Monitoring of Ambient Formaldehyde Exposure
Ambient Formaldehyde (HCHO) is a carcinogenic volatile organic compound (VOC). It can be released both indoors and outdoors from household products such as glue, wild fire, plants and fuel combustion. Monitoring of atmospheric Formaldehyde is vital in the aspects of health & safety.
Chromatotec Solution
Chromatotec has engineered a compact permeation-based calibration system using paraformaldehyde with advantages over cylinder-based standards, providing a wide and controlled concentration range, predictable output, stable output over one year, fast stabilization, and DNPH-HPLC (ISO 16000-3) certification.
Chromatotec airmoF : Field Formaldehyde Analyzer
The airmoF microfluidic device for formaldehyde is dedicated to on-line monitoring based on the Hantzsch reaction. Designed for ultra-trace detection and field robustness, it delivers:
- High sensitivity with detection < 0.1 ppb
- Auto-zero at every cycle to eliminate drift
- No influence of humidity (tested up to 50% RH)
- Excellent linearity (R² > 0.99)
- Internal HCHO module calibration

Chromatotec microF : Portable Formaldehyde Analyzer
Chromatotec microF is a compact Formaldehyde analyzer which allows continuous and real-time qualification and quantification of Formaldehyde. Time resolution is down to few seconds and detection limit is lower than 10 ppb.
Picarro Solution
Picarro is the leading provider of enhanced Cavity Ring-Down Spectroscopy (CRDS) analytical solutions, with more than 25 years in business, dedicated to measuring high-precision greenhouse gases, stable isotopes and other gases to advance environmental research, ensure regulatory compliance, and create safer workplaces and communities.
Picarro offers monitoring of Methane CH4 (Methane), CO2 (Carbon Dioxide), N2O (Nitrous Oxide), CO (Carbon monoxide) [Including δ13C & δ18O], NH3 (Ammonia) as well as HCHO (Formaldehyde), etc.
G2307 Gas Concentration Analyzer
The Picarro G2307 Gas Concentration Analyzer provides precise, real-time measurement of HCHO, methane (CH4), and water (H2O) vapor simultaneously. It incorporates coated components in the critical gas pathway. This reduces the propensity of HCHO molecules to adhere to pathway surfaces, which improves measurement response time. The analyzer is an ideal solution for atmospheric research and monitoring of formaldehyde from automobile and aircraft exhaust, photochemical smog, and incinerator emissions, and it can be used to measure sensitive trace and ambient formaldehyde for indoor air quality.
Key Feature
- Fast, continuous, real-time measurement of HCHO
- Long-term stability for infrequent calibration
- Small footprint, field or laboratory deployable with no consumables required
- Automatic water correction and dry gas mole fractions reporting
Key Specification
- Precision at 2 sec, 10 sec, 5 min : 1.2, 0.6, 0.1 ppb (HCHO); 20, 10 and 2 ppb (CH4)
- HCHO rise time (10 – 90%) and fall time (90 – 10%) is less than 1 min (0 – 20 ppb)
- Drift at standard temperature and pressure (STP) over 24 hours is 1.5 ppb
