| Characteristics |
|
Model 970CRT spectrofluorophotometer is the high level spectrofIuorophotometer in our country. The current advanced computer software and hardware of PC is adopted in this instrument. it has the best property of qualitative and quantitative testing, and is widely used for microanalysis and trace analysis and test in the case of chemica1 experiment, medicinal inspection, environmental protection, petroleum industry, chemical industry, medical hygiene. foodstuff nutrition and so on.
High sensitivity, high Signal/noise ratio, S/N can reach over 100. The technic of light source monitoring is adopted. the test resu1t is stable.. use the rapid 20 digits A/D transformation technic, its dynamic measuring range is wide, and the linearity is better.
Use the advanced Chinese Windows 98 software. The function of data atlas processing is powerful and the operation is easy and convenient. Use the Standard PC computer as the hard ware circumstance, The failure rate of instrument is low. reliability is better. |
| Function |
|
Windows 98 station: Windows with Chinese dialogue is used entirely in the station. It can control the main machine directly and proceed the
data processing. A series of operation of scan testing, data analyzing, table making and recording can be easily compl9ted by pressing the
mouse button.
The 20 bits high speed A/D transformer is used, the dynamical range is large .the mini changes of sample can be tested rapidly and exactly. |
| Function of software |
|
Filtering: 1~4 orders of derivative, peak retrieving, peak area calculating, continuous scan testing, quantitative sample analyzing, plotting the standard curve (1~3 times), finding the concentration of test sample according to the standard curve, at1as saving and loading, atlas window treating, automatic testing the ratio of S/N and so on. |
