Is capture the same as collection efficiency?

No. Capture reaches the control device; collection removes contaminant from the stream inside that device.

Can I use dust-bin weight as captured mass?

Not directly. It excludes material that entered the collector but escaped or remained in its inventory.

A larger value indicates inconsistent boundaries, stored-material release or measurement error.

No. Exposure requires an appropriate occupational sampling assessment.

Check how much generated contaminant reaches the control system. Enter a matched process mass balance and the source-capture target for that test.

Contaminant Captured at Source: Mass entering the control system from the defined process.
Contaminant Generated by Process: Matched total generated mass before hood capture.
Required Source Capture: Capture target specified for this process and test.

Why require captured mass below generated mass? A larger value indicates inconsistent boundaries, stored-material release or measurement error.
Does high capture establish worker exposure? No. Exposure requires an appropriate occupational sampling assessment.
