FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The UV-Vis-NIR spectrophotometer is used in chemistry, material science, pharmaceutical, environmental and food laboratories for qualitative and quantitative analysis across ultraviolet, visible and near-infrared wavelengths. It supports compound identification by spectral scanning, concentration measurement by Beer-Lambert law, material characterization by NIR reflectance, color measurement and kinetic reaction monitoring. The extended NIR range enables analysis of organic functional groups, polymer characterization and agricultural product quality assessment without complex sample preparation.
Q2: What standards does the instrument comply with?
A: The instrument supports analytical methods referenced in USP, EP and ChP monographs, ISO 15529 for NIR transmittance, ASTM E169 for UV-Vis quantitative analysis, and relevant GB/T standards for spectrophotometry. The hardware complies with IEC 61010 laboratory safety standards. Wavelength and absorbance accuracy should be verified with certified reference materials.
Q3: What is the warranty period for the whole machine and key components?
A: The whole spectrophotometer is covered by a 12-month warranty. The optical system, detector, light source and controller are covered, while lamps, cuvettes and calibration standards are consumables excluded from warranty. Extended warranty and service contracts are available for this high-value system.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained analysts familiar with spectrophotometric principles and method development. We provide structured operator training, application support and method consultation. Routine use by trained operators is supported by software wizards and standard operating procedures.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Wavelength and absorbance calibration with certified reference materials should be performed every 6-12 months for accredited laboratories. Routine verification with a reference standard before each analytical batch is recommended. Lamp replacement and optical alignment should follow the manufacturer schedule.
Q7: Are supporting consumables universal?
A: Lamps, cuvettes and calibration standards are available from multiple qualified suppliers, though original lamps and optics are recommended for optimal performance. NIR accessories such as integrating spheres may be model-specific. Long-term consumable cost is moderate.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes detector type, wavelength range, resolution, sample compartment accessories and software modules. Custom orders require application discussion and extend lead-time. Users should define sample types, measurement modes and sensitivity requirements before configuration.
Q9: Does the purchase include on-site installation and commissioning service?
A: Yes, advanced spectrophotometers include on-site installation, commissioning and operator training by a certified application specialist. Site preparation guidance is provided before delivery.
Q10: What types of samples are compatible with this equipment?
A: The instrument analyzes liquid, solid and powder samples within the wavelength and absorbance range. Samples must be properly prepared and homogeneous for accurate results. Highly scattering samples may require integrating sphere accessories. Corrosive or abrasive samples can damage cuvettes and optics and require special handling.
