Industrial Scientific recommends clear urethane tubing for sampling exotic gases

Industrial Scientific Corporation recommends the use of urethane tubing when sampling exotic gases to prevent absorption of the gas by the sample tubing.
 
Urethane tubing provides effective resistance against the absorption of exotic gases while still remaining flexible and easy to work with, according to Industrial Scientific. The type of sample tubing is important in gas detection systems, especially when sampling from a confined space.
 
Certain exotic gases may be absorbed by sample tubing, affecting the accuracy of the gas reading. Sulphur Dioxide (SO2), Chlorine (Cl2), and Hydrogen Chloride (HCl) are just a few examples of gases that may be absorbed if appropriate tubing is not used.
 
Through its ongoing research related to portable gas detection monitors, Industrial Scientific Corporation has identified P/N 17065970 clear urethane tubing to have superior resistance to absorption of exotic gases when compared to P/N 17102005 black urethane tubing.
 
This clear urethane tubing has a 1/8 inch inner diameter and 3/16 inch outer diameter, and is ideally suited for use with the pumped versions of the MX6 iBrid and Ventis MX4 gas monitors. Based on its superior performance, Industrial Scientific will now include this clear urethane tubing, P/N 17065970 with the pumped versions of the MX6 iBrid and Ventis MX4.
 
Effective immediately, Industrial Scientific recommends that clear urethane tubing, P/N 17065970 be used with the pumped versions of the MX6 iBrid and Ventis MX4 when sampling for gases including Ammonia (NH3), Chlorine (Cl2), Chlorine Dioxide (ClO2), Hydrogen Chloride (HCl), Hydrogen Cyanide (HCN), Nitric Oxide (NO), Nitrogen Dioxide (NO2), Phosphine (PH3) and Sulphur Dioxide (SO2), or Photo Ionization Detectors (PIDs) used to detect volatile organic compounds (VOCs).
 
In addition, Industrial Scientific continues to recommend the ‘2 & 2 Sampling Rule’ when sampling with a motorised pump and tubing, which states that one should allow for 2 minutes plus 2 seconds per foot of tubing used, prior to noting the monitor readings. This allows time for the gas to reach the instrument and for the sensors to adequately react to any gases present.
