VOC Calibration Gas — 50 ppm

VOC stands for Volatile Organic Compound — a category of carbon-containing chemicals that evaporate readily at room temperature. In gas detection, VOCs are monitored because many are hazardous to human health or the environment. Gas detectors and analyzers calibrated with certified VOC calibration gas mixtures can accurately identify and quantify compounds like formaldehyde, acetone, and dimethyl sulfide in ambient air or process streams.

NIST-traceable means the calibration gas concentration has been verified against standards maintained by the National Institute of Standards and Technology. This chain of traceability ensures the gas mixture meets documented accuracy requirements. For regulatory and industrial applications, NIST-traceable calibration gases are essential for defensible measurement data and compliance with standards such as EPA Method 320.

SpecGas Inc. produces VOC calibration gas mixtures at PPB (sub-ppm) and low PPM levels, typically ranging from 1 ppm to 100 ppm. The 50 ppm concentration is commonly used for mid-range detector calibration. Custom concentrations outside these ranges can be blended to exact customer specifications using gravimetric blending techniques.

VOC calibration gases are available in disposable aluminum cylinders, disposable steel cylinders, refillable aluminum and steel cylinders, and nickel-plated cylinders. Cylinder capacities range from 17 liters to 2,000 liters. Disposable cylinders are ideal for field applications and overseas shipping, while refillable options suit laboratory and long-term industrial use.

Yes. SpecGas Inc. specializes in custom gas blends produced to exact client specifications. Whether you require a single-component VOC at a precise concentration, a multi-component mixture including formaldehyde or moisture, or an unusual compound that larger suppliers cannot provide, SpecGas's in-house blending experts can accommodate complex requirements with adaptable tolerances.

VOC calibration gas at 50 ppm is used in calibrating gas chromatographs, FTIR spectrometers, photoionization detectors, and ambient air quality monitors. Applications include stack emission testing per EPA Method 320, industrial hygiene monitoring, environmental compliance programs, semiconductor and electronics manufacturing process controls, and laboratory research requiring traceable analytical standards.
