Performance Profile

Sampling Rate for Formaldehyde

28.6 ml/min with a RSD of 7.6% at wind velocity of 5 to 100 cm/sec for 15 minutes to 24 hours
20.4 ml/min at wind velocities < 5 cm/sec for 1 to 7 days

See the More Information tab for UMEx 100 sampling rates for other aldehydes.

Detection Principle

Formation of stable DNPH-hydrazone in the presence of formaldehyde

Validation Range

0.06 to 3.0 ppm

Lower Detection Limits

15 min: 200 ppb (0.24 mg/m3)
8 hrs: 5 ppb (0.006 mg/m3)
24 hrs: 2 ppb (0.002 mg/m3)
7 days: 0.2 ppb (0.0002 mg/m3)

Shelf-life

12-mos from date of manufacture at < 39.2 F ([4 C])

Capacity

29 μg/sample

Analysis

Solvent extraction and analysis by HPLC (high-performance liquid chromatography) with UV detection

Accuracy

± 25%, exceeds OSHA requirements

Storage

Before use: < 39.2 F ([4 C])
After use: < 39.2 F ([4 C]) and analyze within 3 weeks
Do not store with food.

Temperature Effects

No effect on sampling rate between 10 and 30 C

Humidity Effects

No effect from 10 to 80% relative humidity (RH)
Do not use sampler below 10% RH.

Wind Effects
