Overview
The Alpha-1900 dual beam of light scanning UV-Visible Spectrophotometer is designed by LASPEC for the needs of organic chemistry, biochemistry, drug analysis, food inspection, environment protection, life sciences and other fields. The instrument uses new microcomputer technology and electronic control system to optimize the traditional optical path and structure design, while expanding new functions, ensuring the accuracy, stability and durability of the instrument.
Features
1. Stable and reliable quality: Key components (deuterium lamp, tungsten lamp, Holographic grating, Detector) are imported parts, Optical inspection mirror coated with SiO2 protective film, full sealing monochromator structure.
2. Rugged and durable: 20 mm thick base to ensure that the Optical inspection system can withstand transportation vibration.
3. Stable measurement: Double beam of light dynamic feedback proportional recording metering system to ensure Baseline stability.
4. High automation: Equipped with instrument self-diagnosis and calibration recovery functions to ensure stable operation and accurate data.
5. Functional perfection: adjustable bandwidth to adapt to different sample and test requirements.
6. Various functions: support photometric measurement, quantitative analysis, qualitative analysis, kinetic analysis, DNA/RNA and protein testing.
7. Efficient and convenient: scanning speed up to 3500nm/min, light source free debugging (socket deuterium lamp and tungsten lamp, automatic light-seeking positioning).
8. Extensible: Dedicated PC anti-control workstation or GMP function PC analyst software that can be used with USB interface.
Principle
Alpha-1900 adopts dual beam of light and CT optical path design. The instrument emits a continuous Light spectrum through Illuminant (tungsten halogen lamp and deuterium lamp), and forms monochromatic light after Holographic grating. The monochromatic light is recorded by the dynamic feedback ratio of the dual beam of light metering system. One beam passes through the sample, and the other beam is used as a reference. The Detector (imported silicon photodiode) receives and compares the light intensity signals of the two beams, thereby calculating the Absorbance, transmittance and other parameters of the sample, and performs data processing and analysis through the microcomputer system.
Applications
Organic chemistry, biochemistry, pharmaceutical analysis, food inspection, environment protection, life sciences
Standards
The data did not mention specific compliance criteria.
Steps
1. Turn it on and warm up.
2. According to the test requirements, set the test mode through the instrument or software (such as photometric measurement, quantitative analysis, qualitative scanning, kinetic analysis, etc.).
3. Place the reference solution with the sample solution.
4. Perform automatic adjustment of 100% T and 0% T (zero adjustment).
5. Start measurement, instrument automatic scanning or fixed-point detection.
6. View and process data (e.g. scaling, smoothing, filtering, peak and valley detection, etc.) through a monitor or connected PC workstation.
7. After the test is completed, turn off the instrument properly.
Notice
• The instrument should be placed on a stable, non-strong vibration surface.
Make sure the instrument is fully preheated before use to ensure stability.
• When replacing deuterium or tungsten lamps, use its socket design and automatic light-seeking positioning system, without complex Optical inspection and debugging.
• Keep Optical inspection parts clean and avoid touching the mirror directly with your hands.
• Light spectrum bandwidth is reasonably selected according to sample characteristics and test accuracy requirements.
• When performing quantitative analysis, it is necessary to correctly establish and select the standard Linear dispersion fitting method.
When connecting PC software, make sure to use dedicated interfaces and software.
• Be careful when handling, although the instrument base is strong, it should still avoid violent collisions.
