Ensuring Purity and Reliability for Critical Manufacturing & Laboratory Processes

ompressed dry air (CDA) is a vital utility utilized across pharmaceutical manufacturing, medical device production, and critical laboratory suites to operate pneumatic valves, clean sensitive parts, and power process equipment. However, contamination in the form of moisture, residual oils, particulate matter, or micro-organisms can compromise product sterility, damage automation equipment, and cause costly batch failures. We deliver comprehensive, ISO-compliant testing and validation services for industrial and medical compressed air systems, verifying that your utility meets strict purity and quality standards at the point of use.

Comprehensive Purity, Contamination & Air Quality Parameters

  • Dew Point & Moisture Analysis

    • Pressure Dew Point Testing

      Measure moisture content and water vapor levels within pressurized lines using calibrated hygrometers to prevent condensation, pipe corrosion, and microbial growth (meeting ISO 8573 Class specifications).

  • Hydrocarbon & Oil Mist Content Testing

    • Total Hydrocarbon Sampling

      Analyze compressed air streams for gaseous and aerosolized oils, lubricants, and total hydrocarbons using advanced PID detectors or gravimetric sampling to ensure zero oil migration into critical processes.

  • Particulate Matter & Solid Contaminant Counting

    • Particle Size Distribution Sizing

      Utilize laser particle counters connected via high-pressure diffusers to count and size solid particulate contaminants across multiple ISO classification thresholds.

  • Microbial & Viable Air Sampling (Optional)

    • Aseptic Bioburden Testing

      Perform viable microbial and fungal air sampling using impaction or filtration methods to confirm that compressed air delivered to sterile core environments is free of living microorganisms.

Frequently Ask Questions

  • How often should compressed dry air (CDA) systems be tested?

    CDA and critical utilities are typically tested upon initial commissioning, after major piping or compressor modifications, and routinely on a semi-annual or annual basis to maintain audit readiness.

  • What standards govern compressed air purity?

    Our testing services comply with ISO 8573-1 (Compressed Air Quality Classes), ISO 12500, USP/EP monographs for medical/pharmaceutical gases, and relevant cGMP guidelines.

  • What happens if a utility sample fails a contaminant test?

    If a test shows elevated moisture, oil, or particulate levels, our team helps isolate the issue—pointing to saturated desiccant dryers, failing coalescing filters, or downstream pipe corrosion—allowing your maintenance crew to rectify the problem before re-testing.

Frequently Ask Questions

  • What standards do you follow for compressed dry air testing?

    Our testing protocols strictly comply with ISO 8573 (Contaminants and Purity Classes), USP monograph requirements, and cGMP utility validation guidelines.

  • How often should compressed dry air systems be tested?

    Critical CDA systems in pharmaceutical and medical manufacturing are typically tested semi-annually or annually, as well as following major compressor or filtration maintenance.

  • What is a pressure dew point and why does it matter?

    Pressure dew point measures the temperature at which water vapor in compressed air begins to condense. Maintaining a low dew point prevents moisture accumulation, which causes pipe corrosion and bacterial growth in utility lines.

  • What documentation is provided upon completion?

    You receive a detailed, audit-ready validation report containing exact measurement values for moisture, oil, and particulates, matched against established ISO 8573 purity classes along with calibration certificates.
