MAX300-TGM Toxic Gas Monitoring System
MAX300-TGM Toxic Gas Monitoring System
The EXTREL™ MAX300-TGM™ Toxic Gas Monitoring System uses quadrupole mass spectrometry to continuously detect and quantify hazardous gases across industrial facilities.
Unlike traditional distributed single-gas detectors, one MAX300-TGM can simultaneously monitor 15+ gases across up to 46 sampling points from a centralized analyzer. With analysis speeds of approximately 0.4 seconds per chemical and gas clearing times of less than 3 seconds, the system provides rapid toxic gas detection for life safety, worker protection, process protection, and environmental monitoring.

What Is the MAX300-TGM?
The MAX300-TGM is a centralized, real-time toxic gas monitoring system that uses quadrupole mass spectrometry to detect multiple hazardous gases across multiple facility locations.
Rather than installing and maintaining individual single-gas sensors at every monitoring point, the MAX300-TGM can analyze more than 15 gases from up to 46 sample locations using one centralized analytical system. Typical monitoring locations include gas cabinets, valve manifold boxes, process tools, exhaust ducts, ambient air, chemical storage rooms, equipment enclosures, and operator breathing zones

Why Centralized Toxic Gas Monitoring?
Traditional toxic gas detection often relies on individual sensors distributed throughout a facility. Each sensor may require its own calibration, maintenance, replacement parts, and service schedule.
The MAX300-TGM takes a different approach.
Multiple Locations → Centralized MAX300-TGM → Multiple Gas Measurements → Alarm / Facility Safety System
One analyzer continuously samples multiple facility locations and analyzes them using quadrupole mass spectrometry.
This centralized approach can help reduce:
Sensor count | Calibration effort | Maintenance labor | Spare parts | System complexity | Lifecycle costs
Fast Response for Life Safety
When a Hazardous Gas Is Released, Every Second Matters.
The MAX300-TGM is designed for rapid detection and alarm management with:
- ~0.4-second analysis per chemical
- <3-second gas clearing
- Continuous monitoring sequences
- Automatic revisit of alarmed locations
- Intelligent alarm prioritization
- Two-level alarm management
- Facility safety system integration

4 Key Customer Challenges
1. Detecting a Toxic Gas Release Fast Enough
“Will we detect a hazardous gas release before it puts people or production at risk?”
Hazardous gas releases can occur unexpectedly around gas cabinets, process tools, chemical storage areas, valve manifold boxes, and exhausted enclosures. Delayed detection can increase risk to personnel, equipment, and production.
The MAX300-TGM continuously monitors toxic gases with analysis speeds of approximately 0.4 seconds per chemical, gas clearing times under 3 seconds, automatic revisit of alarmed locations, and two-level alarm management.
2. Managing Too Many Single-Gas Sensors
“How many individual sensors do we really want to install, calibrate, maintain, and replace?”
Traditional monitoring architectures may require numerous distributed sensors to cover different gases and locations. As facilities expand, maintenance requirements, spare-parts inventory, calibration effort, and lifecycle costs can increase.
One centralized MAX300-TGM can monitor 15+ gases across up to 46 sample points, reducing dependence on large networks of individual single-gas sensors.
This may be the product’s strongest commercial differentiator.
3. False Alarms & Gas Interferences
“Can we trust the alarm or are we reacting to another interference?”
In complex industrial environments, gas interferences can make reliable identification difficult. False alarms can trigger unnecessary responses and potentially interrupt production.
Quadrupole mass spectrometry provides multicomponent gas identification, while the MAX300-TGM is designed for interference-free gas identification and intelligent alarm prioritization, helping facilities improve confidence in toxic gas alarms.
4. Scaling Facility-Wide Gas Monitoring
“Can our monitoring system grow as we add gases, tools, and production areas?”
Expanding production can create additional gas cabinets, tools, storage locations, and monitoring points.
The centralized architecture supports up to 46 sampling points and more than 15 gases, allowing facilities to consolidate multiple monitoring requirements within one analytical platform
Where Can the MAX300-TGM Monitor Toxic Gases?
One MAX300-TGM replaces hundreds of distributed single-gas sensors by monitoring multiple locations from a centralized analyzer.
Typical monitoring points include:
- Gas cabinets
- Valve manifold boxes
- Process tools
- Exhaust ducts
- Ambient air
- Chemical storage rooms
- Equipment enclosures
- Operator breathing zones
This centralized architecture reduces calibration effort, maintenance labor, spare parts inventory, and overall lifecycle costs.
Toxic Gas Monitoring for Semiconductor Manufacturing
Semiconductor fabs use a wide range of hazardous gases in deposition, etching, cleaning, and other manufacturing processes. Rapid detection of an unexpected gas release is critical for personnel safety, process protection, and production continuity.
The MAX300-TGM provides centralized toxic gas monitoring across critical fab locations including:
Gas Cabinets | VMBs | Process Tools | Cleanrooms | Exhaust Systems | Operator Breathing Zones
Instead of maintaining a large network of individual single-gas detectors, semiconductor facilities can use centralized quadrupole mass spectrometry to monitor multiple gases across multiple sampling locations.
Chemical & Petrochemical Toxic Gas Monitoring
Chemical manufacturing facilities may require hazardous gas monitoring throughout production, storage, loading, mixing, and ventilation areas.
The MAX300-TGM provides continuous multicomponent monitoring for locations including chemical storage areas, production processes, loading stations, mixing operations, and process ventilation systems.
For petrochemical and other industrial facilities, centralized toxic gas monitoring can help protect personnel and equipment while simplifying facility-wide gas detection.
Pharmaceutical & Life Sciences Gas Monitoring

What is a toxic gas monitoring system?
A toxic gas monitoring system continuously detects hazardous gases that could threaten personnel, equipment, or industrial processes. Systems may use distributed gas sensors or centralized analytical technologies such as mass spectrometry.
How does the MAX300-TGM detect toxic gases?
The MAX300-TGM uses quadrupole mass spectrometry to identify and quantify multiple gases from sample points distributed throughout an industrial facility.
How many gases can the MAX300-TGM monitor?
The MAX300-TGM can simultaneously monitor more than 15 gases, depending on the application and system configuration.
How many locations can one MAX300-TGM monitor?
One system can monitor up to 46 sampling points, allowing centralized monitoring across multiple facility locations.
How fast does the MAX300-TGM detect gases?
Process Insights specifies an analysis speed of approximately 0.4 seconds per chemical and gas clearing times of less than 3 seconds. Actual alarm response for a given location will also depend on the sampling configuration and transport time.
That last sentence is important. We don’t want SEO copy to accidentally imply a 0.4-second total leak-to-alarm response at every remote sampling location.
Where is toxic gas monitoring used?
Typical applications include semiconductor fabs, chemical and petrochemical plants, pharmaceutical manufacturing, gas storage areas, process tools, gas cabinets, exhaust systems, chemical storage areas, and other industrial environments where hazardous gas releases may occur.
