Detailed Description of N2000 Workstation
1、 Features after software upgrade 1. The algorithm of data has been changed to make online preview and offline preview of data *, avoiding the question of the industry competent department on the authenticity of data.
2. The printing function is powerful, compatible with various printers, and the continuous printing effect is good.
3. "Sample injection time" is clearly marked in the report to avoid users' debate on the test time.
4. In the process of sampling or at the end of sampling, a dialog box similar to Access navigation at address, Read of address 0000028 will not pop up, so that the sampling results cannot be saved, which costs much time.
5. To combat rampant piracy in the market and protect the interests of users, N2000 Chromatographic workstation Version 6.1 adopts technology.
2、 Acquisition card linearity:
N2000 Chromatographic workstation Chromatographic signal acquisition card is the bridge between chromatograph and computer. The acquisition card itself contains a single chip processor system, which is placed separately in a shielded case, and has an independent external power supply. * 16/24 (optional) bits of high-precision A/D (analog digital) conversion chip (including PGA programmable amplification, Gaussian low-pass filtering, zero point, full scale, background, misalignment and other automatic correction functions), resolution: full range+- 1um (to ensure full range linearity)
(1) Automatic zero calibration function for temperature drift: With the continuous development of computer technology, the chip integration is increasing and the operation speed is accelerating, which makes the temperature of the computer case become higher and higher. The automatic zero calibration function for temperature drift ensures that the acquisition card is not affected by the outside world and the temperature change of the acquisition card itself, and ensures the reproducibility of chromatographic analysis.
(2) Data error automatic calibration function: use dynamic memory to continuously record and accumulate error data, and automatically calibrate during data acquisition to minimize the impact of errors
N2000 Hardware: It can be connected to general chromatographic instruments including Shimadzu, Agilent, Waters, etc., and a universal chromatographic data workstation.
3、 Technical indicators:
（1） Software:
1. Automatically identify solvent peak, trailing peak, sawtooth peak, front and rear shoulder peak.
2. Automatically adjust parameters (peak width, slope) during analysis.
3. Automatic tracking of baseline and automatic classification of chromatographic peak types; Peak rise and fall points.
4. Powerful manual integration function, peak addition and subtraction, peak baseline adjustment, and cutting mode adjustment.
5. The integrated sensitivity is 1 μ V · s, the zui small resolution is 0.1 μ V, and the zui small peak width is 0.1 s.
6. Data results can be shared with Microsoft Excel, Word and other software; The data spectrum can be compared with Photoshop
CorelDRAW and other image software sharing.
7. Data re analysis function, archiving.
8. Quantitative calculation method: normalization method, correction normalization method, internal standard method, grouping method, external standard method, index method.
（2） Hardware:
1. Dual channel, external type.
2. Output - 5mv-1.7v.
3. The input impedance is greater than 10 megohm.
4. Dynamic range: 107, linearity: ± 0.1%.
5. The sampling frequency is 10, 25, 50 times/second.
6. RS232 communication mode, key remote control, keyboard shortcut or mouse menu |
