特点
| PID Lamps | FID | FPD | 易于校正 |
| Our 9.5 and 10.6 eV lamps remain the best in the business since we developed them over 30 years ago. | Our very sensitive FID has flame out sensor that will shut off the hydrogen if the flame goes out. | Our very sensitive FPD has flame out sensor that will shut off the hydrogen if the flame goes out. | 手动 |
| Display | PC | Operating system | Peak Detection & System Operation |
| Our 7'' Color VGA display (640 x 480 resolution) is easy to read. The display is a touch screen. | Embedded Pentium Computer with > 1 GByte of RAM; data storage on 1 Gbyte USB memory stick. | Windows XP® embedded stored on 2.5 GByte smart card (the PeakWorks program and all data are on the memory stick. | Controlled by our 32 bit PeakWorks software program with more than 20 years of development. |
| ADC | Autoranging | Autozero | Programmable Voltage/current output |
| Our 16 bit ADCs provide a resolution of 1 part in 64,000 and our signal algorithm minimizes noise by signal averaging in the msec range; the ADC can acquire positive or negative signals. | The 312 has 3 ranges with computer controlled autoranging- x1, x 10, x 100. | Beginning of each run. | 0-1VDC. |
| Digital outputs | Battery life | Carrier gas | Programmable setpoints |
| USB connection. | 3-4 hours; can operate off cigarette lighter adapter. | 50 liters at 1500 PSI; typical capillary column 15-20 cc/min; typical packed column 30-40 cc/min. | The low and high setpoints (depends on the options) can be customer programmed for each point and/or compound. |
