Isokinetic sampling requires the gas velocity at the sampling probe inlet to match the gas flow velocity inside the stack, and a ratio deviation that is too large makes the collected sample unrepresentative.

UnverifiedImplementing isokinetic sampling involves iterative calculations using the Bernoulli equation and the ideal gas law, and rounding errors in intermediate steps accumulate and affect compliance determinations.72% similarUnverifiedIn EPA stack testing methods, a decimal point error when calculating traverse points or sampling heights will invalidate the entire test.70% similarUnverifiedCompared to methods requiring multiple samples, single forward-pass methods are better suited for latency-sensitive production environments and can serve as output confidence estimation or safety filtering components.64% similarUnverifiedMany sampling methods exhibit quality fluctuations or even degradation as the number of sampling steps increases, whereas CO₂Jump demonstrates a stable performance curve where more steps consistently yield better results.63% similar
