Overview
Alpha-1502 UV-Visible Spectrophotometer is an analytical instrument designed and produced by LASPEC. The instrument has the advantages of high accuracy, good stability and strong durability, and is widely used in basic testing needs in food, environment protection, cement manufacturing, analysis, teaching, scientific research and other fields.
Features
1. Powerful instrument automatic control system: can automatically set the wavelength, automatically adjust 0% T, 100% T, support T/A error-free conversion and A, T, C direct reading function, with highly automated instrument self-diagnosis and correction recovery function.
2. Excellent instrument performance: using new microcomputer technology and electronic control system, optimizing the light path and structure design, using imported brand Detector and grating, effectively improving stray light control, luminosity accuracy and stability.
3. Simple operation and strong scalability: The function menu is equipped with operation prompts, which is easy to use. Support quantitative analysis, kinetic testing, large memory capacity, can store 200 standard Linear dispersion and 500 sets of experimental data. Optional built-in micro thermal printer, and support for connecting a dedicated PC anti-control workstation via USB.
4. Fully functional: In addition to photometric measurement, it also supports quantitative analysis, and can automatically establish standard Linear dispersion (support first-order and first-order zero-crossing linear regression). Standard Linear dispersion can be stored and used for subsequent test calls.
Principle
The instrument adopts a single beam of light and a self-aligning Optical inspection system. The light emitted by the Illuminant is separated by a laser holographic Diffraction grating of 1200 lines/mm to form a monochromatic light of a specific wavelength. The monochromatic light passes through the sample, is received by the Detector and converted into an electrical signal. After processing by the microcomputer system, the measurement results are directly read out in the form of light transmitance (T), Absorbance (A) or concentration (C) on the display.
Applications
Food, environment protection, cement manufacturing, analysis, teaching, research
Steps
1. Turn it on and warm up.
2. According to the test requirements, set the wavelength through the instrument's automatic control system.
3. Put in the blank sample and perform the automatic adjustment of 100% T and 0% T.
4. Put in the sample to be tested and perform photometric measurement.
5. If quantitative analysis is required, the corresponding function can be selected to automatically establish or call the stored standard Linear dispersion for testing.
6. Test results can be read through a monitor, or printed through an optional printer, or data can be transferred via a USB connection to a PC workstation.
Notice
The instrument should be placed on a stable and clean workbench to avoid vibration and direct exposure to strong light.
* Full preheating is required after startup to ensure Illuminant stability and measurement accuracy.
* When using the Cuvette, make sure its transparent surface is clean and free of fingerprints, stains or scratches.
When automatically adjusting 100% T and 0% T, make sure that the Cuvette position is correct and the blank sample meets the requirements.
* When storing standard Linear dispersions and data, be careful not to exceed the instrument's maximum storage capacity (200 Linear dispersions and 500 sets of data).
When connecting a PC workstation or using USB transfer, make sure to use dedicated software and the correct connection method.
* Periodic instrument maintenance and performance checks, using the instrument's self-diagnosis and correction recovery function when necessary.
