FAQ's of Digital Polarimeter Labman ADP90:
Q: How is the Digital Polarimeter Labman ADP90 calibrated?
A: The ADP90 supports both automatic and manual calibration methods. It is recommended to calibrate the device periodically or whenever measurement accuracy must be verified, ensuring consistent performance for laboratory applications.
Q: What samples can be analyzed using the Labman ADP90?
A: This polarimeter is designed for optical rotation measurement in chemical, pharmaceutical, food, and sugar industries. It can measure solutions such as sugar syrups, pharmaceuticals, and chemical substances in a 100 mm or 200 mm sample tube.
Q: When should I use the 100 mm versus the 200 mm sample tube?
A: The 100 mm and 200 mm sample tubes offer versatility depending on sample concentration and sensitivity requirements. Use the 100 mm tube for more concentrated solutions and the 200 mm tube for dilute samples needing enhanced sensitivity.
Q: Where should the ADP90 polarimeter be installed for optimal use?
A: Install the instrument in a laboratory environment with ambient temperatures between 10C and 35C and humidity below 80% RH (non-condensing). Ensure the workspace is stable and vibration-free for accurate measurements.
Q: What is the benefit of using a sodium lamp at 589 nm in this instrument?
A: The sodium lamp at 589 nm provides a stable and monochromatic light source, crucial for precise optical rotation measurements, as it minimizes wavelength-related discrepancies and enhances result reproducibility.
Q: How do I maintain and clean the sample chamber?
A: The sample chamber is made of corrosion-resistant stainless steel, allowing easy cleaning. After use, rinse the chamber and sample tubes with appropriate solvents, and dry thoroughly to avoid contamination and maintain measurement accuracy.
Q: What advantages does a digital display offer compared to analog models?
A: The large LCD digital display presents data clearly and eliminates estimation errors common with analog readings. This feature improves efficiency, reduces operator error, and supports data recording for laboratory documentation.
