Frequestly Asked Questions

What types of gases can Quantus test?

Quantus provides comprehensive testing for a wide range of compressed gases, including but not limited to compressed air, oxygen, nitrogen, carbon dioxide, and specialty gases such as argon. We ensure compliance with standards like ISO 8573 and USP 797.

What standards does Quantus adhere to for compressed gas testing?

Our testing procedures align with industry standards such as ISO 8573, USP 797, and ISO 14644. These standards ensure that our testing meets the highest levels of purity and safety required for FDA-regulated GMP facilities.

What methods does Quantus use for testing compressed gases?

Quantus employs advanced testing methods to ensure the purity and compliance of compressed gases. Our methods include:


Non-Viable Particle Counting: Using laser particle counters to detect non-viable particulates.

Viable Sampling: For aerobic and anaerobic organisms using surface air samplers and media plates.

Dew Point and Water Content Analysis: Utilizing dew point meters to measure moisture levels in gases.

Oil Level Detection:

For oil mist, we use the Drager Impactor method, which detects oil concentrations down to <1 mg/m³.

For oil vapor, we use the SUTO S120 Oil Vapor Sensor, which provides real-time and high-accuracy measurements with a detection limit of <0.1 mg/m³.

The results from both methods are combined to provide a comprehensive total oil content measurement.

Gas Purity Testing: Using gas purity cylinders and specialized test kits to measure the purity levels of various gases.


These methods ensure that our testing meets the stringent standards required for FDA-regulated GMP facilities.

How does Quantus ensure the accuracy of its compressed gas testing?

We utilize state-of-the-art equipment like the SUTO S120 Oil Vapor Testing Instrument, which provides real-time results and high accuracy for vapor detection. Additionally, all our testing equipment is NIST traceable, ensuring precise and reliable measurements.

What should be done if a gas sample exceeds the acceptance criteria?

In the event of a sample exceeding the acceptance criteria, we immediately notify the customer and take corrective actions. This includes purging the connection rig, retesting the point of use, and documenting both initial and retest results to ensure comprehensive reporting and corrective measures.
