Introduction
A UV analyzer is an instrument used for the observation and the analysis of the samples under the ultraviolet (UV) light, and it is used in the chemistry, the biology, the pharmaceutical, the forensic, and the many other applications. The UV analyzer emits the ultraviolet light at the specified wavelengths, such as 254 and 365 nanometers, and it is used for the observation of the samples, such as the thin layer chromatography (TLC) plates, the fluorescent materials, and the documents, with the fluorescence or the absorption observed; the UV analyzer consists of the UV lamps, a viewing cabinet or the chamber, and the controls, and it provides the UV illumination, with features such as the adjustable wavelengths; the UV analyzer is used for the examination of the TLC plates, for the observation of the fluorescent compounds, for the inspection of the documents and the banknotes, for the forensic examination, for the quality control, and for many other applications, and it is available in various configurations; the UV analyzer is an essential instrument for the UV observation. UV analyzers are used in the chemistry laboratories, in the biology laboratories, in the pharmaceutical industry, in the forensic, and for many other applications. With their UV illumination, UV analyzers are essential for the observation of the fluorescent samples.

FAQ
Q1: What testing scenarios is this analyzer mainly applied to?
A: The UV analyzer is used in chemical analysis, biological research, pharmaceutical quality control, environmental monitoring, food testing and educational laboratories to measure ultraviolet absorbance of samples for quantitative analysis, concentration determination and purity assessment. It supports nucleic acid and protein quantification in molecular biology, pharmaceutical content and impurity testing, environmental pollutant analysis, food additive and contaminant testing, chemical compound concentration measurement, and educational UV spectroscopy demonstrations. The compact, user-friendly design provides fast absorbance measurement at fixed or selectable UV wavelengths without the complexity of a full scanning spectrophotometer. It is essential for laboratories requiring routine UV absorbance measurement for quantitative analysis, concentration determination, purity assessment and quality control in chemical, biological, pharmaceutical, environmental and food applications, where rapid, reliable UV measurement is needed for sample analysis, experimental work and quality assurance without the need for full spectral scanning capabilities.
Q2: What standards does the analyzer comply with?
A: The UV analyzer supports methods referenced in USP, EP and ChP monographs, ASTM and ISO standards for specific analytes, and relevant GB/T standards. The hardware complies with IEC 61010 laboratory safety standards. Wavelength and absorbance accuracy should be verified with certified reference materials for regulated applications.
Q3: What is the warranty period for the whole machine and key components?
A: The whole analyzer is covered by a 12-month warranty. The light source, detector, optics and controller are covered, while lamps, cuvettes and calibration standards are consumables excluded from warranty. Damage from improper use or unauthorized repair is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires basic training in UV absorbance measurement and sample handling. We provide an operation manual and remote guidance. Proper wavelength selection, blank correction, sample handling and result calculation are important for accurate quantitative analysis.
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 recommended every 6-12 months. Routine verification before each analytical batch for regulated work. Lamp replacement follows the manufacturer schedule or when intensity drops. Optical surfaces cleaned periodically.
Q7: Are supporting consumables universal?
A: Lamps, cuvettes and calibration standards are available from multiple qualified suppliers. Long-term consumable cost is moderate depending on usage and lamp type.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes wavelength configuration, measurement range, sample compartment accessories and display features. Additional cuvettes, standards and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the analyzer and accessories with an operation manual. On-site installation and training are not included for standard orders but can be arranged for laboratory setup projects. Remote guidance is provided.
Q10: What types of samples are compatible with this equipment?
A: The UV analyzer measures absorbance of liquid samples within the wavelength and absorbance range. Samples must be clear and homogeneous; turbid samples cause scattering errors. Highly corrosive samples require compatible cuvette material. Very high absorbance samples should be diluted to the linear range. Users should select the appropriate wavelength for the analyte, perform proper blank correction, use matched UV-transparent cuvettes (quartz for far UV), allow lamp warm-up before measurement, and follow calibration and verification procedures to maintain measurement accuracy and traceability for quantitative UV analysis.
