FAQs of Advance UV Visible Spectrophotometer:
Q: How does the Advance UV Visible Spectrophotometer ensure precise wavelength settings during analysis?
A: The device supports wavelength accuracy of 0.5 nm, allowing for exact wavelength selection using its semi-automatic controls. Users can set wavelengths within the 190 nm to 1100 nm range, with auto zero adjustment assisting in precise calibration before measurements.
Q: What types of samples and laboratory analyses are suitable for this spectrophotometer?
A: This spectrophotometer is designed for both quantitative and qualitative measurements of liquid samples ranging from 2 ml to 10 ml. It is effective in laboratory analysis for research, pharmaceutical testing, and industrial quality control, accommodating a broad spectrum of compounds absorbing in the UV and visible regions.
Q: When is it appropriate to use the selectable scan speed feature?
A: Selectable scan speeds (Fast/Medium/Slow) allow users to optimize analysis depending on the urgency and nature of the sample. Rapid scans are suitable for routine measurements, while slower speeds provide more detailed spectral data for intricate analyses.
Q: Where can data from the spectrophotometer be exported and stored?
A: Data can be exported via USB or RS232 interface, enabling integration with laboratory computers and specialized data management systems. This facilitates easy storage, analysis, and sharing of results for reporting or further research.
Q: What process should be followed to achieve accurate baseline stability and repeatability?
A: Prior to sample measurement, baseline flatness (0.002A from 200 to 1000 nm) should be validated by running a blank. The auto zero adjustment helps maintain this stability, while photometric repeatability of 0.15% T ensures consistent results across multiple measurements.
Q: How does this spectrophotometer benefit laboratory workflows and analysis reliability?
A: Offering features such as highly accurate readings, user-friendly digital display, and robust construction, the Advance UV Visible Spectrophotometer streamlines analysis processes, reduces manual errors, and enables reproducible, trustworthy outcomes for researchers and quality specialists.
