Features
| PID Lamps | FID | FPD | Ease of calibration |
| 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. | Manual. |
| Display | PC | Operating system | Peak Detection & System Operation |
| NA - Requires external PC (not included). | Requires Pentium Computer (not provided) with > 1 GByte of RAM and hard drive > 40 Gbyte. | Windows XP® (not provided). | 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- Uses USB connection to external PC. | The 322 has 3 ranges with computer controlled autoranging- x1, x 10, x 100. | Beginning of each run. | 0-1VDC. |
| Digital outputs | Oven | ||
| USB connection. | Size: 7'' x 7'' Typical column diameter: 3.5'' Temperature range: Isothermal: 25-150 Degrees Celcius Temperature programmed: 25-200 Degrees Celcius. |
