简单介绍
High speed F96S fluorescence spectrophotometer for determination from ultraviolet light to visible light, single engine, 2 modes of online support, provide the fluorescence intensity measurement, dire
产品描述
You can choose the fluorescence intensity and the light intensity of the 2 modes of operation, the fluorescence intensity can be carried out under the model of quantitative analysis and determination of fluorescence spectra, fluorescence kinetics.
By the cold light source with high reliability, compared with the commonly used thermal source with low background, low power consumption, low temperature, long service life, high strength advantages, avoid heat pollution, more energy saving and environmental protection advantages.
B on the excitation wavelength of 365nm water Raman peak SNR is greater than or equal to 90 (P-P), high sensitivity is suitable for measuring ultra low concentration sample.
It provides 10 tranches of emission spectrum sweep speed, including high speed and low noise and fine scanning scanning. The ultrafast 30000nm/min scan, can be completed within one second full spectrum scanning, and intelligent pre scanning function, can quickly display the spectral information of unknown samples, automatically exclude other scattering peaks and peak frequency, the optimal measurement parameters, positioning fluorescence emission peak.
It supports 2 modes, single line, provide the fluorescence intensity measurement, direct reading, auto zero, automatic background subtraction and other functions use machine microcomputer system of single state, online through the USB2.0 interface using qualitative / quantitative software for instrument control and data collection and analysis.
By the quantitative analysis with the fluorescence value of the normalized function, can eliminate the different fluorescence photometer between fluorescence values cannot be compared, the unified evaluation of students' experimental report of convenient teaching in Colleges and universities.
Function. The qualitative / quantitative software rich emission wavelength scanning map, zoom menu can provide multi map comparison, map operation, peak detection, peak area calculation and 1-4 derivative spectrum function; quantitative test menu can detect sample concentration using the standard curve method and the method of undetermined coefficients, a linear regression, two order or order three order linear fitting, and can customize the concentration unit.
. A variety of measurement accessories, including single hole color plate seat, multipurpose fluorescent sample holder and 200 L microcentrifuge tube fluorescence measurement and capillary micro sample frame, fluorescent samples semi automatic sampling, single hole cuvette adapter, membranous
sample frame, powder sample frame and sheath type cuvette etc. micro sample as low as 5 l can be easily measured, the high concentration solid fluorescence detection, fluorescence detection is also suitable, can meet a variety of requirements.
Very little and dainty models can save a lot of desktop space
