The Thermosorb-N air sampling cartridge is the perfect solution for monitoring nitrosamines levels in the air.
Nitrosamines are known carcinogens and exposure to them should be limited. Monitoring of airborne nitrosamines should be performed to ensure that the environments people are operating are safe. The Thermosorb-n air sampling cartridges are designed specifically for the collection of airborne nitrosamines.
Nitrosamine Sampling made easy.
The Thermosorb-N has been designed with the user in mind. The integral clip easily attaches to most work clothes' pockets or lapels and permits easy removal. The Thermosorb-N is designed to be used with personal sampling pumps. End Caps can be stored on the cartridge itself, so there is no more hunting around for them when sampling is finished, and the cartridge must be sealed.
The Large diameter of the Thermosorb-N Air sampler eliminates the need for a backup section in most applications. In cases where substantial concentrations of N-nitroso compounds are suspected, a second cartridge can be attached to the sampling system “piggyback” style.
The Data Log included with every Thermosorb-N air sampler provides coded labels for the sampler, analysis vials and mailing envelopes to help with sample labelling, as well as providing a convenient form of data entry. The sealable foil pouch provides additional security for transport to and from the field. As the Thermosorb-N air samplers are constructed of opaque plastic, there is no UV degradation of the sample.

Results you can trust
Determination of airborne nitrosamines has been prone to artifact formation (false positives if solid sorbents are used, and sample loss, i.e., false negatives dues to desorption or degradation in solver if wet traps are used). Nitrosamines are also known to degrade in UV light.
The Ellutia Thermosorb-N offers a method for collecting airborne nitrosamines, which overcomes the problems with false positive and false negative results.
Nitrogen oxides can easily react with amines to form nitrosamines. The ease of this reaction suggests that nitrosamines can be artifactually formed either during collection or analysis. Thermosorb-N air samplers contain an artifact trap that includes an amine-trapping agent and a nitrosation inhibitor to avoid this formation. Nitrosamine levels determined from a sample collected using the Thermosorb-N air sampler are representative of airborne nitrosamine levels.
In addition to artifact formation, another problem with other collection techniques involved ultraviolet (UV) light degradation of the collected nitrosamines and desorption of the sample over time or temperature. Thermosorb-N air samplers are made of opaque plastic and employ solid sorbent materials to ensure the sample is not lost.
