Some Real Applications |
Sulfur Compounds in Petroleum Gases Diesel
Diesel and gasoline Total-S <10ppM by 2005 | Sievers Chemical Luminesence Detector (SCLD) for low ppB levels
VICI-Valco PDPID ( 1-2%argon/He )
10ppB H2S, COS, 0.5ppB aromatics, 10ppB formaldehyde, methanol
permament gases PDHID (100ppB O2,N2,universal ) |
Analysis of Impurities in bev Grade CO2
H2S, benzene, acetaldehyde aromatics also MeOH at <1ppB
required VICI CO2 Analysis  | S-cpds H2S, COS plus C1-C2 S and DiS < 1ppM
requires Sulfinert deactivated columns GC sampling system
dual columns for perm gases and HCs (if required)
PDPID OK to 100ppB |
Calibration - Gas Standards : Restek gas bottles stds
mid ppM to low ppB gases and VOCs

HP5890, Agilent 6890, Shimadzu GC14/17, Varian 3700 and Standalone | - Non Destructive, high sensitivity, universal OR selective
- Selective - similar sensitivity and selectivity to ECD without radioactive foil
- Non Flame - safe for process control / industrial use
- Helium Ionisation Mode - More sensitive than FID
- Selective Ionisation He doped with Argon/Krypton/Xenon
