| 500-100 UMEX100 Passive Sampler for Formaldehyde |
| Validation Type |
| Full Passive monitor has passed all NIOSH protocol validation requirements for sampling rate, desorption efficiency, humidity effects, reverse diffusion, storage stability test for reactive compounds whose stability is suspect , and a factorial study that includes interfering compounds. This is the most rigorous test possible and includes all parameters that can affect sampling accuracy (formerly referred to as Level 5). |

This SKC Air Sampling Guide is a reference only to assist users in finding the method, sampling equipment, and sampling media for a specific compound. This publication is intended for general information only and should not be used as a substitute for reviewing applicable government regulations, equipment operating instructions, or legal standards. Users must consult the appropriate sampling method for the compound of interest before sampling. The sampling parameters shown here are suggestions based on the ranges or volume, flow, and time specified in the methods. It is the responsibility of the analyst performing the sampling and analysis steps to adjust the parameters so that the required detection limits can be obtained. The information contained in this document should not be construed as legal advice or opinion nor as a final authority on legal or regulatory procedures.
