Topic “Arsine”
Arsine is the chemical compound with the formula AsH3. This flammable, pyrophoric, and highly toxic gas is one of the simplest compounds of arsenic. Aside from its lethality, it finds applications in the semiconductor industry and for the synthesis of organoarsenic compounds. At its standard state, arsine is a colorless, denser-than-air gas that is soluble in water (200 mL/L) and in many organic solvents as well. Whereas arsine itself is odorless, owing to its oxidation by air it is possible to smell a slight, garlic-like scent when the compound is present at about 0.5 ppm. This compound is generally regarded as stable, since at room temperature it decomposes only slowly. At temperatures of ca. 230 °C decomposition to arsenic and hydrogen is rapid. Several factors, such as humidity, presence of light and certain catalysts (namely aluminium) facilitate the rate of decomposition.
Beacon 110 Single Channel Wall -Mount Controller
The Beacon 110 is a powerful, low cost fixed system controller for one point of gas detection. It is microprocessor controlled, versatile, simple to install and operate, and priced to be the industry's best value single gas detection controller. It is capable of accepting RKI sensors directly for LEL level combustibles, Oxygen, Hydrogen Sulfide, or Carbon Monoxide. The Beacon 110 can also accept any 4-20 mA transmitter (2 or 3 wire, 24 VDC). Sensors can be mounted directly at the Beacon 110 housing, or can be wired remote from the controller.
Gas detection should not be complicated. The Beacon 110 is gas detection simplified.
The Beacon 110 is a fixed mount, single channel continuous-monitoring gas monitoring controller. All user adjustable parameters may be accessed using push button switches.
EAGLE 2 Three Gas Monitor
RKI is proud to produce the most versatile portable gas detector on the market. The EAGLE is a powerful instrument that does more than offer standard confined space protection. The EAGLE also provides detection combinations never before offered in a portable gas monitor featuring the industry's widest selection of high quality, long life and field proven sensors.
EAGLE Multigas Monitors are available in standard and custom configurations
The EAGLE's ergonomic design offers easy access to controls such as autocalibration, alarm silence, demand zero, peak hold and a wide variety of other features.
FP-260 Toxic Gas Monitor
FP-260The FP-260 is a highly sensitive toxic gas monitor using a gas detection cassette tape which is almost free of interference from other gases. Since the detection tape responds only to the chemical reaction of the gas being measured, there is no interference from hydrogen or organic gases.
High Sensitivity Toxic Gas Monitor for Phosphine, Silane, Diborane, Arsine, Disilane, Hydrogen Sulfide, Phosgene, Chlorine, and Hydrogen Selenide
Features
• Ideal for low gas concentration (ppb detection)
• Easily replaceable plug-in tape cassette
• Cassette tape remainder display included
M2 Series Explosion Proof Gas Transmitters
The RKI M2™ is a state-of-the-art transmitter that can operate as an independent, stand-alone system or as part of a system connected with an analog or digital signal to virtually any controller, PLC, or DCS. Setup procedures are simplified with user friendly push buttons and LCD menus. It utilizes a magnetic wand technique for performing non-intrusive calibration. The M2 provides an automatic zero drift correction feature, which results in more stable readings and reduces the need for adjustments due to sensor aging.
The M2 represents the latest leading edge technology in sensor / transmitters today.
