Dräger ORSA 5 - PN 6728891
Dräger ORSA 5 (5 samplers, 5 holders, 5 shipping vials)
PN: 6728891
With the Dräger-ORSA 5, the hazardous substances contained in the air are first collected by adsorption or chemisorption. The sample is then qualitatively and quantitatively tested in the laboratory using instrumental analysis such as gas chromatography (GC), high-performance liquid chromatography (HPLC), UV-VIS photometry or IR spectroscopy. The Dräger-ORSA 5 set consists of: - 5 ORSA collection tubes - 5 ORSA holders - 5 sampling protocols - 5 mailing bags (padded) with label for Dräger analysis service
· ORSA for organic compound lab analysis
| Application Range | |
| Adsorbate | organic compounds which adsorb on activated charcoal by diffusion |
| Sorption agent | coconut shell coal |
| Adsorption capacity | max. 10 mg, depends on substance |
| Adsorption layer |
400 mg |
| Diffusion rate | 1 to 4 µg/ppm x h , depends on substance |
| Sampling rate | 5 to 10 mL/min, depends on substance |
| Response time | approx. 2 s |
| Standard range of measurement | 0.1- to 3-times the limit value for most organic solvents for a sampling period of 8 h |
| Diffusion cross section |
0.88 cm2 |
| Diffusion distance |
0.5 cm |
| Diffusion barrier |
0.5 cm |
| Diffusion resistance coefficient | 0.8 |
| Apparatus constants | 0.71 cm-1 |
| Permissible ambient conditions | |
| Temperature | 5 to 40 |
| Moisture | 5 to 8 % at 20°C |
| Atmospheric pressure | below 1050 hPa |
| Air velocity | at least 1 cm/s |
| Advice for sample-taking |
| Air sampling is carried out in the previously determined measuring period which should be documented. After sample-taking the sampling tube is sent to the laboratory for analysis in the tightly sealed glass bottle. |
