Nano-100 Spectrophotometer Brief introduction Direct and quick measure of DNA, RNA, cell solution concentration Only need volume 0.5 to 2 µl No need cuvette or capillary tube Wavelength range 200-800 nm Software need installed in PC
Nano-100 Specification Sample volume: 0.5~2 μl Path length: 0.2 mm (high concentration measurement) 1.0 mm (ordinary measurement) Light source: Xenon flash lamp Detector type: 3864-element linear silicon CCD array Wavelength range: 200~800 nm Wavelength accuracy: 1 nm Spectral resolution: 3 nm (FWHM at Hg 546 nm) Absorbance precision: 0.003 Abs Absorbance accuracy: 1% (0.76 at 350 nm) Absorbance range: 0.02~90(10mm equivalent) Measurement time: 5S Sample pedestal material:aluminum alloy and quartz fiber Input power: 12V DC 18W Software compatibility: Windows XP,Windows 7 (32bits)
Formation of micro volume trace,only need 0.5 µl sample Because of liquid tension, the trace sample will be hemispheric which will refract the light and let light can t go through. Make the hemispheric liquid to cylindrical by another force. 0.2-1mm height space, sample is cylindrical to enable the light go through.
Operation principle of Nano-100 Wavelength will be adjusted by optical filter, then light will go through sample and photodetector, the light will be transfer to electric signal. The absorbance difference between sample and H 2 O, compare with the absorbance of standard sample, so that we get the concentration of sample. Light Optical filter sample photodetector result Data process
Operation principle of Nano-100 Nano-100 Input optical signal Transfer to electric signal and export Data analysis Result 3864-element linear silicon CCD array, Transfer 200-800nm optical signal to electric signal.
Spectrophotometer type Ultraviolet spectrophotometer ------ 200~400nm ultraviolet light. Visible light spectrophotometer ---- 400~760nm visible light. Infrared spectrometer-- 2.5~25 μm infrared light. Nan0-100 Nan0-200 200-800nm wavelength range, can measure ultraviolet and visible light. 230nm,260nm,280nm, fixed wavelength.
