FAQs of DOUBLE BEAM SPECTROPHOMETER:
Q: How does a double beam spectrophotometer function in laboratory analysis?
A: A double beam spectrophotometer measures the intensity of light before and after it passes through a sampleusing two separate beams, one for the sample and one for reference. This setup compensates for fluctuations in light source and detector, providing more accurate and stable readings during chemical and biological analyses.
Q: What are the key advantages of using both halogen and deuterium lamps in this spectrophotometer?
A: The use of both halogen and deuterium lamps enables measurement across a wide wavelength range including UV and visible light. This dual-lamp configuration supports diverse applications, from nucleic acid and protein quantification to color analysis, broadening the instruments usability in different research fields.
Q: When should a laboratory choose a double beam spectrophotometer over a single beam model?
A: A laboratory should select a double beam spectrophotometer when consistent, high-precision measurements are crucial, particularly for long-duration or repetitive analyses. The double beam design minimizes signal drift caused by lamp or detector instability, delivering more reliable results over time compared to single beam models.
Q: Where is data from the double beam spectrophotometer stored and how is it transferred?
A: Data from the double beam spectrophotometer can be stored locally within the instrument or transferred via USB or RS232 interfaces to computers running compatible Windows-based software, making analysis, record-keeping, and reporting efficient and secure.
Q: What is the significance of the instruments 2 nm spectral bandwidth and low stray light specification?
A: The 2 nm spectral bandwidth enables precise wavelength selection, improving measurement resolution and sensitivity. With stray light limited to 0.05% T, the spectrophotometer provides accurate readings even at low absorption levels, which is critical for reliable research conclusions.
Q: How energy efficient is this spectrophotometer for daily laboratory use?
A: Consuming just 70 W of power and operating on a voltage range of 110240 V, this instrument is energy efficient and suitable for continuous laboratory use with minimal electricity costs.
