Specifications

Detectors: Species measured: Detection Limit:
Photoionization detector (PID), Flame ionization detector (FID), Thermal conductivity detector (TCD), Flame photometric detector (FPD), Far UV absorbance (FUV) detector, Catalytic combustion detector (CCD) PID & FID: Organics (VOCs by PID or FID) and inorganic species (H2S, NH3, AsH3… ) that can be ionized by the PID lamp (9.5, 10.6 or 11.7 eV)
TCD: Universal detector- fixed gases (O2, N2, CO…), organic and inorganic compounds, very sensitive for H2, He, Xe

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
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.
Oven
Size:
Typical column diameter: 3.5''
Temperature range:
Battery: 25-50 Degrees Celcius
External power: 25-100 Degrees Celcius
