Frequently asked questions

Does the spectrophotometer have a broad wavelength range?

Yes, the Unico SpectroQuest SQ4802 offers a broad wavelength range that effectively covers the critical UV-Visible spectrum, making it suitable for a wide variety of laboratory analyses.

Key specifications for spectral performance include:

  • Wavelength Range: 190nm to 1100nm
  • Spectral Bandwidth (Slit Width): Fixed at 1.8nm
  • Accuracy: Features high wavelength accuracy of ±0.3nm and repeatability of ±0.2nm

This broad capability is supported by its Double Beam, Scanning Design, which optimizes measurement accuracy across the entire range by simultaneously analyzing the test sample and the reference.

Does the spectrophotometer use high-quality light sources?

Yes, the SpectroQuest SQ4802 utilizes a reliable dual-source system to ensure accuracy across its full operational range:

  • Deuterium Lamp: Used for measurements in the Ultraviolet (UV) spectrum.
  • Tungsten Halogen Lamp: Used for measurements in the Visible (Vis) spectrum and near-infrared.

This combination provides consistent, broad spectral coverage for accurate analysis across the full 190nm to 1100nm wavelength range.

What comprehensive analysis modes are included?

The SpectroQuest SQ4802 includes comprehensive built-in software accessible via the onboard 1/4 VGA backlit LCD screen and keypad. This allows for sophisticated analytical work directly on the stand-alone unit, making it suitable for demanding applications in pharmaceutical, biochemical, and clinical labs.

The integrated software supports several key measurement and analysis modes:

  • T/A/Conc: Measures Transmittance (T), Absorbance (A), and calculates Concentration (C).
  • Standard Curve: Used for generating and calculating calibration curves.
  • Kinetics: Essential for monitoring reaction rates over time.
  • Multi-Wavelength: Enables simultaneous measurements at multiple specified wavelengths.
  • Scanning: Provides full spectrum scanning across the 190nm to 1100nm range (up to 1000nm/min).
  • DNA/Ratio: Specialized modes for DNA and protein calculation ratios.
Does the monochromator have a precise spectral bandwidth?

Yes, the Unico SpectroQuest SQ4802 utilizes a highly precise, fixed spectral bandwidth (slit width) of 1.8nm.
