FAQs of Double Beam UV Visible Spectrophotometer:

Q: How is the Double Beam UV Visible Spectrophotometer used for spectrophotometric analysis?

A: The spectrophotometer utilizes a double beam optical system with deuterium and tungsten halogen lamps to analyze samples over 190 nm to 1100 nm. Users place samples in the 4-position auto-changer cuvette holder, select desired measurement mode and scan speed, then view results on the large LCD display or export data via USB or RS232.

Q: What are the key benefits of dual beam design in this spectrophotometer?

A: The dual beam design enhances measurement accuracy by simultaneously comparing sample and reference signals, reducing noise and drift. This results in more reliable quantitative and qualitative data, especially helpful in sensitive assays or routine laboratory applications.

Q: When should I use the different operating modes available on the spectrophotometer?

A: Choose "Spectrum" mode to record absorbance across a range of wavelengths, "Quantitative" mode for concentration determinations, "Kinetics" to monitor reaction progress, and "Multi-wavelength" for simultaneous reading at several set wavelengths. Select based on your specific analytical requirements.

Q: Where can the UVS-2002DB spectrophotometer be installed for optimal use?

A: It is suitable for laboratories in universities, research institutes, pharmaceutical industries, and manufacturing facilities. Ensure installation in an environment with ambient temperature (5C45C), humidity 85% RH, and stable AC mains power for best results.

Q: What is the process for sample preparation and measurement using this equipment?

A: Prepare samples using standard cuvettes (2 ml to 100 ml), ensuring cleanliness and proper volume. Insert the cuvette into the auto-changer, configure measurement settings, perform auto-calibration, and initiate the analysis. The system provides rapid, stable results with selectable scanning speeds.

Q: How does auto-calibration impact instrument accuracy and reliability?

A: Auto-calibration adjusts optical and electronic components automatically, ensuring consistent wavelength accuracy (0.5 nm) and minimal drift or baseline deviation. This reduces manual intervention and maintains high analytical reliability over time.
