Detail UV Spectrophotometers & Analytical Chemistry

In molecular biology and analytical chemistry, the device knows as a UV spectrophotometer is essential and can be a valuable resource for any chemistry student and indeed, for practitioners, laboratory scientists, teachers, and professors-anyone who needs to know something about how laboratory analyses are carried out. Common requirements for uv spectromphotometer are Wavelength Range: 190 – 1100 nm. Spectral Bandwidth: 1.8 nm / 0.5, 1, 2, 5 nm. Monochromator: Single beam Littrow type, grating 1200 lines/ mm. Wavelength Accuracy: ± 0.3 nm. Wavelength Repeatability: ± 0.2 nm. Wavelength Calibration: automatic at start. Light Source: Tungsten Halogen/ Deuterium Lamp. Detector: Solid Silicon Photodiode. Photometric Readout: 1/ 4 VGA 320X240 pixels backlit LCD. Photometric Range: 0 – 200% T -0.3 – 3.0A 0 – 9999C. Photometric Accuracy: ± 0.3% T. Zero Drift: < 0.002A per hour after warm-up. Baseline Flatness: ± 0.004A. Stability: 0.002A/ h at 500 nm. Stray Light: < 0.15% T. Scanning Speed: Hi, Med., Low. Max. 1000 nm/ min. Standard Sample Holder: 8-position Cell Holder. Analogue/ Digital Output: Digital, RS232 Serial, Centronics Parallel. And the minimum number of this user is more than 700 million. For this amount of people in UV spectrophotometer marketing, it has got a specification. If you want to cover an aide range of area for your analysis, you have to use more than one detector in you UV spectrophotometer machine. The manufacturer who is using this technology is in the high position of UV spectrophotometer marketing. They are earning a huge sum of money every year. A good number of UV spectrophotometer often we are using with the photomultiplier tube today. It is good for the measurement of any radiation or wavelength. This is the process to activate the device for covering both the UV and visible area. In the distance of 1, 100 nm, it can cover the infrared area specifically. The manufacturers of UV spectrophotometer are using lead sulfide layer with the detector to make the machine more active that can realize any type of radiation and wavelength. There are many manufacturing companies of UV spectrophotometers who are using detectors made by gallium arsenide, indium and so on. But it is a main fact that this detector cans only works on 1800 nm. But it will give you the best resolution and different result than the others. This wills enable you to decrease the PMT technology in the sector of UV spectrophotometer. Some good reputed company is also using these three detectors in their latest products. And there are varying price difference for this technology. It has increase the price of UV spectrophotometer. UV spectrophotometer is a type of electronic device that depend on other electronic applications. It is used on the technology of fiber optics, semiconductors and materials in photonics. This technology is using day by day in the field of biotechnology and pharmaceuticals.
