Gas Type Analysed with Chromatography Gas and GC Detachment Role in Industrial Gas Composition Analysis
Gas Type Analysed with Chromatography Gas
Chromatography gas is used to analyze different classes of volatile gas, both hydrocarbons, permanent gases, as well as trace compounds, which each has different technical and business implications.
Analysis using Kromatography gas on PT. Hidea Inti Daya Laboratories in Attack
1. Hydrocarbons gas
General components:
- Methane
- Methane, Propana, butane (C-C-mez)
- Pentana, Heksana (C - C)
- Heavy hydrocarbons (C7-C12 +)
Role in gas analysis:
- Specify Taylor (HHV / LHV) value
- Burning stability evaluation
- Identification risk condensation and liquid dropout
Industrial implications:
- Accurate determines the price of gas
- Conducting contract specs
- Optimize burning efficiency
2. Permanent Gas (Non- Hydrocarbons)
General components:
- Carbon dioxide.
- Nitrogen (N spans)
- Oxygen
- Hydrogen
Role in gas analysis:
- Judging the quality of fuel
- Detect air leaks or contamination
- Control process refinery and plant
Industrial implications:
- Quality penalty prevention
- Safety process
- Operation stability
3. Tracking gas and Contaminan
General components:
- Sulfur Compound (H HS, COS, Capture)
- Organic halogen compound
- BTEX and VOC
- Inert gas (He, Ar)
Role in gas analysis:
- Safety of work and environment
- Corrosion and fouling prevention
- Monitoring emissions and regulation compliance
Industrial implications:
- Asset protection
- Regulation regulation
- Downtime risk reduction
GC detector role in Gas Composition Analysis
The GC detector selection determines which type of gas can be detected, sensitivity, and analytical reliability. There is not one detector suitable for all applications; therefore, the selection has to be adjusted to the compound class of the target and industrial needs.
Thermal Conductivation Detector (TCD)
Main role:
- Permanent gas detection and simple gas mix
- total gas composition analysis
Character:
- universal properties
- Non- destructive
- Middle sensitivity (ppm)
General applications:
- Natural gas
- Gas refinery
- Headspace analysis
Flame Ionization Detector (FID)
Main role:
- Hydrocarbon detection from C1 to heavy fractions
Character:
- Very sensitive to carbon-based compounds
- Linear range wide
- Not responding to inorganic gas
General applications:
- Hydrocarbons profile
- Fuel gas
- VOC industry
Selective detectors for Non- Hydrocarbons and Trace Gas
Electron Capture Detector (ECD)
- Specific for halogen compounds
- Very high sensitivity (sub-ppb)
- Used in environmental and contaminant analysis
Flame Photometric Detector (FPD) / Sulfur Chemiluminescence Detector (SCD)
- Selective for sulfur and phosphorus
- Used to control quality and safety
Nitrogen Phosphorus Detector (NPD)
- Selective for nitrogen and phosphorus compounds
- Used for amina and organofosfat
Advanced Detectors for Trace Analysis
- GC-MS / GC-MS / MS
High structural identification and sensitivity (ppb-ppt) - PID (Photoonization Detector)
Monitoring BTEX and aromatic VOC without flames - DID (Discharge Ionization Detector)
Alternate non-destructive for permanent gas
GC Selection Decision Matrix
| Gas / Needs | TCD | FID | ECD | FPD / SCD | GC-MS |
|---|---|---|---|---|---|
| Permanent gas | ✔️ | ❌ | ❌ | ❌ | ✔️ |
| Hydrocarbons | ✔️ | ✔️ | ❌ | ❌ | ✔️ |
| Hydrocarbon heavy | ◻️ | ✔️ | ❌ | ❌ | ✔️ |
| Allegen organic | ❌ | ❌ | ✔️ | ❌ | ✔️ |
| Sulfur | ❌ | ◻️ | ❌ | ✔️ | ✔️ |
| Trace gas (ppb / ppt) | ❌ | ❌ | ✔️ | ✔️ | ✔️ |
➡️ Industrial's best practice:
TCD + FID combination for primary analysis, plus selective detectors or GC-MS for trace and confirmation needs.
| Symbol | Meaning |
|---|---|
| ✔️ | Very suitable / recommended |
| ◻️ | It can be used with limitations |
| ❌ | Unmatched / unusable |
Technical Cover
The precise understanding of the types of gases analyzed and the role of each GC detector is the key to generating accurate, relevant, relevant gas composition data. This approach allows industry to manage the quality of gas effectively, as well as support operational decisions, safety and business.
