Characteristic factors of atmosphere online monitoring is paid more and more attentions. Heavy metals online monitoring is one of those factors spread in some industrial park like metallurgy industry. But now, it is in lack of technological acceptances and operation requirements about heavy metals online monitoring. Based on analyzing of one online heavy metals monitoring system in Baosteel, we discussed the necessary technological acceptances to satisfy the monitoring needs. The main performance acceptances we considered are repeatability≤5 %, linearity0.99, accuracy≤15 % and stability≤10 %. Detection limit testing, blank membrane check, sampling accuracy and stability testing are necessary too. At last, based on the experience of routine operation of this system, we bring up some operation requirements about quality controlling and system maintains, and can help to meet the standardized demand of monitoring quality.
