Manufactured by:Aquaria Srl based inLacchiarella (MI), ITALY
The diffusive samplers uses very simple tools that can exploit a natural law (that of molecular diffusion) to enrich on a substrate adsorbing substances in the air as gases or vapors. The amount of pollutant sampled may be determined by an appropriate quantitative analysis. Its average concentration is determined by knowing: the duration of sampling, the equivalent range and mass (measured ...

Ammonia diffusion tubes are suitable for long-term monitoring of ambient Ammonia pollution (sampling times are 2-4 weeks). These samplers are simple to use, requiring no specialist skills or power supply, making them an efficient monitoring option. With very low detection limits (in the low parts per billion range), even low levels of Ammonia pollution can be ...
Manufactured by:Ormantine USA Ltd., Inc. based inPalm Bay, FLORIDA (USA)
The largest emissions of Formaldehyde are associated with its manufacture and subsequent use, natural emissions are lower. This tube is used for active (pumped) sampling over a few hours to identify levels of Formaldehyde and other Aldehydes. Concentrations can be measured in the low parts per billion (ppb) range and ...

This tube can simultaneously measure a range of acid gases – Hydrogen fluoride, Hydrogen chloride, Nitric acid, Hydrogen bromide, Phosphoric acid and Sulfuric acid (HF, HCl, HNO3, HBr, HPO4 and ...
Manufactured by:Ormantine USA Ltd., Inc. based inPalm Bay, FLORIDA (USA)
Hydrogen Sulfide (H2S) pollution is associated with an unpleasant odour, as are many other pollutants. Diffusion tubes are an inexpensive way of determining the chemical cause of the odour and are easy to use, requiring no specialist skills. Sampling periods are 2-4 weeks, and therefore the tubes are used to detect the long-term presence of hazardous Hydrogen sulphide gas. Hydrogen sulfide can be ...
Manufactured by:Ormantine USA Ltd., Inc. based inPalm Bay, FLORIDA (USA)
Ambient air monitoring using our Sulfur dioxide diffusion tubes is a simple means of monitoring that requires no further maintenance after installation – an easy, cost-effective method. These Palmes-type tubes are designed for long-term monitoring, and offer measurement of Sulfur dioxide in the low parts per billion to parts per million ...

Dexamethasone phosphate (Dexamethasone 21-phosphate) disodium is a biologically inactive compound which undergoes dephosphorylation by intra-erythrocyte enzymes. The active metabolite, Dexamethasone, is then released into the circulation by simple passive diffusion through cell membranes. Dexamethasone phosphate disodium-encapsulated erythrocyte has the potential ...
