UMEx 100甲醛被動式采樣器
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 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 | No effect from 5 to 100 cm/sec |
Interferences? | Large amounts of carbonyl compounds may reduce the uptake of formaldehyde. Use in ozone levels < 0.5 ppm. |
Dimensions | 3.4 x 1.1 x .35 in (8.6 x 2.8 x .89 cm) |
Weight | 0.38 oz (10.8 gm) |
| Note: | If sampling in an atmosphere containing formalin, see Sampling Formaldehyde from Formalin Using Passive Samplers for field study information. |
