Stackline Labs fields stack emissions and stationary source testing campaigns for industrial operators — particulate, multi-metals, oxides of nitrogen, carbon monoxide and total gaseous organics.
Two crews, our own sampling trains, and a habit of telling you what the port access looks like before test day rather than on it.
Protocol review and a pre-test site walk are included. We would rather find a blocked port a fortnight early than bill you for a return trip.
Methods
Reference methods we run routinely. If the permit calls for something not on this list, tell us and we will say plainly whether we can field it or whether you want a bigger firm.
| Method | Measures | Notes |
|---|---|---|
| 1 / 2 | Traverse points, gas velocity | S-type pitot; every campaign starts here |
| 3A | Oxygen and carbon dioxide | Instrumental, for diluent correction |
| 4 | Moisture content | Run with the particulate train |
| 5 | Filterable particulate | Front half; heated probe and filter |
| 7E | Oxides of nitrogen | Instrumental analyzer |
| 10 | Carbon monoxide | Instrumental analyzer |
| 25A | Total gaseous organics | Flame ionization detector |
| 29 | Multi-metals | Including mercury, subcontracted analysis |
| 202 | Condensable particulate | Run in series behind Method 5 |
Work
Permit-driven annual and initial performance tests, plus relative accuracy audits against an operator's continuous monitors. The dates are fixed by the permit, so we plan around your outage calendar rather than ours.
Testing that exists to answer a question — control-device efficiency before and after a rebuild, inlet and outlet loading across a baghouse, or finding out which of two identical lines is the one failing.
Sources
Combustion and process sources at industrial sites. We do not do ambient monitoring, indoor air, or drinking water — those are different laboratories with different equipment.
Enquiries
The fastest way to get a real number from us is the permit language and the stack arrangement. From those two we can usually quote without a call.
