Description
Honeywell MIDAS Sensor Cartridge for Silane (SiH4) 0.18-2 ppm (Low Level)
Several Honeywell MIDAS® cartridges can be configured to read a number of different gases based on a common chemical family. Actual details for the sensor detection range are included in the sensor cartridge specification sheet and the MIDAS® technical manual. MIDAS® sensor cartridges can be ordered as part of a Kit with the universal MIDAS® transmitter, or as a replacement part. The detectable range is listed. With the exception of O2 (where ambient concentration is typically 20.9%), the sensors will display zero when no gas is present. All Cartridges with the format MIDAS-E-XXX are supplied with a 2 year (24 month) warranty.

Each Midas sensor is potentially cross sensitive to other gases and this may cause a gas reading when exposed to other gases than those originally designated. The table below presents typical readings that will be observed when a new sensor cartridge is exposed to the cross sensitive gas (or a mixture of gases containing the cross sensitive species).
| Gas / Vapor | Chemical Formula | Concentration Applied (ppm) | Reading (ppm SiH4) |
|---|---|---|---|
| Ammonia | NH3 | 100 | 0 |
| Arsine | AsH3 | 1 | 1 |
| Carbon Monoxide | CO | 2000 | 0.1 |
| Chlorine | Cl2 | 5 | -0.6 |
| Diborane | B2H6 | 1 | 0.7 |
| Ethanol | C2H5OH | 500 | 0 |
| Hydrogen | H2 | 5000 | Max 0.2, Avg 0.1 |
| Hydrogen Chloride | HCl | 8.7 | 1.6 |
| Hydrogen Fluoride | HF | 10 | 0 |
| Hydrogen Sulfide | H2S | 5 | 1.8 |
| Iso Propanol | C3H7OH | 500 | 0 |
| Nitrogen Dioxide | NO2 | 50 | -11 |
| Phosphine | PH3 | 1 | 1.4 |
