What to know before you specify a portable trace chemical identifier.
The MR-AIMS is a handheld ion mobility spectrometer. It identifies toxic industrial gases and other high-toxicity volatile compounds at parts-per-billion levels. It alarms in 15–30 seconds.
It weighs about 1 kg with the battery. It runs at least 10 hours per charge. It is sealed to IP67. Its library holds 60+ substances and can be extended to your own list.
No technology wins on every point. This table helps you pick the right tool. It does not claim one product replaces all others.
| Criterion | MR-AIMS (dual-tube IMS) | Single-tube handheld IMS | Colourimetric tubes | Fixed installed system |
|---|---|---|---|---|
| Sensitivity | Parts per billion | ppb to ppm | Parts per million | Parts per million |
| Identifies substance | Yes | Yes, with switching delay | No; one tube, one gas | Limited, sensor-specific |
| Response time | 15–30 s | Longer; polarity switching | Minutes per sample | Continuous, near real time |
| Coverage | 60+, expandable | Fixed library | One compound per tube | Fixed sensor set |
| Portability | Handheld, ~1 kg | Handheld | Handheld kit | Fixed installation |
| Power | ≥ 10 h battery | Battery | None needed | Mains supply |
| Environmental rating | IP67 | Typically IP54–IP65 | Not applicable | Enclosure-rated |
| Capital cost | Moderate | Moderate | Low | High per point |
| Running cost | Low; periodic service | Low; periodic service | Tubes consumed each use | Calibration contract |
Fixed systems suit known risks at a fixed point. Detector tubes suit cheap single-compound confirmation. A portable identifier earns its place when the substance is unknown, the location varies, or a wrong guess costs a lot.
One instrument replaces several single-purpose detectors. It also cuts time spent on inconclusive investigations. Purchase cost usually dominates. Still, budget for training. Sampling technique affects results more than any specification line.
Industrial toxic gases, odorous gases and other high-toxicity volatile compounds. The standard library holds 60+ substances. It can be extended for your site or mission.
It works at trace level, in the parts-per-billion range. That sits well below concentrations causing immediate harm. Early warning becomes possible.
Within 15 s for Group A: phosgene and organophosphorus compounds. Within 20 s for Group B: sulphur- and arsenic-containing compounds and hydrogen cyanide. Within 30 s for common industrial gases: SO₂, H₂S, NO₂, NH₃, formaldehyde, benzene, chlorine and HCl.
Twelve minutes or less, including the self-test. Most crews power up during transit and arrive ready.
At least ten hours at normal temperature. At least six hours in cold. Carry a spare for long incidents and winter work.
Yes. It is customisable. Add target substances on request. Define the compounds you care about at order time.
Two miniature drift tubes run at once, one per polarity. One tube no longer alternates. You get no switching delay, faster clearing and fewer false alarms from humidity and solvents.
Yes. The IP67 housing is dust-tight and resists temporary immersion. It operates from −20 °C to +45 °C and stores from −40 °C to +55 °C.
No larger than 170 × 110 × 62 mm. No heavier than 1 kg with the battery. It holsters or wears, leaving both hands free.
No. It identifies trace hazards. Confined-space entry still needs a personal multi-gas monitor, ventilation assessment and a permit. It complements those controls.
Operators learn start-up, sampling, interpretation, alarm response and after-use care. Maintainers learn routine service and fault diagnosis. Delivery is on site or remote.
Contact the manufacturer below. State your industry, your substances of concern and your operator numbers. That allows a configured quote and a demo built around your use case.
