1. The SISC Chromatography data system uses high quality 24-bit ADC (analog digital conversion) card. The range of input voltage is +/- 1.250 V with a 20 points/sec. data collecting rate. The minimum display scale on monitor is 0.1 uV with a sensitivity of +/- 2 uV. The real resolution is over 1,000,000. The linear range error is within 0.002%.

2. The interface card between the computer and the instrument equipped with independent ADC card for each individual channel. This special design of SISC Chromatography data system resolved the sensitivity reduction issue resulted from the signal interference by applying a shared ADC card for several channels.
 

The system runs maximum in 4 GC detectors simultaneously with a maximum data collecting rate of 20 points/sec. To add another PCI 24 bit ADC interface allows the data station to collect 100 data points per second for the fast GC application.

 
3. Eight independent voltage settings including dipolar, +/- 2.5V, +/- 1.25V, +/- 620mV, +/- 310mV, +/- 160mV, +/- 80mV, +/- 40mV and +/- 20mV. The benefit of the design is that a system can handle different instrument types to meet the various requirements of signal/noise ratio.

4. The multi-task design allows the system to display 4 independent windows simultaneously. Each window has its own initial setting on data collecting parameters, instrument condition information, chromatogram integration parameters and report printing form. It also allows the user to adjust the X, Y scale, character size of the text and the color setting of the chromatogram in the window.

5. The data system is capable to collect a maximum of 1000 samples with an auto-sampler for each channel. It provides a smart program to assign a sequential sample I.D automatically. The sample description and the sample concentration calculation module were also designed in the system with a spreadsheet format for repeated uses.

6. The ADC interface card of the system has been calibrated by a standardized NTIS calibration system. SISC provides a calibration report for our client in order to fulfill the requirement of a chromatogram data system validation program.

7. The data collecting rate can be set between 30 to 0.1 points per second (100 poinrs for PCI interface card) in order to meet the various analytical requirements of GC (including capillary and packed columns) HPLC, IC, Capillary electrophoresis and GPC applications.

8. In order to meet the quality assurance requirements of GLP, the data system is designed to set the integrating, reporting, instrument condition parameters independently with different detectors. In addition, the raw data including injection time, calibration curve, etc. will be stored at the end of a sample run to avoid any tampering of the original data
