sodium lamp illumination?
A: Choose the built-in sodium lamp for standard polarimetric analyses, especially when working with substances requiring sodium D-line light. The LED light source is ideal for general-purpose analysis, offering longer lifespan and adjustable intensity for various sample requirements.
Q: Where can the Research Polarimeter be installed and used?
A: The device is suitable for laboratories, manufacturing quality control rooms, research institutions, and educational settings. It operates dependably within the 10C-40C temperature range and 80% relative humidity, provided the area is supplied with 220V AC power.
Q: What is the process for cleaning and maintaining the polarimeter?
A: Regularly clean optical surfaces with lens-safe materials and periodically check spare parts, such as the polarizer, analyzer, and sodium lamp. Replace worn components using included spares to maintain performance, and keep the unit protected from dust and moisture when not in use.
Q: How does the manual and digital output interface work?
A: The standard model requires manual readings from the analog scale through the eyepiece. For enhanced convenience, an optional digital output displays the measurement on an LCD, streamlining data recording and minimizing reading errors.
