History of Photoionization

In May 2011, Dr. Jack Driscoll of HNU and now with PID Analyzers received the Outstanding Achievement Award from NESACS for the development of the first handheld photoionization detector

The Model 102+ represents the fifth generation of that device



Schematic of PID


Photoionization Process

R + h = R+ + e –

Where:

R= a molecule with an IP <10.5 for the 10.6 or 11.9 for the 11.7 lamp

h = a photon with an energy >= IP of the molecule

R+ is the ion formed by the process that is collected in the ion chamber-concentration is proportional to the current produced

What is unique with the 102+

Analog output- not available with other PID’s

5 amplifiers in each head

Snap on heads with additional sensors

Best 11.7 eV lamps

Bluetooth wireless included

Low cost ppb option

ppm and ppb in same instrument

Wide ppb range- 1-60,000 ppb


Snap on Heads

Interchange PID lamp heads (9.5, 10.6, 11.7 eV) without the need for recalibration

Library for 9.5, 10.6, 11.7

>300 response factors

The best option is to have a 10.6 eV lamp with an 11.7 head to use when looking for chlorinated HC


11.7 Lamps

Customer comment ” the 11.7 lamp that I got from your competitor lasted just 5 days”

We have been making 11.7 eV lamps since 1979 and they are still better than

any others out there

Our 11.7 lamps will last for 600-700 hours of operation

Model 102 & 102+ PID’s

Two Analyzers–102 PID only

Can be upgraded

Optional 9.5 & 11.7 Snap on Heads

–102+ PID Optional ppb mode (1-60,000 ppb)

1-3 additional sensors can be added for cost of sensor at time of purchase

Sensors: CG or TCD, EC (select from > 20)

Optional 9.5 & 11.7 Snap on Heads


102+

In the 102+ amp board, there are 5 amplifiers:

–PID- high input impedence- namps

–CG, TCD, IR- Wheatstone bridge-measure diff. in resistance for CG, TCD or IR for HC, CO2 or N2O

–EC1- Biased or Unbiased

–EC2- O2 or Unbiased

–EC3- Biased or Unbiased

Dichloromethane 11.35 0.2 6.8 0.6

Pyridine 9.32 6.1 7 5

Benzene 9.25 10.0 10.0 6


Snap-On Modules

It is possible to have multiple heads for the 102+ or other models

CG, TCD & IR use the same circuit but are setup differently (current)-can have separate heads for each

Unbiased EC sensors can be interchanged by customer, recalibrated then run

Readout unit will recognize type of PID or type of WB/sensor


Applications for PID

• Safety/IH Monitoring

• Area Monitoring VOCs+ LEL +Toxics

• Leak Detection for VOCs in chemical/petrochemical plants

• Transportation- Loading/Unloading Chemicals

• Monitoring Pilot Plants

• Laboratory Monitoring

• Short term; medium term monitoring-using the sleep mode
