PORTABLE GC ( Gas Chromatography)

PID Analyzers offers a new lightweight portable GC for environmental, quality control, natural gas... applications. The base Model 312 comes with syringe injection, oven, power supplies & Pentium PC with Windows XP ( embedded) and PeakWorks chromatography software in a rugged plastic case. Specifications Detectors: Photoionization detector ( PID) , Flame ionization detector ( FID) , Thermal conductivity detector ( TCD) , Flame photometric detector ( FPD) , Far UV absorbance ( FUV) detector, Catalytic combustion detector ( CCD) Species measured: 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 FPD: Selective response for S or P compounds Far UV: Nearly universal response for organic and inorganic compounds CCD: Combustible compounds such as hydrocarbons Detection Limit: PID- 0.5 ppb benzene FID- 50 ppb benzene TCD- H2- 10 ppm; O2 150 ppm Linear Dynamic Range: PID- 108 FID- 2 x 106 TCD- 2 x 104 FPD- S- 103; P 105 Far UV- 106 CCD- 5 x 104 Sensor( s) : 1 or 2 detectors Precision: + / - 1-2% of reading Response time: : Depends on retention times Sample flow rate: > 0.5 LPM Injection: On-column syringe injection or automatic with 6 port gas valve ( optional) Span Drift: < 1% over 24 hours Zero Drift: NA- autozero on each run Power consumption: 1 GByte of RAM; data storage on 1 Gbyte USB memory stick Operating system Windows XP® embedded stored on 2.5 GByte smart card ( the PeakWorks program and all data are on the memory stick Peak Detection & System Operation: Controlled by our 32 bit PeakWorks software program with more than 20 years of development ADC 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 Autoranging The 312 has 3 ranges with computer controlled autoranging- x1, x 10, x 100 Autozero Beginning of each run Programmable Voltage/ current output 0-1VDC Digital outputs USB connection Battery life 3-4 hours; can operate off cigarette lighter adapter Carrier gas 50 liters at 1500 PSI; typical capillary column 15-20 cc/ min; typical packed column 30-40 cc/ min Oven Size: Typical column diameter: 3.5” Temperatur range: Battery: 25-50 Degrees Celcius External power: 25-100 Degrees Celcius Programmable setpoints The low and high setpoints ( depends on the options) can be customer programmed for each point and/ or compound
