3.1 The storage stability of HCl on silica gel tubes was found to be acceptable. Aqueous HCl was spiked onto 9 silica gel tubes at a level corresponding to 1.0 × PEL. Air with 80% humidity and 25&C was pumped through the tubes at 0.5 Lpm for 15 minutes. Three tubes were analyzed on that day (Day 0).

Get PriceA combustible gas detector measures the presence of explosive or flammable gases according to their LEL (Lower Explosive Limit). It is used for the detection of explosive combustible gas leaks such as natural gas, butane, propane, hydrocarbons, solvents or alcohols.. The response of the combustible gas detector is based on the reference gas from which the explosimeter is set (standard gas).
Get PriceA detector samples the air for specific flammable gases. If the device detects the presence of a gas, it compares the gas concentration to a set level that is programmed into the detector. If the gas concentration surpasses that set level, the detector alerts the user

Get PriceA gas detector is a device that detects the presence of gases in an area, often as part of a safety system. This type of equipment is used to detect a gas leak or other emissions and can interface with a control system so a process can be automatically shut down. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave.
